Constructed of non-metallic materials
• Filters quickly and simply, 3 times faster than the gravity method • Filtrate is collected directly in a beaker, eliminating transfers • Filter domes are constructed of borosilicate glass and polypropylene, virtually eliminating chances of trace metal contamination • Designed for direct filtration and for use where transfers should be avoided • Several units may be connected in a series and vacuum applied from a single source • Upper portion of dome is tooled to accept a # 8 stopper and the popular 47 and 90 mm funnel support filtration assemblies • Valve and hose connections are made of CTFE; O-rings are FKM • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
