250ml Volumetric flasks boro 3.3 class A PUR coated blue graduations

Volumetric flasks, boro 3.3, class A, PUR coated, blue graduations
The plain and high quality PUR coating envelops the volumetric flasks like a protective skin. In the event of breakage, the safety coating helps contain the glass fragments. The light blue coating facilitates optical distinction. Frequent autoclaving at 121 °C reduces splintering protection. Suitable for dishwashers (cleaning up to max. 95°C). All Blaubrand® volumetric flasks are supplied with a batch number and an accompanying batch certificate within the outer packaging. They are also available with individual works or DAkkS (former DKD) calibration certificate on request.
