Measuring Pipette, from Soda-lime Glass, Class B, Type 3 amber diffusion print

Pipettes are used for precise measurement and decanting of liquids. Graduated pipettes allow different amounts of liquid to be absorbed and dispensed in the same or in different sizes. 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 B. The scale is amber and the numbering takes place from top to bottom.
