Safeguard your light-sensitive chemical standards and biological samples while maintaining uncompromising volumetric precision with the Heathrow Scientific Amber Volumetric Flasks (2307A Series). Manufactured from premium, low-expansion borosilicate glass, these highly durable laboratory flasks are saturated with a low-actinic amber tint designed specifically to block UV and visible light degradation.
Engineered to meet the stringent requirements of rigorous analytical environments, every flask in the 2307A series complies fully with ASTM E-288 Class A specifications and USP standards for quantitative laboratory glassware. They are precisely calibrated "To Contain" (TC) exact volumes of liquid at the industry-standard 20°C (68°F), featuring a sharply defined, uniform graduation ring for error-free meniscus visualization. Each flask includes a tight-fitting ground glass stopper to prevent sample evaporation and features a large, frosted marking square for permanent labeling.
