Below is a list of Pipette Calibration manufacturers from Rockville, Maryland. Pipette calibration is a process through which a pipette is evaluated to determine its actual capacity. A pipette is used in medical tests and molecular biology to hold and dispense measured amounts of liquid. They are the most commonly used instruments in many laboratories; as such, their precision and accuracy is central for dispensing, dilution and assay results. The performance of a pipette has direct results when generating data because the amount of liquid held in the pipette and then dispensed affects the solution.
