Thermoreactors
WHAT IS COD?
The pollution caused by the organic and inorganic substances in a waterway (wastewater or surface water) can be evaluated using a parameter called COD. COD stands for Chemical Oxygen Demand for the oxidation of substances dissolved and suspended in the water. By determining the COD it is possible to proportion chemically oxidable substances with energy oxidants such as potassium bichromate in a strongly acidic solution. The acid environment is caused by the presence of concentrated sulphuric acid. Both inorganic compounds and organic substances can be oxidized. This determination also makes it possible to proportion organic substances using the equivalent biological method (BOD: Biological Oxygen Demand), for example, cellulose. Since oxidation takes place in drastic conditions, it is more complete than biological oxidation and as a consequence the COD value of a given sample is, in most cases, higher than the corresponding BOD value. Thermoreaction (digestion) of a sample The digestion of the sample is one of the most important steps in many chemical reactions. Digestion is carried out in order to convert low-solubility compounds or substances present in the form of aggregates into soluble compounds, to degrade organic substances into inorganic molecules, or to eliminate interfering substances and solubilize metallic ions. Digestion takes place by adding decomposition reagents to the sample which is then kept at a set temperature for a certain length of time. ECO series thermoreactors Velp Scientifica programmable thermoreactors are a cutting edge solution able to meet the most diversified temperature control requirements. Velp ECO thermoreactors have been studied for COD analysis in particular as well as for the wetdigestion preparation of samples for the determination of metallic and non-metallic elements in organic and inorganic materials such as minerals, alloys, animal feeds, soils, sediments and organic tissues. The solutions Velp offers ensure a high degree of accuracy and reproducible results. Velp Scientifica thermoreactors combine perfectly with Macherey-Nagel Nanocolor kits for analyzing parameters such as COD, nitrogen and total phosphorus, metals, hydrocarbons, AOX and TOC. Velp Scientifica is, in fact, Macherey-Nagels official partner for the Italian market. Used in combination with the Macherey-Nagel Nanocolor kits for analyzing COD (COD 40, 60, 160 and 1500), Velp Scientifica thermoreactors have been given the stamp of approval as suitable for the ST-COD method Determination of the chemical oxygen demand for water quality in compliance with ISO 15705. COD in 30 minutes! Thanks to the newly introduced temperature of 160C, the ECO series of thermoreactors are able to carry out COD analyses in just only 30 minutes.

BOD Analysis
WHAT IS BOD?
BOD (Biochemical Oxygen Demand) measures the amount of oxygen consumed by microorganisms in decomposing organic matter in wastewater or stream water. The microorganisms contained in or inoculated into a sample of water containing a biodegradable organic substance consume oxygen owing to their metabolic activity and generate a corresponding volume of carbon dioxide. By working in a closed system and forcing the carbon dioxide produced to be absorbed by a highly alkaline substance, a progressive reduction of the gas pressure is obtained. This pressure reduction can be measured using appropriate manometers. The conventional incubation period at 20C is currently considered to be 5 days and the BOD value obtained is called BOD5. This value corresponds (with good reproducibility considering all the aspects of the technique) to 70% of what is known as BODlast (the value obtained after total oxidation requiring 21-28 days). Instruments for BOD analysis In conformity with international regulations concerning the safety of workers and the safeguard of the environment, VELP Scientifica has developed an innovative ecological system (mercury-free) for determining the BOD with microprocessor using manometric technology. Various solutions are available according to need. Accessories for control tests Water quality analysis calls for systematic research work and the accuracy and precision of the instruments used must be monitored constantly. Velp offers two new accessories to support the analyst in carrying out control tests on Velp instruments: - BOD Sensor Check, a device that carries out a quick test to check that the BOD Sensor is working properly. Code No. A00000135. - Control Test Tablets to check the correct functioning of the system and the calibration of the BOD Sensor's pressure sensor through a 5-day test. Code No. A00000136.

BOD Analysis
The BOD Sensor has an ergonomic structure designed and optimized to ensure ease of handling and reading. It is manufactured using the most modern and advanced construction techniques and is fitted directly to the bottle containing the sample. A microprocessor-controlled pressure transducer transfers the BOD value to the display. The BOD Sensor automatically stores 5 BOD measurements at 24-hour intervals so that analysis can also be performed over weekends. It is also possible to obtain a direct reading of the BOD value on the display at any time, even after five days. The BOD Sensor does not require any electrical connection.

JAR TEST AND LEACHING TEST
JAR TEST The type of chemical coagulant to be adopted for removing suspended solids from wastewater and the dosage required are established based on laboratory results obtained from the so-called Jar Test. Multiple stirrers with reproducible stirring speeds mean standard test conditions can be adopted, a basic requirement in order to obtain reliable results. Due to constant variations in the contents of water the test should be repeated with a frequency dictated by specific needs. LEACHING TEST This is a test run on solid wastes to be sent to the dump that uses diluted acetic acid or carbon dioxide-saturated water in order to detect the presence of toxic heavy metals.

The multiple stirrers with reproducible stirring speeds allow standard conditions for the tests to be adopted, a basic requirement in order to obtain reliable results. The sample being examined can be backlit using a special switch found on the front panel making for easier readings. The instruments have an ergonomic design and the control panel is tilted for easier parameter settings and readings. The rotation speed can be programmed from 10 to 300 rpm with 1 rpm intervals and the time remaining can be set to hours or minutes.
The JLT 4 and JLT 6 are supplied with switching power supply and European plug.

Homogenizer
The OV5 homogenizer is composed by a smooth motor that permits to work in a very safe and comfortable way. Top speed of high 30000 rpm rate, reduces processing time significantly. Smooth start prevents unnecessary spills and an additional feature of automatic overload protection increases the life span of the motor. SHAFT The OV5 homogenizer has only one shaft model suitable for all the applications and configurable with different models of rotors / stators. The shaft, thanks to the construction material stainless steel 316L and the PTFE sheats, grants a high resistance and durability. ROTOR / STATOR PRINCIPLE The rotor /stator system consists of a rotor which rotates at high speed within a stationary stator. The rotor and the stator have one or more rows of sharp-edged teeth. Because of the high rotor speed, the medium to be processed is automatically sucked axially into the dispersing head and is then pressed radially through the slots of the rotor-stator arrangement. The wide range of rotors / stators assures the most suitable solution for the different applications.

Digesters
Digesters with programmable temperature ramps
The mineralization units of the DK series are designed for digesting solid and liquid samples in order to determine the nitrogen/protein content according to the Kjeldhal method. The digesters are made up of a heating block in aluminum that offers excellent thermal homogeneity, with a maximum working temperature of 450C. The blocks temperature is controlled by dedicated microprocessor electronics. The temperature probe does not require calibration since the electronics sees to its self-calibration every time the device is turned on. All of this makes it possible to obtain excellent test precision and repeatability. You can select up to 20 work programs with 4 temperature ramps for each program. In compliance with the GLP (Good Laboratory Practices), the data referring to the tests being run can be sent to a printer or PC for storage. All Velp Scientifica digesters have a special tube and fume hood support system able to help cool the samples, make their treatment safer and save space. In order to neutralize the fumes produced during the digestion, the DK digesters should be combined with a proper aspiration pump and fumes neutralization system. Velp suggests the use of the DK digester in combination with the JP pump and the SMS scrubber unit. Velp Scientifica offers a complete range of digesters able to house tubes of different sizes for Kjeldhal analyses ( 42mm volume max 300 ml) and for microKjeldhal analyses ( 26mm volume max 100 ml).

Distillation Units
Innovative Velp Scientifica titanium condenser Velp Scientifica has developed and patented the innovative condenser made of composite material which is able to ensure high performance and considerable water savings. The below graph shows the high efficiency of the new condenser compared to the traditional glass condenser found on the market. It is important to note that while maintaining a constant water flow rate of 1 l/min at a high water temperature, the condenser made of composite material is able to take the temperature of the distillate to a value that is always below the threshold value (35C), as indicated by the Kjeldahl method. You can see in the graph that the condenser made of composite material allows us to attain a 31C distillate temperature at a supply water temperature of 31C; in comparison, the traditional glass condenser is able to produce a distillate with a temperature of 41C (with the chance of losing nitrogen), supply water temperatures being equal. The condensers high efficiency lets the operator perform analysis with minimum water consumption. The remarkable heat exchange in fact lets us use a supply water flow rate of even 0.5 l/min for performing analysis correctly. VELP Scientifica offers a complete range of Distillation Units that can be programmed with different levels of automation and that are designed to meet the most diversified laboratory needs: - Basic model - Semi-automatic model - Automatic model (with possibility of connection to an external titrator) - Automatic model with integrated Titrator UDK 127 UDK 132 UDK 142

Solvent extractors
SOLVENT EXTRACTION
Solvent extraction is used for determining different components of products derived from agriculture, industry or contained in environmental samples. Soxhlet extraction is one of the most widely used analytical techniques. It has been slightly altered in different aspects, in some cases in the attempt to increase the temperature of the solvent coming into contact with the mixture to be extracted, in order to cut the extraction time. The modifications introduced by American chemist Edward L. Randall are some of the most effective for this purpose. Velp Scientifica solvent extractors operate in accordance with the Randall technique. New thimbles for solvent extraction Velp offers new thimbles for the SER 148 solvent extractor that are able to provide accurate and reproducible analytical results. Thanks to the use of the new accessories, the extraction cycles performance is further improved owing to the extreme thinness (1 mm) that allows the solvents flow through the thimbles wall to be faster. The abovementioned thickness features and optimum pressing of the cellulose fibers make the surface of the new thimbles smooth and compact. The new accessories (33 x 80 mm) are made of high quality cotton cellulose fiber.

Soxhlet technique The solubilization of extractable components is performed by a cold solvent dropping from a reflux condenser. Consequently a complete extraction lasts many hours. Randall technique The first phase of extraction is performed by immersing a sample containing thimble in boiling solvent followed by a washing with cold refluxing solvent. The fast solubilization achived by the hot solvent results in a sharp reduction of extraction time. IP55 protection rating The acronym IP International Protection denotes a standard international protection rating, and the number that follows (e.g. 55) indicates the electronic protection level of the instrument in accordance with the European CEI EN 60529 standard. In particular, the first number (5 in the specific case of the SER) is, on a scale of 0 to 6, the level of protection against the accidental access of solid objects to the dangerous parts of the instrument. The second number (5 in this case) indicates the level of protection against water penetration on a scale of 0 to 8.

RAW FIBER
Vegetables and commercial products deriving from them are made up of substances belonging to different categories: - carbohydrates, proteins, fats, mineral salts; - one non-digestible part consisting of polymers (lignin, cellulose, hemicellulose, pectin) called fiber. There are many reasons why it is very important to determine the fiber content, and a few of the most important are: NUTRITIONAL REASON Human beings and animals need an intake of a certain quantity of fiber so that the digestive system works well. Its quantity must be carefully controlled since a high intake could cause problems of indigestibility, whereas a low intake could cause irregularities in the functioning of the digestive tract. ECONOMIC REASON Companies that manufacture foods and animal feeds use as much fiber as a raw material as they are allowed since it is a low-cost food product component. LEGISLATIVE REASON The authorities of almost all countries require manufacturers of packaged foods and animal feeds to declare the fiber content on the packaging as part of the nutritional table. CRUCIBLES Crucibles are to be considered consumable, and their lifetime is closely tied to their use and proper cleaning. The average lifetime is 20-30 analyses. Crucibles have class 2 porosity according to Jenas definition, with 45 m (40 60 m) (ASTM) holes, class C in the USA. In particular, the lifetime of crucibles is closely correlated with their proper use in the muffle furnace for analyzing ashes and their proper cleaning in keeping with what is recommended in the operating manual. Tips for crucible treatment in a muffle furnace The heating and cooling of glass crucibles for determining ash content require special care in order to keep them from breaking. Both the heating and cooling of glass conducted at speeds that are too high induce tensions between the various parts that lead to breakage, particularly close to grazes or in particularly stressed areas such as, for example, the junction between the crucible body and the filter disk. Bear in mind that the temperature of 550 corresponds to the beginning of the plastic state of the glass, and therefore it should not be be exceeded.

Temperature (TC)
Recommendations for getting a constant weight Crucibles removed from a stove or muffle furnace are to be cooled in a desiccator. The guarantee that a sample has been completely dried is given by the obtainment of two identical weights performing two weighings at about half an hour from each other (constant weight).

The samples that have to be subjected to calculation of the raw fiber must have less than 1% fat content. If the fat content is greater than 1%, you have to carry out preliminary extraction using acetone, hexane or petroleum ether. The coex instrument was developed in order make degreasing of the samples inside the crucibles that will then be used on the FIWE 3 or FIWE 6 for the consequent determination of raw fiber.

Dimension (WxHxD): 410x500x295 mm (16.1x19.7x11.6 in) What is the difference between dietary fiber and raw fiber? It is basically an analytical type of difference. Both the procedure for determining the dietary fiber and that for determining the raw fiber are aimed at calculating the indigestible residue of a food, or that is to say, everything that is not fats, proteins or carbohydrates. Whereas the procedure for determining dietary fiber envisages using enzymes, that for determining raw fiber uses only chemical reagents (acids and bases). The procedure for determining dietary fiber exposes the sample to a series of enzymatic digestions that simulate the real digestive process which takes place in the human and animal digestive tract,

calculating the undigested residue remaining at the end of the analysis. The official analytical reference procedure is: AOAC 985.29. On the other hand, in analyzing raw fiber the sample is digested using diluted solutions of acids and bases, and here as well the final undigested residue of the starting food is measured. In this case the most widely used official procedure is the Weende method (official in Italy, France, England, Sweden and the USA). Generally, dietary fiber analysis is carried out on foods intended for human nourishment, whereas raw fiber analysis is carried out on animal feeds or on raw materials of vegetable origin, e.g. cereals.

SHELF - LIFE
The reactions occurring between oxygen and several sensitive components of foods is one of the most important causes of quality alteration of food products. In particular, autoxidation (or growing rancid) of fats contained in foods is recognized as being one of the main factors conditioning the shelf life (commercial life) of the foods. For this purpose Velp Scientifica has developed OXITEST, an innovative research instrument able to provide very valuable additional information about the fat oxidation processes in sample of foods, oils and fats. OXITEST lets you learn the oxidative stability of the fats contained in a food (solid, pasty or liquid) within a very short time and therefore be able to forecast the foods shelf life. Market: food and feed industry, fat and oil industries, research centres. Fields of applications: prediction of oxidation stability during shelf life studies, rapid comparison among different product formulas or verification of different lots of the same raw material. Other analytical techniques can be associated with use of Oxitest. One of the most widely used is analysis by gas chromatography for estimating the formation of compounds due to the products oxidation.
The induction period and the oxidation curve of the sample can be displayed graphically.

SFC 5 Solid Fat Content Solution for fat thermal behaviour studies
Use of the analytical Nuclear Magnetic Resonance technique for studying the thermal behaviour of fats contemplates that they be carefully prepared before the analysis is performed. It is, in fact, necessary to thermostat the samples at different temperatures in order to prepare them for the final measurement. Velp Scientifica developed SFC 5 for this purpose. It is an innovative instrument able to thermostat samples in the temperature range of 0 to 60C, as required in the official sample preparation method. SFC 5 is a compact unit that is one of a kind on the market. It cools (with 0.1C precision) samples for the subsequent determination by Nuclear Magnetic Resonance. The instrument is made up of 5 different blocks, each with 9 positions for housing 10 mm NMR tubes. Each block has independent thermoregulation, with the set temperature shown on the display. Unlike normal thermostatted water baths, this feature lets SFC 5 thermostat samples at the different temperatures required by the official method simultaneously. Application fields: fats manufacturers, food industry, public and private research institutions. Main application: thermostatting fat samples in a temperature range of 0 to 60C as preparation for Nuclear Magnetic Resonance analysis.
Benefits Heating and cooling of the sample in a compact instrument High reliability and precision of temperature The instrument works according to the official method UNI EN ISO 8292
