the basic theory driving pipetting requires making a vacuum to attract up and launch a specified volume of liquid. There are 2 key techniques: air displacement and positive displacement.
when you finally lessen the measurements to under ten, you enhance the prospect you may have a end result that is certainly beyond the specification. one particular should get this possibility into account When selecting involving four or ten measurements.
