Recommended for microbiological culturing and sample preparation, these cellulose nitrate membrane filters offer very narrow pore size distribution and low levels of extractables.

Supplier: Sartorius

PES membrane filters are hydrophilic, have high flow rates thanks to the symmetric structure, have a low non-specific protein adsorption and are chemically resistant over a pH range of 1 to 14. They are recommended for the filtration of aqueous solutions as well for the protein filtration. Furthermore, the low level of extractables makes them suitable for environmental analysis.

Supplier: ENTEGRIS

These point-of-use filters meet small to mid-volume photochemical filtration needs for positive developer and DI water applications. Both Optimizer® DEV filters (for developer applications) and Optimizer® DI filters (for DI water applications) require no pre-wetting, so the filters function immediately after installation. The design also limits the handling of hazardous chemicals during the installation and promotes a healthier workplace. Do not use either filter with aromatic hydrocarbons.

Supplier: Whatman products (Cytiva)

These syringe filter holders are made from stainless steel. The holders with Luer lock fittings connected to a standard syringe offer quick and easy clarification, sterilisation and removal of particulates from small volume samples, typically for HPLC applications.

Supplier: Whatman products (Cytiva)

Cytiva's Whatman cellulose acetate membrane filters have very low protein binding, which minimizes sample loss when filtering protein-based aqueous samples.

Supplier: Whatman products (Cytiva)

High quality nylon membranes are suitable for filtering aqueous solutions and most organic solvents. They are suitable for use with a wide range of biological preparations and can be used where other membranes are unsuitable or difficult to use.

Supplier: ENTEGRIS

These filters provide superior filtration for critical dilute, aqueous and low neutral pH cleaning applications at advanced technology nodes. The clean, dual capture membrane improves process performance and reduces on-wafer defects. In addition to sieving particle capture which is always active, the non sieving retention mechanisms are also active and strongest in conditions where pH is <3 and no surfactant is present.

Supplier: Corning

FiltrEX™ filter plates meet the industry standards for plate dimensions. The rigid side walls make the plate ideal for automation and the wide skirt accepts barcodes. Individual filter discs are encapsulated in the plate by a process that ensures 100% integrity of each well. The design of the nozzle prevents sample wicking and cross-contamination. Glass fibre filter plates can be used for a variety of applications, such as plasmid isolation, DNA purification, PCR clean-up or receptor/ligand binding assays. The low-binding hydrophilic PVDF membrane can be used for lysate clarification, protein kinase assays, or bead- or resin-based separation assays.

Supplier: Sartorius

Each set consists of a Ø 50 mm or Ø 47 mm pad, impregnated with nutrient media, packed dry and sterile in a Petri dish, with a membrane filter. After filtration of the sample the membrane is placed in the dish and incubated. More types available on request.

Supplier: UPCHURCH SCIENTIFIC

These filters are designed to seal and filter simultaneously by incorporating a frit into the body of a flat-bottom ferrule.

Supplier: Whatman products (Cytiva)

Cytiva's sterile Whatman MicroPlus-21 cellulose nitrate membrane filters are for microbiological quality control. The STL version is compatible with Membrane-Butler and other membrane filter dispensers.

Supplier: Whatman products (Cytiva)

Nuclepore™ track-etched hydrophilic membrane filters offer a highly defined pore size cut-off in the submicron range, enabling particle deformity measurement and capture of extremely small particles. The membranes have sharply defined pores, high flow rates, and excellent chemical and thermal resistance. They are suitable for a variety of samples and applications, including microscopy, cytology, parasitology, and certain air and oceanography analyses.

Supplier: Avantor

Avantor® ACE® UHPLC pre-column filters made from stainless steel/PEEK provide protection for all UHPLC columns. They offer ultra-low dispersion for maximum compatibility with UHPLC instruments and columns.

Supplier: ENTEGRIS

The point-of-use photochemical filters with superior contaminant retention and low hold-up volume performance in sub-10 to 180 nm technology nodes. Both Optimizer® D300 and D600 filters are geared to small-volume filtration of photoresists, resist dielectrics, and solvents. It requires no pre-wetting, so the filters function immediately after installation. Without the need for prewetting, they reduce the likelihood that microbubbles will form and avoid the problems associated with incomplete wetting and the mixing of incompatible chemicals.
