Molded from premium-grade PYREX low-expansion Type I borosilicate glass, this narrow-mouth flask offers exceptional thermal shock resistance and superior chemical durability against aggressive acids, alkalis, and organic solvents. Featuring a classic conical body geometry that maximizes interior mixing space while restricting evaporation, it is outfitted with a heavy-duty reinforced rim structure designed to resist physical chipping or mechanical impacts. The exterior wall incorporates high-contrast, permanent white enamel graduation markings alongside an oversized matte marking spot to ensure effortless sample identification and tracking.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePremium PYREX Borosilicate Composition:\u003c\/b\u003e Fabricated from Type I Class A borosilicate glass.
