'''Vortex Mixers''' are used in the laboratory to mix materials contained in test tubes.  The force of the mixing is adjustable, and the mixer can be set to run only when a tube is inserted into the mixer receptacle.  The force of the mixer should be set so that the liquid in the tube forms a vortex as it mixes, and the tube containing the liquid should always be pointed away from you or your lab partner.  If a tube is more than 2/3 full, a vortex mixer should not be used because the liquid will splatter out of the tube.

'''Centrifuges''' are instruments that use centrifugal force to separate biological materials.  You will be using several types of centrifuges this semester.  Clinical centrifuges are bench top models that accommodate various sizes of centrifuge tubes depending upon the type of holder installed.  Refrigerated centrifuges are used when it is necessary to maintain the biological material at a constant cool temperature and can also accommodate several sizes of tubes.  Microcentrifuges are used for very small plastic centrifuge tubes called microfuge tubes.  All centrifuges require that the centrifuge tube containing the biological material be placed across from a tube of the same weight.  We call this “balancing the centrifuge.”  Tubes cannot be balanced by filling them to equal volumes, as these may not have the same weight.  They must be balanced by weight, using a scale.
