Highest precision in volume measuring devices
Volumetric measurement is a routine operation in the laboratory. Therefore, volumetric instruments such as volumetric flasks, graduated cylinders and pipettes are standard equipment in every analytical laboratory.
The importance of the degree of measurement accuracy in laboratory routines cannot be overstated. VITLAB® has decades of experience in the development and production of laboratory products which are used to measure volumes.
Based on DIN 12681 – which incidentally was established through the initiation of VITLAB® – VITLAB® was the first manufacturer to make Class A, conformity-certified measuring cylinders available in PMP plastic.
All Class A PMP volumetric flasks are optionally available in transparent or UV absorbing variations for light-sensitive substances.
Calibration
Type 'TD, Ex': The delivered quantity of liquid corresponds exactly to the capacity indicated on the instrument (pipettes and burettes).
Type 'TC, In': The contained quantity of liquid corresponds exactly to the capacity indicated on the instrument (graduated cylinders and volumetric flasks).
VITLAB® adjusts each individual volumetric flask at a room temperature of 20 °C. Due to the hydrophobic characteristics of the materials, VITLAB® plastic volumetric instruments can assure that the measured liquid quantity (In) is the same as the removed quantity (Ex) for aqueous solutions.
Accuracy classes
Class A: the tolerances lie within the levels dictated by DIN and ISO.
Class B: the tolerances are twice the margins of error for Class A dictated by DIN and ISO.
Detailed explanations on “accuracy in volume measurement” are available in the chapter on “Technical Information”.
Conformity
VITLAB® guarantees that the measuring devices are calibrated in accordance with the German Calibration Regulations.
The special manufacturing process, developed by VITLAB®, and the proven VITLAB® quality management system ensure that the tightest tolerances for the adherence to measurement standards are maintained.
