Pipettes are used for precise measurement of liquids. Only certain quantities can be filled with bulb pipettes. Adjustment is made to drain ("Ex") for + 20 °C reference temperature. The tolerances for the volume content of calibratable pipettes correspond to the error limits of the German weights and measures regulations as well as ISO and DIN. The pipettes are made of soda-lime glass and comply with Class AS. The scale is printed in amber. Pipettes with a batch number and accuracy Class AS are supplied with a batch certificate. This certificate documents the mean value obtained from measuring the batch in question, the standard deviation and the day of issue. The batch certificates can also be retrieved online. The batch number consists of four digits. The first two numbers specify the production year, and the following two numbers specify the batch, e.g.: 18.01.

• Complies with ISO 648
• Manufactured from soda-lime glass
• The blow-out allows different quantities of liquids to be held and dispensed in portions of the same size
• The rapid discharge reduces significantly the waiting time compared to Class A
• Calibration is based on the poured out volume (“Ex”) at a + 20 °C reference temperature
• The volume content tolerances conform to accuracy Class AS
