BLAUBRAND(BRAND) 37245 20ml Volumetric Flask Class a DE-M Boro 3.3 0.06ml Error with PP/PE Stopper ISO Batch Certificate-Labcan Scientific

Product Description

The BRAND BLAUBRAND 37245 20ml Class A Volumetric Flask is a precision-engineered volumetric instrument developed by Germany's BRAND GMBH specifically for high-accuracy small-volume quantitative liquid handling.

Crafted from high-purity Borosilicate Glass 3.3, this flask features an exceptionally low coefficient of thermal expansion and outstanding resistance against strong acids, bases, and aggressive organic solvents. Each unit is individually calibrated "to contain" (TC, In) at a reference temperature of +20°C using automated calibration systems. The 20ml capacity features an ultra-precise error limit of ±0.06 ml and bears the official German DE-M conformity mark.

The flask comes fitted with a blue polypropylene/polyethylene (PP/PE) ergonomic square stopper. Its anti-roll design prevents accidental rolling off laboratory workbenches, while the integrated dripping tip allows liquid droplets to drain back cleanly. Inscriptions and the ring mark are applied in heat-fused, high-contrast blue enamel that resists aggressive chemical cleaning agents and repetitive autoclave sterilization.

Supplied complete with an official ISO batch certificate specifying batch mean values and standard deviations, the BLAUBRAND 37245 supports seamless measurement traceability and audit readiness under ISO/IEC 17025, GLP, and GMP frameworks.
