Product Description
Prepare light-sensitive standards to Class A accuracy without wrapping flasks in foil. Amber RAY-SORB processing filters out short-wavelength light that can degrade photosensitive compounds, so vitamins, pharmaceuticals and dyes stay stable while you dilute to the mark and work through your analysis.
This listing is for Kimble catalog number 28016-25: RAY-SORB Volumetric Flask, Class A, with Color-Coded PTFE Stopper, 25 mL, Case of 12. These flasks are borosilicate glass 3.3 with an external amber coloration, meeting ASTM E288, Class A unserialized requirements. Each is calibrated to contain, includes a marking spot and comes with a standard taper PTFE stopper whose handle is color coded by size. Capacities range from 10 mL to 1000 mL. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
