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.

4. Lab equipment Lab. equipment refers to the various tools used by scientists working in a laboratory.

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

6. Types of microscopes Simple Compound Electron

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   (CO 2 ) 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. 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.

13. Lab. refrigerator

14. Centrifuge is an apparatus that rotates at high speed  and separates substances of different densities.

15. Balance used to measure an object’s mass to a very high degree of precision.

16. hot plate / stir plate used to heat and stir substances. Magnetic stirring bars

17. Water bath   is a device that maintains water at a constant temperature. It is used in the microbiological laboratory for incubations.

18. Biological Safety Cabinets    is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with  pathogens .

19. Bunsen burner  is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating and sterilization .

20. 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 .

21.   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.

22. 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.

23. 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.

24. slide and coverslip

25. 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

26.    Glassware Pipet and Graduated Cylinders Glass or plastic Used to measure liquid volume. Graduated in ml.

27. Graduated Cylinders Pipet

28. Glassware Beaker Glass or plastic Used to stir, heat(if glass) and measure liquid volume in ml.

29. Glassware Flask Glassware used to heat and store substances.

30. Glassware Funnel aids in pouring liquids into small openings without spilling them.

31. Glassware Test tube used to mix, heat or store substances. Test tube rack used to hold test tubes.

32.   wash Bottles used to rinse various pieces of laboratory glassware.

33. Filter paper special paper used to separate solids from liquids.
