    Ali Asghar Chunawala
    The document describes several common laboratory instruments used in biotechnology and their functions, including an autoclave for sterilization, a water bath for temperature-controlled incubation, a hot plate for precise heating, and an incubator for cultivating microorganisms under controlled conditions. Other instruments discussed are a centrifuge for separating molecules by density, a micropipette for precisely measuring small liquid volumes, and tools like graduated cylinders, microscopes, balances, petri dishes, beakers, and Eppendorf tubes used for various preparation, measurement, observation, and storage purposes. A laminar flow cabinet is also covered, which protects samples from contamination during work.

    Identifying Lab

    Instruments in
    Biotechnology
    Characteristics & Functions of Lab Tools
    Autoclave
    • Autoclaves operate at high
    temperature and pressure in order
    to kill microorganisms and spores.
    • They are used to decontaminate
    certain biological waste and sterilize
    media, instruments and lab ware.
    Waterbath
    • A water bath is a laboratory
    equipment that is used to incubate
    samples at a constant temperature
    over a long period of time.
    • Water bath is a preferred heat source
    for heating flammable chemicals
    instead of an open flame to prevent
    ignition.
    Hot Plate
    • A lab hot plate is an elementary
    piece of laboratory equipment that
    is mainly used in chemistry and
    biology for heating at precise
    temperatures.
    • Hot plates are laboratory tools
    used to uniformly heat samples
    Incubator
    • Incubator, in microbiology, is an
    insulated and enclosed device that
    provides an optimal condition of
    temperature, humidity, and other
    environmental conditions required
    for the growth of organisms.

    • An incubator is a piece of vital


    laboratory equipment necessary for
    the cultivation of microorganisms
    under artificial conditions.
    Centrifuge
    • Centrifugation is a method of
    separating molecules having
    different densities by spinning
    them in solution around an axis
    (in a centrifuge rotor) at high
    speed.
    • It is one of the most useful and
    frequently employed techniques
    in the molecular biology
    laboratory.
    Micropipette

    A micropipette is a common yet an


    essential laboratory instrument used to
    accurately and precisely transfer volumes of
    liquid in the microliter range.

    A micropipette can come in one of many


    standard sizes, and the most common can
    measure out a volume between 0.1
    microliters and 1000 microliters. This is
    0.0001 milliliters to 1 milliliter
    Graduated Cylinder
    • A graduated cylinder, also known
    as a measuring cylinder or mixing
    cylinder is a common piece of
    laboratory equipment used to
    measure the volume of a liquid
    • Each marked line on the
    graduated cylinder represents
    the amount of liquid that has
    been measured.
    Compound Microscope
    • A compound light microscope is a
    microscope with more than one
    lens and its own light source.
    • In this type of microscope, there are
    ocular lenses in the binocular
    eyepieces and objective lenses in a
    rotating nosepiece closer to the
    specimen.
    Electronic Balance
    • Electronic balance is an instrument
    used in the accurate measurement
    of weight of materials.
    • Electronic balance is a significant
    instrument for the laboratories for
    precise measurement of chemicals
    which are used in various
    experiments..
    Petri Dish
    • Petri dish is majorly used as
    laboratory equipment in the field
    of biology & chemistry.
    • The dish is used to culture cells
    by providing storage space and
    preventing them from getting
    contaminated.
    Beaker
    • Beakers are useful as a
    reaction container or to hold
    liquid or solid samples.
    • They are also used to catch
    liquids from titrations and
    filtrates from filtering
    operations.
    Eppendorf
    • Eppendorf Tubes are single-use
    tubes made from polypropylene
    for preparing, mixing,
    centrifuging, transporting and
    storing solid and liquid samples
    and reagents
    • The unit accommodates 24 tubes
    with 0.5 mL , 1.5 mL or 2.0 mL
    volumes.
    Laminar Air Flow
    • A laminar flow cabinet or
    tissue culture hood is a
    carefully enclosed bench
    designed to prevent
    contamination of biological
    samples, or any particle
    sensitive materials.
    • Due to the direction of air flow,
    the sample is protected from
    the user but the user is not
    protected from the sample.
