Volumetric flasks with 3-marks for a quick and easy function check of your bottletop dispenser! The mark in the middle shows the nominal volume; the upper and lower marks show the specified error limits. If the meniscus of the dispensed nominal volume falls between the upper and lower error limits, the dispenser is functioning correctly. If the dispensed volume exceeds the error limits after repeated measurements, the dispenser is out of specification.

The function test is meant to be a quick check only and does not replace regular gravimetric testing of liquid handling instruments according to ISO 8655.

Class A, DAkkS calibrated (certificate included).
