Graduated flasks
Volumetric flasks provide precise results in chemistry and pharmacy. They are not scaled, but have a single ring mark that is drawn all the way round the neck to avoid reading errors.
The narrow neck results in high setting accuracy. In addition, volumetric flasks have bulbous curves in the upper area so that any gas bubbles that form can escape from the solution more easily. However, if there are gas bubbles in the solution, the volumetric flask must be swivelled slightly so that the bubbles rise to the top. In addition to volumetric pipettes and burettes, volumetric flasks are therefore the most accurate volumetric instruments in the laboratory for analysis.

Measuring cylinders, PMP, tall form, class A, blue graduations
Clear. Exposure to temperatures up to 121 ºC (autoclaving) will not cause permanently exceeded error limits. Cleaning at temperatures below 60°C is recommended to preserve graduations and inscriptions. Class A tolerance is not affected even after 20 washes and 10 autoclave treatments. (DIN 12681 requires: 10 washes and 3 autoclave treatments). Supplied with batch number and one batch certificate per packing unit. On request, they are also available with an individual certificate, USP individual certificate or DAkkS calibration certificate. Batch and individual certificates can also be downloaded at the supplier"s website....
Volumetric flasks VITLAB® UV-protect, PMP, Class A with NS stoppers, PP
UV-absorbing, highly transparent.
For storage of light-sensitive substances.
With ring mark individually calibrated to In".
Class A tolerances according to DIN EN ISO 1042.
With printed lot number and batch certificate. Thermal stress up to 121ºC (autoclaving) does not permanently exceed the tolerance limit. To preserve markings, do not clean at temperatures exceeding 60ºC...
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...
