BLAUBRAND® volumetric flask in amber borosilicate glass 3.3 is a Class A measuring flask intended for accurate volumetric preparation in analytical laboratories. Offering a nominal capacity of 250 ml and a standard ground joint NS 14/23, this white-graduated flask is well suited to making up and diluting light-sensitive reagents and standard solutions. Constructed from chemically resistant Boro 3.3 glass and completed with a matching glass stopper, it delivers dependable sealing and robust day-to-day performance. The amber body reduces light exposure to sensitive contents, while Class A accuracy with DE-M marking and an ISO individual certificate support traceable volume control. This single-piece unit from manufacturer Brand fits pharmaceutical, environmental, food-testing and general chemistry applications that rely on calibrated volumetric glassware. White graduation marks improve legibility against the brown glass, and the NS joint works with the included stopper for secure closure during mixing or brief storage. The flask is supplied non-sterile for laboratory use where consistent Class A volumetric accuracy is required.

Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
