Product Description
Light-sensitive standards and reagents can degrade before you finish an analysis. These amber volumetric flasks filter the wavelengths that cause photodegradation, so you can prepare and hold sensitive solutions with Class A precision and less worry about breakdown on the bench. They are well suited to pharmaceutical, vitamin and HPLC standard work.
This listing is for catalog number 2307A-1000: Volumetric Flask, Amber, Class A, Glass Stopper, 1000 mL, Pack of 2. Each flask is machine-blown from low-actinic amber borosilicate glass and finished with a heavy-beaded neck tooled for a standard taper glass stopper. Flasks are calibrated to contain at 20°C, with a sharply defined fill line and a large marking square. Capacities range from 10 mL to 1000 mL, each supplied with its stopper. Add it to your LIGHT LABS order and keep your lab stocked.
