Screw filter 250 ml, with funnel, head,

Screw filter 250 ml is a modular laboratory glass filtration assembly for vacuum or gravity filtration of liquids in chemical, pharmaceutical and life-science laboratories. It is supplied with funnel, attachment and seals but without a filter plate, so the user can freely select the frit porosity required for each application. The filter plate diameter is 50 mm and the screw thread measures 54 mm, giving a secure connection compatible with standard laboratory glassware. This screw filter from manufacturer Witeg has a net weight of 0,13 kg and is intended for interchangeable glass filter plates used in sample preparation, precipitate collection, recrystallisation work-up and solvent clarification. The 250 ml working capacity suits medium-scale filtrations, while the robust glass construction supports repeated cleaning under typical laboratory conditions. Offered as a single piece, the unit belongs to the product groups covering glass filters, frits and glass nutsche filters and originates from Germany.
