Measuring 20 mm Outside Diameter (OD) by 150 mm in length with a total working capacity of 30 mL, these large-volume tubes are precision-engineered from high-purity Type I, Class B borosilicate glass. This premium glass matrix delivers outstanding thermal shock resistance and superior chemical durability against aggressive acids, alkalis, and organic extraction solvents. Outfitted with an 18-415 GPI thread profile, they are designed to couple seamlessly with reusable phenolic or polypropylene screw caps to establish a vapor-tight mechanical seal. This makes them a reliable choice for tissue cultures, chemical synthesis, centrifugation, and biological sample archiving.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePremium Type I Class B Borosilicate Glass:\u003c\/b\u003e Conforms strictly to USP Type I and ASTM E438, Type I, Class B specifications.
