Molded from crystal-clear virgin polystyrene (PS), this 250 mL vessel features Corning's low-profile \"Easy-Grip\" side indentations, providing technicians with a secure, slip-free handhold during wet-bench procedures and hood manipulations. The bottle is fitted with an orange, heavy-duty 45 mm high-density polyethylene (HDPE) plug seal screw cap that establishes a leak-proof hermetic barrier against environmental contaminants and ambient evaporation. Engineered with high-contrast, molded-in volumetric graduations and a standard 45 mm wide-mouth neck thread, this sterile container serves as both a standalone media storage bottle and a direct receiver flask for 45 mm bottle-top vacuum filtration units.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Structural Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eErgonomic Easy-Grip Sidewall Indentations:\u003c\/b\u003e Designed with contoured, recessed side channels that fit comfortably in hand.
