Glass Vacuum Filtration Holder for 47/50 mm Membrane Filter, 1 L Bottle

All-Glass Vacuum Filter Holder 1 l | 50 / 47 mm diameter Vacuum only | 47 / 50 mm Volume: 1 l Membrane: 50 / 47 mm diameter Max. operating pressure: Vacuum only Diameter: 47 / 50 mm Number of Filter Holders or Stations: 1 All-glass Holder for particle removal from solvents for analytical determinations. All areas, where liquid and device can get directly in contact, are made of glass or PTFE. The device, in combination with solvent-resistant, hydrophilic RC-membranes (type 184), is therefore ideal for ultracleaning and degassing solvents and solvent mixtures for HPLC, GC and AA. Convinience of handling is ensured by several beneficial features. A 6 mm wide non-ground rim above the ground glass neck of the suction flask prevents the filtrate from contacting grease on the ground glass surface and so avoids it becoming contaminated while being poured out of flask. The hose nipple connector is made of polypropylene for safe connection of vacuum hose. The filtrate outlet spout ends well below the entrance to this hose nipple.
