Low actinic volumetric flasks, [ST] stopper, class A, PYREX®
Flasks are for use with light sensitive materials.
All flasks are graduated to Class A volumetric tolerances and calibrated to meet ASTM specifications E-694, E-542, and E-288. Certified flasks are individually serialised and supplied with NIST-traceable Certificate of Identification and Capacity.
PYREX® Serialised/Certified Volumetric Glassware is now tested and calibrated in an ISO/IEC 17025 certified laboratory.
The low actinic, red colour is an integral part of the flask, which retains the mechanical strength, chemical stability, and thermal resistance of PYREX brand labware, while protecting light-sensitive materials. Graduation line is sharp and permanent and inscription of large white block letters is easy to read. Stoppers are also made of low actinic glass.
