Molded from optically clear, shatter-resistant polycarbonate, this flask provides a robust alternative to fragile glass laboratory ware. A defining feature of this specific model is its baffled bottom geometry, which dramatically increases hydrodynamic agitation and oxygen transfer when placed on an orbital shaker incubator. Equipped with the proprietary DuoCAP system, this sterile, single-use flask allows researchers to seamlessly transition between vented gas exchange and a completely sealed anaerobic environment using a single closure mechanism.\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\u003eBaffled Bottom Geometry:\u003c\/b\u003e The molded internal baffles disrupt laminar fluid flow during orbital shaking.
