Advanced Instruments Model 3W2 Osmometer– Wide range

DESCRIPTION

Advanced Osmometers are used to precisely measure the osmotic concentration of body fluids. Advanced Osmometers can also be used to determine the osmolality of other aqueous solutions with freezing points between 0 and -6 ° C. Some examples of such solutions are parenteral infusion solutions, laboratory solutions and fixatives, laboratory control solutions, corn sweeteners, milk, ice cream and dairy mixes, etc. Applications information is available upon request from Advanced Instruments Inc.
