Fabricated from premium Type I, Class A borosilicate glass, these plain-neck tubes deliver exceptional thermal shock resistance and superior chemical durability against aggressive acids, alkalis, and organic extraction solvents. Featuring a uniform wall thickness distribution that handles physical centrifugation forces and thermal expansion, the round-bottom geometry is structurally optimized to clear out sedimentations and maximize sample recovery during chemical assays. The plain, beadless rim accepts standard laboratory closures, plastic caps, or plug stoppers for seamless workflow adaptability.\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 Type I Class A Borosilicate Matrix:\u003c\/b\u003e Manufactured from high-purity borosilicate glass with a low coefficient of thermal expansion.
