Volumetric flask, PMP, class B, with NS stopper, PP

Along with pipettes, volumetric flasks are the most accurate volume measuring tools in a modern laboratory. They do not have a system of graduated scale markings, but rather a single calibration mark that defines the calibrated volume exactly. 

Features

• crystal clear
• accurate volume measurement
• good chemical resistance 
• autoclavable
• UV resistant

The special manufacturing process developed by VITLAB, and the proven VITLAB quality management system, ensure compliance with and sometimes improvement of the volume tolerances specified by the standards. Light-sensitive substances require protection from the effects of light and particularly UV-light. Therefore, VITLAB developed the volumetric flasks VITLAB^® UV-protect manufactured from specially pigmented plastic. The special pigments safely protect samples from the effects of light, while maintaining high transparency to enable volumes to be set accurately.

Thermal stress up to 121 °C (autoclaving) does not permanently exceed the tolerance limit. To preserve markings, cleaning at no higher than 60 °C is recommended.

The tolerances are approx. 20% better than class B according to DIN EN ISO 1042, these flasks are more accurate than equivalent glass flasks. Trace-element contamination from virgin PMP is negligible. Individually ring-marked, per DIN 12664, supplied with standard NS polypropylene stoppers.

PMP (TPX) and PTFE are equally resistant to concentrated and even hot concentrated hydrofluoric acid. For chemical and physical resistance data see - General Technical Information Sheet

Class A certified are available, please see the products with a 'A' suffix. e.g. LCVV4-0025A.
