Filtration apparatus

UniFilter^® 800, well capacity: 800µl. Drip director type long.

• Complies with ISO 6556
• Büchner type flasks for vacuum filtration
• Heavy walls provide increased mechanical strength
• "Studded" base to minimise surface abrasion
• With integral glass side-arm to accept 9mm bore flexible tubing

Type 163. For particle testing or radiochemical work. For ultrafiltration and sterile filtration. Autoclavable. PTFE-coated, steel screen filter support.

For sterile ventilation of fermenters, culture vessels, etc. or to act as a water barrier between the suction flask and the vacuum pump in filtration applications. The supported PTFE membrane within a PP housing gives excellent chemical resistance. Filter in either direction (3 bar max. pressure).

• Stepped horse-barb of 6-12 mm on either sides
• sterile single packed filters, autoclavable

The MBS I filtration system is designed for laboratories that handle high numbers of samples for microbiological quality control. It consists of a membrane dispenser, a funnel dispenser, and a 2-place filter AS220 manifold.
AS220 Filtration Manifold and Filtration funnels AS220 is a two-place stainless-steel filtration manifold, which can be joined together (maximum of 3 manifolds).This simple manifold can be used with 47mm or 50mm filtration membranes.

• Waste reduction - because PP funnels can be autoclaved up to 50 times
• Time saving - No need to flame in between filtrations
• Easy handing
• Cost saving - 20 PP funnels are enough for 1000 analyses
• Reduces cross-contamination

The Whatman Mini-UniPrep™ filter provides a quick and easy means of removing particles from HPLC samples. In comparison to other methods the amount of time required for sample preparation is reduced to one third. Mini-Uni-Prep™ is a ready-to-use filter unit consisting of a 0.4ml chamber and a plunger. The plunger contains a filtration membrane at one end and a cap with septum at the other. The plunger is pressed through the sample in the chamber. The pressure generated forces the filtrate into the plunger reservoir, with air escaping through the vent hole until the locking mechanism engages to form an airtight seal. The unit can now be placed in any autosampler and the sample analysed.

For 47mm diameter membrane filters. With reservoir barrel allowing up to 200ml of liquid to be filtered by connection to a suitable direct pressure source. Can also be used for filtering larger volumes in conjunction with a 5L pressurising container. Complete with silicone O-rings and 10mm diameter tubing ferrules on the inlet and outlets. For sterile filtration of tissue cultures, ultrafiltration of buffer solutions, cell count solutions and for pressing soil samples.

For 142 mm diameter membrane filters. With large capacity barrel allowing up to 2 litres of liquid to be filtered by connection to a suitable direct pressure source. For preparing sludge or separating suspended matter from waste water samples, or sterile filtration of liquids that are difficult to filter, e.g. serum. Filtration surface area: 130 cm². Maximum pressure 7 bar. The holder is supplied complete with a back pressure screen.
