Improve pipetting of Viscous Liquids in Pharmaceutical Formulations
Bubble-free and accurate pipetting with positive displacement pipettes
Whilst commonly used air displacement pipettes are highly accurate for most liquid dispensing applications, the viscosity, volatility, surface tension and temperature of the solution can adversely affect their performance. In pharmaceutical formulations, frequently used liquids, like glycerol, are much more viscous than water and leave residue in the tip when dispensing, thereby decreasing accuracy.
Working like a syringe, the tips of a positive displacement pipette eliminate the air cushion between the sample and disposable piston. Therefore, the accuracy of the pipette is not affected by the physical properties of the sample (e.g. viscosity and temperature).
This document demonstrates the advantages of using positive displacement pipettes over air displacement pipettes in pharmaceutical formulations requiring accurate and precise pipetting of viscous liquids.

Topic world Pipetting
Pipetting is one of the most basic yet critical techniques in the laboratory. It enables the precise and controlled transfer of liquids, which is essential for accurate measurements and reliable results. Whether in DNA analysis, cell culture or biochemical assays, correct pipetting significantly influences the quality of the results.
