Designed for vacuum filtration of corrosive liquids for analysis of particulate contamination.

Unique base design has integral vacuum connection located above filtrate drip to prevent contamination of vacuum line with filtrate droplets.

Unit consists of a 300 ml funnel; a coarse-porosity, fritted-glass filter support base with integral vacuum connection; and a 1 L inner joint flask. An aluminum clamp connects funnel and support base. [ST] joints are 40/35.

Liquids come in contact only with borosilicate glass.
