BLAUBRAND® volumetric instruments offer the best in technical perfection. n Adjustments carried out using computer-controlled production facilities. n Individually adjusted volumetric instruments, highest precision even for partial volumes. n AQL ≤ 0.4, i.e. the error limits are met with a reliability of at least 99.6 %. n Long service life through the use of high quality blanks and printing colors. n No permanent volume changes after heating, up to 250 °C. n Lot certificate supplied, and USP or DAkkS calibration certificate available upon request.

BLAUBRAND ® volumetric instruments Reliability for your analyses Blanks Quality management Thermal stress in the glass blanks are eliminated prior to adjustment.This results in optimum mechanical stability, a requirement for keeping the volume constant despite any subsequent thermal load. The combination of process monitoring and random checks establishes an acceptable quality level (AQL) of at least 0.4 This means that the specified error limits are met with a statistical certainty of at least 99.6%. Reference temperature Every glass volumetric instrument is individually calibrated. For measuring...
