2 Volumetric flasks, BLAUBRAND®, class A, PUR Plastic coated

PURprotect, conformity certified. Boro 3.3. DIN EN ISO 1042. Calibrated to contain (TC, In). Ring mark and inscriptions in high contrast blue enamel. With PP stopper.
The plain and high quality PUR coating envelops the volumetric flasks like a protection skin. In the event of breakage, the safety coating helps contain the glass fragments. The light blue coating facilitates optical distinction. Suitable for dishwasher (cleaning up to max. 95°C). The maximum operating temperature at dry heat is 135°C (exposure time < 30 min). Frequent autoclaving at 121°C reduces splintering protection. On request, also available with individual certificate, USP individual certificate or DAkkS calibration certificate.
