Filtration and vacuum

Acid transfer pumps

Self priming pump constructed in polypropylene, with internal parts of high density polyethylene for application with a wide variety of chemicals. lt fits any 15, 30 or 55 gallon drums with either 3/4" or 2" openings.

Hand operated vacuum pump

Light, portable hand operated vacuum pump, attains a vacuum of 625 mm Hg (25"). Pumping rate is 15 ml per stroke. Built in vacuum release valve. Can be used as pressure pump by transferring release valve cap to vacuum port. Nozzle fits standard 6 mm (1/4") i.d. tubing.

Dispensing pump for solvent transfer with heavy nickel chrome plated body. Model M45 (Art. n. 2005) fits bottles of buckets with any size and type of openings. Model M855 fits 2" openings in any size drum. NOTE: Solvent pumps are NOT suitable for use with ACID.

Filter Pump

This pump willwork on pressure up to 10 Kg/cm². Built in non return valve to eliminate back flow. Useful for sucking to waste any split chemicals as well as for filter work. Easily dismantled for cleaning. Autoclavable.

Prevents water back flow when pressure falls. Useful for any tubing system and vacuum line. Maximum safe working pressure: 2 BAR (equal approx. 28.4 P.S.l.) minimum safe working pressure 0,07 BAR at room temperature (20°C).

Longstem funnels

The 60° angled sides are provided with ribs for fast filtration and allow the use of standard sizes filter papers.
 

Robust, lightweight. Unbreakable and resistant to corrosion and heat (max 120°C). Two piece construction. Top and bottom can be separated for easy and total cleaning. Autoclavable. Excellent chemical resistance.

Discs for Buchner funnel

Useful interface between filter paper and perforated Buchner plate. Avoids clogging of filtrate holes.
 

Designed specifically for analytical chemistry. Each size takes a standard size filter paper. Body of funnel is exact 60° angle. Provided with external and internal ribs. Can withstand temperatures up to 120°C and may be autoclaved.

Desiccator plates 

These plates made of semiexpanded polypropylene are extremely useful as a support for crucibles, Petri dishes etc. Use at room temperature. Not suitable for use with hot crucible.
