Centrifugation
Centrifugation. One of the most common pieces of equipment used to separate materials into subfractions in a biochemistry lab is the centrifuge. A centrifuge is a device that spins liquid samples at high speeds and thus creates a strong centripetal force causing the denser materials to travel towards the bottom of the centrifuge tube more rapidly than they would under the force of normal gravity.

CHAPTER 2-1 | Lab bench Setup
The principles of the dissecting microscope are the same as those for the compound microscope, but this microscope will always have two oculars, and lighting will usually be from above, giving you reflected light. Some microscopes have a light in the base, but I (Glime) find these uncomfortable to work with because they make the stage high (Figure 8) and I cannot rest my hands on the lab bench.
