MilliporeSigma Filters

Both syringe filters as well as membrane filters of MilliporeSigma are characterized by upmarket manufacturing and high reproducibility of results. Syringe filters are available in our shop in the following materials: MCE, PA, PES, PTFE, PTFE/GC and PVDF. Materials like MCE, PA, PC, PES, PTFE and PVDF are used for Merck Millipore membrane filters.

Millex filters

The quality Millex filter by MilliporeSigma are suitable for sterile filtration, filtration at high particle load, as ventilation or gas filter, the general filtration and chromatography.

Under the Millex filter series MilliporeSigma produced sterile filter with a pore size of 0.22 microns or smaller for applications in the field of sterile filtration. These come in use in biological solutions, tissue culture media and media additives or buffers. The users can choose between the Millipore Express (PES), which is distinguished by high flow rate and low protein binding, the Durapore (PVDF) with extremely low protein binding and the mixed cellulose ester (MCE) for general applications which binds protein contaminants simultaneously. The range of Millex filter is the Millipore LCR (hydrophilic PTFE) with its broad chemical compatibility. The filters are produced as standard with 25 mm or 33 mm (new) which brings greater throughput and a higher flow rate with it.

For a filtration at high particle load the HPF Millex filter, a graduated prefilter and a membrane filter for the filtration of solutions with high particulate loading with large throughput is. Those filters find application in the wine analysis, general particle removal and sample preparation for chromatography. The membrane filter are made of either nylon, which has a broad chemical compatibility or Durapore (PVDF) - this is the membrane with the smallest protein binding on the market. The housing of the filter is made of HDPE, which is compatible with the most commonly used solvents. Not only with their procurement the graduated fiberglass prefilter and membrane filter can score: the high-quality filter managed to resolve a multivitamin tablet overnight and filter it at 0.3 bar - quick results do not take long with these filters.

In chromatography, the filtration is carried out as a regularly application. For this purpose, users require non-sterile filter with a small proportion of extractables for the removal of small particles having a pore size of 0.2 or 0.22 micron; also for clarification before the instrumental analysis these conditions are indispensable. Millipore provides for general particulate removal, HPLC, IC and GC a series of high-class membrane filters: Durapore (PVDF) for easy organic solutions at extremely low protein binding, membrane filter made of nylon for aqueous and organic solutions, Millipore LCR (hydrophilic PTFE) for aqueous and weak organic solutions and Fluoropore (hydrophobic PTFE) of organic solvents.
