2. What Is a Laboratory?
• A laboratory is a room or a place equipped for
the performance of tests, experimentation,
investigative processes .
3. Medical laboratory
• A medical laboratory or clinical laboratory is
a laboratory where tests are done on clinical
specimens in order to get information about
the health of a patient as pertaining to the
diagnosis, treatment, and prevention of
disease.
5. Microscopy
What is a microscope?
• Is an optical instrument consisting of a combination
of lenses which magnifies the image of the object
seen through it.
• It is used for the morphological study of a very small
organisms which are not visible by naked eye.
Micro= small scope=to view
7. Incubator
• Is a device used to grow and maintain microbiological
cultures.
• The incubator maintains optimal temperature,
humidity and other conditions such as the carbon
dioxide (CO2) and oxygen content of the atmosphere
inside.
9. Autoclave
• An autoclave is a pressure chamber used
to sterilize equipment and supplies by subjecting
them to high pressure saturated steam at 121 °C for
around 15–20 minutes depending on the size of the
load and the contents.
• Used to sterilize culture media, discard, and other
equipments.
11. Oven
• device used in sterilization.
• oven uses dry heat to sterilize.
• It used to sterilize items that might be damaged by
moist heat (e.g., glasswares, powders, oils).
12.
13. Laboratory refrigerator
Is used for a wide variety of purposes such as:
• maintenance and storage of stock culture between
subculturing periods.
• storage of sterile media to prevent dehydration.
• also used as repository for thermolable solutions, antibiotics
and serums.
15. Centrifuge
• is an apparatus that rotates at high speed
and separates substances of different densities.
16.
17. Balance
• used to measure an object’s mass to a very high
degree of precision.
18. hot plate / stir plate
• used to heat and stir substances.
Magnetic stirring bars
19. Water bath
• is a device that maintains water at a constant
temperature.
• It is used in the microbiological laboratory for
incubations.
20. Biological Safety Cabinets
• is an enclosed, ventilated laboratory workspace for
safely working with materials contaminated
with pathogens.

22. Bunsen burner
is a common piece of laboratory equipment that
produces a single open gas flame, which is used for
heating and sterilization.
23. Inoculating loops and needles
• Inoculating loops are used to transfer microorganisms to
growth media or for staining slides.
• The wire forms a small loop with a diameter of about 5 mm.
• The loop of wire at the tip may be made
of platinum or nichrome.
24. • Needles are straight wires (no loop) used to pick up
bacteria from closely packed colonies or to inoculate
in a very defined area.
• needles commonly used to inoculate semi-soft
media.
25.
26. Anaerobic jar
• is an instrument used in the production of an
anaerobic environment.
• This method of anaerobiosis is used to culture
bacteria which die or fail to grow in presence
of oxygen.

28. Glassware
Glass slide and cover slip
• Glass slide:
used to place specimens on to observe under the microscope.
• Cover slip:
used to cover specimens on a microscope slide.
30. Glassware
Petri dishes
• often used to make agar plates for microbiology studies.
• The dish is partially filled with warm liquid containing agar and a mixture of
specific ingredients that may include:
• nutrients
• blood
• salts
• Carbohydrates
• dyes
• indicators
• amino acids
or
• antibiotics
31. Glassware
• Pipet and Graduated Cylinders
• Glass or plastic
• Used to measure liquid volume.
• Graduated in ml.
