BOROSILICATE GLASS REAGENT BOTTLE 250ML WITH GROUND GLASS STOPPER
The Apex Labs Borosilicate Glass Reagent Bottle 250ml with Stopper is an indispensable laboratory container designed for storing, mixing, and dispensing chemical reagents, biological media, and acid solutions.
Because chemical stability is essential in analytical procedures, this reagent bottle is crafted from high-grade 3.3 expansion borosilicate glass. Consequently, it offers exceptional resistance to aggressive thermal shock, strong acids, and organic solvents.
Furthermore, each 250 mL bottle features an interchangeable, precision ground-glass stopper. As a result, it forms an airtight seal that prevents chemical evaporation, contamination, and volatile gas leakage during long-term storage.
B2B Procurement & GeM Supply: Apex Labs supplies high-purity laboratory glassware with complete GST tax invoices, enabling institutional buyers to claim full Input Tax Credit (ITC).
Additionally, central universities, research facilities, and government laboratories can order directly via our active vendor profile on the Government e-Marketplace (GeM) portal.
