Eisco Labs: Filtration Assembly - 1000ml Flask, 300ml Funnel, 47mm Vacuum Base

Filtration Assembly, 1000 mL Flask, 300 mL Funnel, 47 mm Vacuum Base

This vacuum filtration assembly includes four pieces: a 1000 mL borosilicate flask, a 300 mL funnel, a 47 mm vacuum base with a sintered disk, and a 47 mm aluminum clamp. The sintered disk is G2 porosity, with a 40–90 micron range. Official copy lists an effective filtration area of 9.6 cm² and describes the unit as designed to maximize flow and reduce foaming. It is used for vacuum filtration of tissue-culture media, biological fluids, HPLC, and other aqueous solutions. Assembled, the set measures 17.25" tall and 8" wide and long.

What’s Included?

• 1000 mL borosilicate flask.
• 300 mL funnel.
• 47 mm vacuum base with a G2 sintered disk (40–90 micron range).
• 47 mm aluminum clamp.

Vacuum Filtration of Aqueous Samples

Assemble the funnel, 47 mm sintered base, and flask with the aluminum clamp, apply vacuum, and filter aqueous samples through the G2 (40–90 micron) disk. Official copy lists a 9.6 cm² effective area and a design meant to maximize flow and reduce foaming.

Classroom Care

Support the flask, inspect the sintered disk and glass before each use, and disassemble and rinse all four pieces after filtration.
