Syringe filters

CHROMAFIL^® syringe filters are used for filtration of suspended matter from liquid samples. HPLC-Certification available on the internet
Polypropylene housing
Better solvent stability compared to acrylate and polystyrene filters
Shells ultrasonically sealed, not glued
No extractable components from glues
Filtration in both directions possible, the liquid cannot bypass the membranes
Luer lock on side of entry
Safe connection on the "high pressure" side
Luer exit
Standard luer for 3mm and 25mm filters, minispike luer with low dead volume and small OD for 15mm filters
Deflector
The stream of liquid is broken and distributed, and does not directly hit the membrane: this prevents rupture of the membrane
Star-shaped distribution device
The liquid is evenly distributed to the whole membrane surface: this results in a better utilisation of the total area; the filter is not rapidly clogged up; high flow efficiency
Colour coded
Filters with 0.2µm pores have a yellow upper housing, for filters with 0.45µm pores this is colourless; the different membrane types are distinguished by different colours
Low dead volume
~80µl for 25mm, 35µl for 15mm, 5µl for 3mm.

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.

Chromafil™Xtra:
Labelled for method validation and certification. Colour-free plain polypropylene housing. Imprint for direct identification of the membrane type, diameter and pore size.
Hydrophilic membrane for polar as well as non-polar solvents. The HPLC filter, especially suited for mixtures of water and organic solvents; for TOC/DOC determination; not cytotoxic, does not inhibit the growth of microorganisms and higher cells. Polyester filter with integrated glass fibre prefilter (GF/PET): recommended for solutions with a high load of particulate matter or for highly viscous solutions.

Inert Filter, nominal pore size 1µm, allows higher flow rates than smaller pore filters. For solutions with high loads of particulate matter or for highly viscous solutions (e. g. soil samples, fermentation broths) as prefilters for other CHROMAFIL^® filters, they prevent plugging of the membrane.

For the ready-to-use filter units only virgin raw material is used. This ensures that there is no interaction with the sample to be filtered, provided that the units are used properly. The filter units are intended for laboratory use only and at temperatures up to 60°C.
Note: If syringes with a volume <10 ml are used, a pressure could be created which exceeds the max. operating pressure (700 kPa/7 bar) of the filter unit. EtO-sterilized = endotoxin free according to LAL-Test (USPXXIII), Sensitivity: 0.25EU/ml.

• Inlet female luer-lock
• Outlet luer cone or extended tip
• Autoclavable at 121°C

Suitable for HPLC sample filtration (water-based) and aggressive water solutions such as acids and alkalis.

A hydrophobic membrane. Ideal for filtration of non-polar liquids and gases. It is very resistant to various solvents as well as acids and bases. By flushing with alcohol, followed by water, the original hydrophobic membrane can be made more hydrophilic.

Used for large volumes of aqueous samples. Presterilized. Contains a nylon membrane which is inherently hydrophilic, has low extractables, is bio-safe and has excellent flow rates. A glass microfibre prefilter ensures a long working life for the main filter and allows the easy filtration of large volumes and difficult samples.
