Could your lab use a more reliable and cost effective solution to sample preparation? Traditional air displacement pipettes are susceptible to variations in atmospheric pressure, viscosity, vapor pressure, etc. Class A glassware is labor intensive and wasteful. The Microlab 600 is the answer to these problems. Positive Displacement vs. Air Displacement The Microlab 600 is completely primed with liquid making it a positive displacement system. The liquid is not compressible, so each time the syringe aspirates or dispenses, the liquid is accurately measured. Air displacement systems trap compressible air in the fluid path. When liquid is moved this air is compressed, causing results that vary with atmospheric conditions, sample viscosity and the operator?s technique.
