3. Laboratory Equipment Autoclave
Chamber that uses high levels of heat and pressure to sterilize instruments and materials
Destroys harmful organisms and pathogens
One of the simplest looks a great deal like a pressure cooker. It is a large pot with a gauge on top and bolts that fasten the top to the pot.
The idea behind this is that water inside a pressurized container can be heated above the boiling point. It will only reach 212°F (100°C) in an open container. However, in a pressurized autoclave, the water will reach much higher temperatures.

4. Laboratory Equipment Centrifuge
instrument used to isolate solids (in the form of a small pellet) from a solution.
This is done by spinning closed containers of the mixture very quickly around a fixed, central point. The centrifugal force generated by this motion forces the denser material in the suspension against the walls of the container
a. Utilizes very small tubes to hold solution.

5. Laboratory Equipment Micropipette
instrument used to measure and extract very small amounts of liquid from a solution.
a. Different versions measure to different levels of accuracy, but usually to the nearest uL (micro Liter).
b. Often used to hand small amounts of solution needed in DNA labs.

6. Laboratory Equipment Compound Light Microscope
the most common and versatile microscope in agricultural research labs.
a. Uses a light source in combination with a variety of lenses to magnify images usually up to no more than 200x.

7. Laboratory Equipment Incubator
sealed chamber with controls to manage temperature (and sometimes humidity)- used for the culture of microorganisms.

8. Laboratory Equipment Water Bath
vessel that uses water to heat or maintain a constant temperature of laboratory materials or equipment
Often used to heat or thaw fragile biological substances including semen

9. Laboratory Equipment Hot Plate
instrument that applies direct heat to glassware containing laboratory solutions.
Coil models (like stove tops) are dangerous-
newer models have ceramic tops and often integrated magnetic stirrers.

10. Laboratory Equipment Petri Dish
type of glass or plastic shallow round dish with a close fitting lid
most well known for holding a culture medium upon which cells, bacteria, and viruses can be grown and studied

11. Laboratory Equipment Agarose Gel – Agar
a substance that is used in science for gel electrophoresis
The medium is composed of a purified agarose powder that has been boiled in a buffer solution and then cooled into a gel.

12. Laboratory Equipment Graduated Cylinder
a measuring instrument for measuring fluid volume; a glass container (cup or cylinder or flask) whose sides are marked with or divided into amounts

13. Laboratory Equipment Shaker
used to mix or agitate small volumes of solution, often prior to placement in a centrifuge.

14. Laboratory Equipment Gel Electrophoresis Chamber
During DNA electrophoresis DNA and restriction enzymes are inserted into the wells of a agarose gel.
The agarose gel is then placed into a electrophoresis chamber along with a buffer (the buffer keeps the DNA fragments soluble in water). The electrophoresis chamber has a electrical charge running through it that carries the DNA fragments through the gel

15. Laboratory Equipment Gel Electrophoresis Power Source
The actual power source that sends an electric charge through the chamber, causing the DNA to run and break into smaller visible fragments

16. Laboratory Equipment White Light Box
A UV light box that is used under a DNA gel in order to better determine and detect DNA fragments

17. Laboratory Equipment Centrifuge Tubes
A tapered and specially-engineered test tube specifically for centrifuge work, designed to resist the high G-forces induced by the centrifugal forces.
They are mainly used in medical work to centrifuge human blood for test purposes

18. Laboratory Equipment Pipette Tips
Disposable tips used to protect the micropipetter from contamination
These tips are used and disposed of after EACH use in order to prevent contamination and reduce clean up and sterilization

19. Laboratory Equipment Inoculating Tube – Loop
is a simple tool used mainly by microbiologists to retrieve an inoculum from a culture of microorganisms. The loop is used in the cultivation of microbes on plates by transferring inoculum for streaking.

20. Laboratory Equipment DNA Loading Dye
First, loading dye is meant to help weigh down the DNA, so that it can sink into the bottom of the wells and not float in the buffer solution
loading dye moves more quickly than the actual DNA parts so it is an indicator to when to turn off the power on the electrophoresis chamber
The dye also makes the DNA visible to the naked eye, giving it a purplish color, and making it easier to work with.

21. Biotechnology – Lab Equipment
10.02: Demonstrate approved safety practices while conducting scientific experiments in a biotechnology laboratory.

22. Use of Laboratory Equipment
1. A graduated cylinder is used to measure the volume of liquids. Readings should always be taken at the MENISCUS, at the lowest part of the curve.
2. When using a water bath to thaw semen straws, the bath should be heated to 99° F and the straws submersed for 45 seconds immediately upon removal from the storage tank.

23. Use of Laboratory Equipment
3. To avoid air bubbles and extract the correct amount of solution utilizing a micropipette, the tip must be completely submerged in the solution.
4. Proper use of a centrifuge requires that the instrument be balanced. This can be accomplished by placing and equal number of tubes directly across from each other in the instrument.

24. Laboratory Equipment Safety
1. Check all gauges & valves before using an autoclave. Never leave equipment unattended while running, as high temperatures and pressure can be dangerous.
2. When culturing bacteria, it is important that the incubator remains closed, and the plates tightly sealed.

25. Biotechnology – Lab Equipment
