The recently published standard DIN EN ISO 835 replaces the previous DIN 12 697. This new standard reduces the waiting time for graduated pipettes from 15 to 5 seconds for the type 2 pipettes and includes the functions of total delivery and nominal volume at top. We recommend the graduated pipette type 2 with complete delivery also at partial volumes, because the meniscus needs to be set only one time to achieve exact pipetting. In contrast, with types 1 and 3, there is a risk of over-dispensing while setting the meniscus the second time. In such a case, the sample would have to be prepared again. All BLAUBRAND® graduated pipettes are supplied with a batch number and an accompanying batch certificate in the original packaging. Upon request, they are also available with an individual certificate, USP individual certificate or DKD calibration certificate.
