WebbPositive displacement Pipettes are ideally suited for solutions of very high, or very low viscosity, and can help confirm accurate pipetting of low volumes (1-10uL) by visual inspection. I regularly pipette volumes down to 2uL of stock standards in highly volatile solvents and quantitative accuracy is very high. Webb15 sep. 2024 · A sterile pipette is taken. 1 ml of properly mixed sample/culture is drawn into the pipette. The sample is then added to the first tube to make the total volume of 10 ml. This provides an initial dilution of 10 -1. The dilution is thoroughly mixed by emptying and filling the pipette several times.
