NEW Volumetric flasks

NEW! Synthetic coating for better protection

Volumetric flasks, BLAUBRAND®, PURprotect, Class A

The PUR coating envelops the volumetric flasks like a protective skin.
In the event of glass breakage, the safety coating helps contain the glass fragments. Compared to uncoated glass flasks the electrostatic charge is not increased. The light blue coating facilitates optical distinction.
The maximum operating temperature at dry heat is 135°C (exposure time
< 30 min). Frequent autoclaving at 121 °C reduces splintering protection. Cleaning up to max. 95 °C.
