Achieve uncompromising liquid handling precision with the Heathrow Scientific Clear Volumetric Flasks (2306A Series). Manufactured from premium, low-expansion borosilicate glass, these heavy-duty laboratory flasks are engineered to provide maximum resistance to extreme thermal shock and harsh chemical corrosion. Designed specifically for critical analytical chemistry, titrations, and quantitative solution preparation, they are rigorously calibrated "To Contain" (TC) exact volumes of liquid at the industry-standard reference temperature of 20°C (68°F).
Every flask in the 2306A series strictly complies with ASTM E-288 Class A specifications and USP standards for quantitative laboratory glassware. To guarantee error-free readings, the meniscus graduation line is sharply defined and uniformly fired into the glass neck. Additionally, each flask includes a tight-sealing, precision-ground glass stopper to prevent sample evaporation and features a large, frosted marking square for permanent labeling.
