Syringe filters

LABSOLUTE® offers a comprehensive range of syringe filters that have been developed especially for the efficient filtration of aqueous and organic solutions and for ventilation. The choice of different housing diameters, membrane types and pore sizes offers the ideal solution for your applications. Intensive quality checks ensure consistently high quality, both of the membrane material and the filter unit as a whole, for all of the filters we supply.

• Made without the use of adhesives: the housing and membrane are welded
• Sterile versions: 100 % sterility thanks to gamma radiation
• Equipped with Luer connections
• The filters are printed, both with the membrane type and the pore size, excluding the possibility of confusion

SETUP

The syringe filters have either acrylic or PP housing. Both housing versions have Luer connections, and the membrane is secured in the housing so that the sample fluid cannot flow around the membrane.

LABSOLUTE® syringe filters with a filter membrane diameter of 25 mm are ideal for the preparation of samples with a volume from 1.5 ml to 100 ml. The effective filtration area is 4.6 cm². This, in combination with the stable housing pressure resistant to 5 bar made from polypropylene (transparent) or acrylic (pore size 0.22 µm blue or pore size 0.45 µm yellow), ensures rapid filtration. The non-sterile filters are packed in quantities of 500 in polypropylene pouches, while sterile filters are packaged individually in blisters in quantities of 50 per box.

Properties:

• Housing diameter 33 mm
• Membrane diameter 25 mm (surface 4.6 cm²)
• Low content of extractable substances
• Low dead volume

The LABSOLUTE® ProFill Syringe filters are suitable best for sample volumes of 1.5 up to 100 ml. The ultrasonically welded polypropylene (PP) housing of the syringe filters ensures high pressure resistance. The membrane is fixed in the housing in such a way that a by-passing of the sample liquid is impossible. The colour-coding enables easy identification of the filter’s membrane type. Furthermore membrane type and pore size are printed onto the PE bag, in which the filters are tamper-proof evidently packed with 100 pieces each. An additional blue reclosable PP box offers further protection for the filters during transportation. Due to their Luer Lock-Inlet (female) an easy and safe installation of the filter on the syringe is guaranteed. The outlet is designed as Luer Slip (male). Thorough quality controls before and after the manufacturing process guarantee a constantly high quality of the membrane material as well as of the complete filter unit.

Specifications
The membrane housing consists of polypropylene (PP). This material is very resistant towards most solvents and has a very low extractable substances content. Thus it can be used with almost all solvents, acids and bases (see table). The especially thick rim of the housing is ideal for use with laboratory robots (e.g. Benchmate™). Filter inlet and filter outlet can be fitted to the CHROMABOND^® columns for selective sample preparation with the aid of a special adaptor. All filters can be autoclaved at 121°C and 1.1bar for 30min.

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.
