Features/Specifications: • Outlet spout 15 mm • Parts and materials Borosilicate glass funnel and base. Anodised aluminium clamp. Silicon caoutchouc lid. PTFE/glass filter support (type 16307) and PTFE/stainless steel filter support. • As for glass, PTFE and silicone. • With 0,2 µm membrane filter: 200 ml/min. • With 0,45 µm membrane filter: 600 ml/min. • With 0,8 µm membrane filter: 2.2 l/min. • Funnel capacity: 250 ml • Filtration area: 12.5 cm² • Max. operating pressure: Only for vacuum • Suitable membrane filter diameter: 50 mm (47 mm) • Sterilization: By autoclaving (121 °C or 134 °C) or by dry heat (max. 180 °C) • Stainless steel quality: High-grade stainless steel • Flow rate per filter station for water at 90% vacuum: 200 ml/min with 0.2 µm membrane filter, 600 ml/min with 0.45 µm membrane filter. • Outlet spouts (individual system): 10 mm outside diameter. • Outlet (for branches only): Hose nipple, DN 10. • 50 mm Glass Holder for particle testing or clarification and sterile filtration. • This filter holder is available in two versions differing from each other only in the type of the filter support. • The filter with glass frit ensures uniform distribution of retained particles and is therefore recommended, when the residue on the filter surface is of interest • The device with PTFE-coated screen support, on the other hand, is due to its ease of clean more preferable, when the filtrate is required or when liquids difficult to remove from glass frits have to be examined. • The PTFE ring which holds the glass frit and the screen support allows autoclaving the devices with a filter in position, and protects the edge of the glass frit from breakage and potential leakage. • It has a rim around the upper edge to simplify the positioning of the membrane filter when inserted and a silicone O-ring in the underside for leak-proof seal on the filtrate side.
