New volumetric flask, low-actinic red, 250 ml 'a' pyrex


A new, top-quality Pyrex flask. Includes the original unused Corning #16 ruby red barrel stopper. A beautiful piece of glassware. No chips or cracks.
Strict class A tolerance. Calibrated to contain (TC @20C). The coloration filters out UV light, as well as most light below 500nm. This protective color is an integral part of the glass - all of the quality aspects expected from a Pyrex brand flask are retained.
~225 mm (with stopper), ~255 mm (without) x ~78 mm
$306-$321, for packs of 6 (mfr. and large lab supply house prices).
