Supplier: Merck

Hydrophobic edge membranes are standard MF-type filters with edges rendered hydrophobic to 3 or 6 mm widths. In antibiotic and bacteriostatic drug sterility testing by membrane filter method, the 6 mm wide non-wetting edge prevents drug intrusion under holder sealing rim.

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: Sartorius

Cellulose nitrate hydrophilic membrane filters. For sample pretreatment, particle testing and chemotaxis.

Supplier: Whatman products (Cytiva)

A fast filter paper with high wet strength. It has a very smooth surface making it easy to scrape or wash off precipitate.

Supplier: Whatman products (Cytiva)

These are glass microfibre filters for general filtration applications.

Supplier: Merck

Filters for sterilising or clarifying biological solutions. The larger filtration area increases flow rate and throughput. It also makes it easier to filter solutions because it reduces the pressure required to empty the syringe.

Supplier: Whatman products (Cytiva)

A very thick filter with high wet strength. Offers medium to slow flow rate and retains very fine precipitates.

Supplier: Whatman products (Cytiva)

These cellulose filter papers are intermediate in speed and retention between grades 1 and 4.

Supplier: Cytiva (Formerly Pall Lab)

Acrodisc™ PSF high performance syringe filters can be used for general clarification or application specific uses like dissolution, HPLC, and IC. Engineered to work in most automated filter systems.

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

The Last Drop™ eluent filter utilises a flat element, which sits parallel to the bottom of the reservoir, allowing the filter to draw all but the last 2% of the eluent without drawing air into the system. The filter consists of a 316 stainless steel or PTFE filter element in an inert housing.

Supplier: Sartorius

These cellulose nitrate membranes are suitable for air monitoring.

Supplier: Whatman products (Cytiva)
