Supplier: Cytiva (Formerly Pall Lab)

Nylon 6,6 membranes for fluid filtration in the pharmaceutical, biotechnology, electronics, food and beverage industries and for analytical applications. These membranes are very resistant to mechanical, chemical and thermal stress. They can be used in either direction, are inherently hydrophilic, have high flow rates, low pressure drops and very low extractables. Where appropriate, they can be steam sterilised without change in flow or pore size characteristic.

Supplier: Cytiva (Formerly Pall Lab)

Hydrophilic acrylic polymer Versapor® membrane on non woven support ideal for pre-filtration of difficult to filter solutions and serum.

Supplier: Cytiva (Formerly Pall Lab)

Low extractable, binder-free borosilicate glass fibre filters. Suitable for use of the EPA 1311 Toxicity Characteristics Leaching Procedure and for prefiltration of dirty HPLC samples.

Supplier: Spectrum Laboratories

These woven filters are constructed of individual strands woven into a mesh screen, characterised by precise mesh openings, percent open area and mesh thickness. Available in five material types with different physical, chemical and thermal characteristics to select from depending on your application. Available in discs or square sheets.

Supplier: Whatman products (Cytiva)

Smooth filter papers with good retentivity at a relatively high filtration speed. They are used for the clarifying filtration of dried beet pulp extracts or beet juice after the addition of lead acetate for subsequent polarimetric sugar determination.

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.
