Abstract

The utility model discloses a trace upper sample pipetting gun head, including a conventional pipette suction head and a syringe needle tip, wherein the syringe needle tip is inserted in the pipettor suction head, heated and hermetically combined. The utility model greatly reduces the experiment cost under the precondition of ensuring the upper sample quality, and has higher application value.

Description

Sample liquid-transfering gun head on a kind of trace
Technical field
The utility model belongs to the molecular biology experiment research field, more specifically, relates to sample liquid-transfering gun head on a kind of trace.
Background technology
Vertical slab electrophoresis commonly used in molecular biology experiment is a kind of laboratory facilities in order to small-molecule substances such as isolating nucleic acid, protein.For better separating these small-molecule substances, its colloid approaches (in the 1mm that is everlasting) usually; Be to guarantee that enough electrophoresis applied sample amounts then need to strengthen the degree of depth (often being about 15~20mm) in sample hole, just caused certain degree of difficulty like this on electrophoresis during sample, technical micro syringe commonly used or special-purpose liquid-transfering gun head are deep into and release sample solution slowly bottom the sample hole at present.
These existing products are because specification requirement and required precision height therefore depend on import, thereby expense are high more.And in the use, because operation is required, these are again as consumptive material, thereby make the experimental study cost high.The price of the present micro syringe of using always is about 30~100 yuan, and the liquid-transfering gun head price of specialty is more expensive, and the quotation of every box is more than 500 yuan.
The utility model content
The technical problems to be solved in the utility model provides a kind of sample liquid-transfering gun head on the trace that the normal experiment consumptive material made, can reduce greatly experimental cost that utilizes.
For solving the problems of the technologies described above, the utility model provides sample liquid-transfering gun head on a kind of trace, comprises conventional liquid-transfering sucker and needle point, and described needle point is to be inserted in the pipettor suction nozzle, through heating airtight be combined into by the syringe needle tip portion.
The utility model has adopted the most frequently used basic consumptive material in laboratory, method by simple heating connects both driving fits, utilize conventional liquid-transfering sucker the imbibition space and can with the supporting use of each standard pipettor, utilized thin and long syringe needle to reach desirable application of sample effect simultaneously, syringe needle can be delivered to the well bottom easily and go up sample smoothly during operation.
The utility model is cheap, and the product of finishing only needs extremely low cost, but result of use never is worse than prior art.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is described in further detail.
Fig. 1 a, Fig. 1 b are respectively the utility model manufacturing process schematic diagrames.
Fig. 2 is the utility model structural representation.
The specific embodiment
Embodiment
As shown in Figure 2, the utility model comprises conventional liquid-transfering sucker 2 and the needle point 1 that is made of the syringe needle tip, and it is with in the most advanced and sophisticated insertion of the syringe needle pipettor suction nozzle 2, through heating airtight be combined into.
For guaranteeing enough applied sample amounts, liquid-transfering sucker 2 is the liquid-transfering sucker of the conventional consumptive material 200ul in laboratory in the present embodiment; For being fit to the last sample bore dia of most of vertical slab electrophoresis, present embodiment is selected the syringe needle of 0.5mm diameter specifications for use, intercepting leading portion tip portion, and length is advisable with 50mm.
Needle point 1 inserts liquid-transfering sucker 2 tips, and with 2 airtight connections of liquid-transfering sucker, concrete operations such as Fig. 1 a are shown in Fig. 1 b.Clamping needle point 1 is also inserted about 1~2mm in the liquid-transfering sucker 2 with afterbody, and is hot to needle body with electric iron or alcolhol burner heating syringe needle, clutches the connecting portion of pressurization needle point 1 and liquid-transfering sucker 2 rapidly, treats its cooling both natural driving fits of back.
The liquid-transfering sucker of finishing is enclosed within on the standard pipettor, and draws reagent, intact suction nozzle should be able to unresisted absorption reagent.And the binding site of liquid-transfering sucker 2 with needle point 1 afterbody can be placed under the liquid level, make piping and druming action checking joint area and have or not bubble to overflow, do not show then that as having sealing is good, can be used for experimental implementation.

Claims (5)
