Filters

We offer a wide range of filters from different manufacturers. To provide you with a better overview, the filters are divided into membrane filters, glass fiber filters, filter papers and syringe attachment filters. Both the brand manufacturers offered by us such as MerckMillipore, Whatman and Sartorius as well as our own brand Altmann Analytik are manufactured exclusively from high-quality materials Thus we can ensure quality, reproducibility and uniformity for all filters. In addition, filter vials are an integral part of the product range. If you still can not find the right filter for your needs, we are happy to advise you.

Membrane Filter

Membrane filters allow the filtration of minute components by retaining impurities larger than the pore size on the membrane surface. This leads to a cleaning and concentration. The membrane filters differ in their pore size, material and diameter. They are mostly used for critical applications such as sterilization and end filtration. Paper filters are available as round filters or folding filters. Both differ in their diameters and thicknesses. There are also many other filter types like glass fiber filter, inline filter or gas GC filter.

In the following table the most common membrane filter materials and their retention characteristics are shown.

Celluloseacetate (CA)

Low protein-binding, well suited for sterile filtration and clarification of aqueous solutions, nutrient media, buffers, and sera, they provide superior chemical resistance to alcohol and oil. These hydrophilic membranes offer excellent flow rates as well as thermal stability up to 180°C max.

Cellulosenitrate (CN)

Cellulose nitrate membranes set the standard in both analytical and microbiological filtration. Cellulose nitrate is available in a range of pore sizes and is well suited for microbial analysis in water, food and beverage applications. Available in dispenser strips or individually sealed.

Polyamide (PA)

Membranes are hydrophilic and are widely used in both aqueous and organic solvent filtration applications. Well suited for sterilization and clarification of buffers and nutrient media with a low level of extractables.

Polycarbonate (PC)

PC membranes have uniform, smooth-bore, round pores that pass straight through the membrane creating a precise capillary structure. The smooth, flat surface of the PC membrane offers high visibility of captured particles.

Polytetrafluorethylen (PTFE)

Permanently hydrophobic filter material, very suitable for air and gas filtration. PTFE membranes are extremely resistant to aggressive solvents and acids and can be used to filter particulate from both liquid and gas samples.

Regenerated Cellulose (RC)

Regenerated cellulose membranes are resistant to solvents and are hydrophilic. 0.45 μm pore size is typically used for HPLC sample preparation.

 

Syringe Filter

The filter materials used for syringe filters are equivalent to the ones used in membrane filters. Please refer to the table of membrane filters above for that information.
