The document outlines various types of microbiological equipment used in laboratories, detailing their functions and purposes. Equipment such as air samplers, analytical balances, autoclaves, and incubators are highlighted for their roles in analyzing samples, sterilizing materials, and maintaining optimal growth conditions for cultures. Other tools like centrifuges, micropipettes, and PCR machines enhance the precision and efficiency of experiments and analyses in microbiology.

1. MICROBIOLOGICA
L EQUIPMENT IN
THE LABORATORY

2. AIR SAMPLER
• a device that
collects air samples
for analysis. Air
samplers are used
to measure the
concentration of
airborne particles,
such as dust,
chemicals, and
microorganisms

3. Analytical balances are precision measuring instruments used
in quantitative chemical analysis, to determine the mass of
solid objects, liquids, powders and granular substances.

4. Autoclaves operate at high temperature & pressure in
order to kill microorganisms & spores
- it is used to decontaminate certain biological waste
and sterilize media, instruments and lab ware.

5. BIOCHEMICAL MEDIA
• used to identify and
study microorganisms by
observing their
biochemical properties
• used to detect
microorganisms, identify
bacterial species, and
understand the severity
of bacterial infections

6. Bunsen burner is a kind of ambient air gas burner that produces a single open gas flame, and is used for heating, sterilization, and combustion

7. Centrifuge is a laboratory device that is used for the
separation of fluids, gas or liquid, based on density

8. COLONY COUNTER
• counts colonies of
microorganisms on a plate,
such as a Petri dish, slide, or
agar plate
• used in microbiology
laboratories to count and track
the growth of bacteria and
fungi

9. Deep Freezer is a piece of laboratory equipment designed to preserve medical samples, medicines, and more for
extended periods

10. DRYING OVEN
• to remove moisture
from materials by
circulating heated air
• are used for drying
materials,
sterilization,
temperature testing,
incubation & welding
electrode drying

11. Heating mantles are used for heating or tempering
organic liquids placed in reaction kettles, round-bottomed
flasks, or relevant reaction vessels required for the
boiling, evaporation, distillation, or extraction process

12. Heating plates are often used in the
laboratory to perform chemical reactions, heat
samples, and for numerous other tasks

13. HOMOGENIZER
• a mechanical device that
mixes, breaks down, or
disperses materials to
create a uniform mixture.
Homogenizers are used in
many industries, including
food, beverage, chemical,
and pharmaceutical.

14. Incubator is a device used to grow and maintain microbiological cultures or cell cultures
- it maintains optimal temperature, humidity and other conditions such as the CO2 and
oxygen content of the atmosphere inside

15. Laminar airflow is used to separate volumes of
air, or prevent airborne contaminants from entering
an area
- used to exclude contaminants from sensitive
processes in science, electronics and medicine
- also known as BIOSAFETY CABINET

17. MAGNETIC STIRRER
• stirs liquids by
spinning a stir bar
immersed in the
liquid. It's used in
chemistry and
biology to mix
solutions, ensure
consistency, and
control
temperature

18. Micropipette is a common laboratory instrument used
to measure small amounts of liquids with a volume range
between 1 and 1000µl
- It is also used to transfer a precise amount of fluid
from one container to another

19. PCR MACHINES
• also known as a thermal
cycler
• it amplifies DNA and
RNA samples through a
process called the
polymerase chain
reaction (PCR)

20. Petri dish is used to culture different types of cells,
including bacteria and molds
- It often contains a nutritional medium on
which the cells can grow

21. Petri Dish Rotator is a fixed-angle, multi-function
3D rotator providing all that is required (rotation,
reciprocation and vibration) to fully optimize the
mixing of different sized particles in flasks, dishes,
petri dishes and boxes

22. • measures the acidity or
alkalinity of a solution, or its
pH level
• measures the difference in
electrical potential between
a pH electrode and a
reference electrode
pH meter

23. TEST TUBES
• to hold, mix, and heat small
amounts of liquids and
solids for experiments and
analysis
• also used to collect
biological samples

24. Water bath is used to incubate samples at a constant temperature
over a long period of time & a preferred heat source for heating
flammable chemicals instead of an open flame to prevent ignition

25. Water distiller is a machine that purifies water by removing more
than 99.9% of contaminants, including chemicals, heavy metals,
microorganisms and sediment

26. Vortex mixer is a simple device used commonly in laboratories to mix small vials of liquid
- It consists of an electric motor with the drive shaft oriented vertically and attached to a
cupped rubber piece mounted slightly off-center
