  • ComicstreamerA pipette is very precise, meaning it measures accurately to a small measurement (microlitres or less). Accuracy describes how closely to the exact amount something will measure, could be 1,000 litres or a millilitre, if you apparatus measure 1,000 litres as 999 litres its 99.9% accurate but has a precision of 1 litre. ,The two classes differ in the accuracy of measurement with a Class A/AS being the highest accuracy, and Class B accuracy tolerances being twice those of Class A/AS. Class AS products are calibrated to the same high tolerances as ClassA, but are designed to permit more rapid outflow of the liquid in burettes and pipettes.
