Filtration Membranes and Paper Products & Reviews

Pkg of 60, 11.3 x 7.7 cm, precut absorbent filter paper for blotting applications requiring thick, high-wet-strength filter paper

Hydrosart® high performance membrane is a stabilized cellulose based membrane optimized for biopharmaceutical process applications. It is stable across a broad pH range and extremely hydrophilic, making it non-protein binding and virtually non-fouling.

Sartopore® 2 is the industry standard of high-performance polyethersulfone (PES) liquid filters

The Sartocheck® 5 Filter Tester is an automatic filter integrity tester designed to cover the complete range of integrity testing from small syringe filters up to large multiround housings and tangential flow cassettes.

10mm Filter Supports (100/pk)

Cytiva's Whatman Benchkote surface protector is an absorbent lab paper that protects surfaces against hazardous spills. After use, the bench protector sheet is incinerated or disposed of according to local regulations. 

Whatman 1PS Phase Separator from Cytiva's business is a hydrophobic filter for routine solvent extraction. Within seconds it retains aqueous phases, while solvent phases flow through.

Cone folded filter paper saves valuable time when undertaking repetitive or multiple analyses.

Pyramid (square) folded filter paper is easy to use and saves valuable time when undertaking repetitive or multiple analyses.

Whatman cellulose filter paper grades are now available in a flat, quadrant folded format to fit conical filter funnels.

Grained, with medium fast flow rate and medium retention. A universal filter paper, used for the filtration of extracts, oils, beer, syrups etc.; also applied in filter presses or for the aspiration of liquids.  

Cytiva's Whatman parchment weigh boats are designed so users can collect, transfer, and drop both sample and weighing boat into the acid solution during a Kjeldahl analysis without influencing analytical results.

Grade B-2 Whatman weighing paper from Cytiva dissolves residue-free in acid solution, which is critical in applications such as Kjeldahl analysis of nitrogen in soil.

Cytiva's Grade 2122 weigh paper sheets reliably allow samples to be transferred to scales without adding unwanted substances that could impact analytical results.

Whatman Solvent IFD from Cytiva is a high-flow in-line filter/degasser (IFD) of chemically resistent polypropylene housing and membrane. It connects to an HPLC line to simultaneously filter and degasses during mobile phase preparation.

Cytiva's Whatman PM2.5 PTFE membrane filters are designed for PM2.5 air monitoring. These high-purity, thin filtration devices are sequentially numbered and housed in chemically resistant polypropylene support rings for robotic air sampling.

Cytiva's Roby filter validation kit offers five different Roby automated syringe filters, along with a filter validation protocol and filter selection aid. Tubes of 25 filters are ready for loading into tablet tester systems.

Non-sterile syringe filter used for hard-to-filter material with high solids as in environmental and food analysis samples.

A next generation microporous membrane for a full range of consumer electronic applications. Solupor® membrane has a unique combination of high porosity of >80% and low thickness, which makes it possible to achieve very low electrical resistance in capacitor applications. With its superior mechanical properties, microporous structure, and smooth surface, Solupor membrane is an ideal substrate for the construction of proton…

Delivers uniform wet out and added strength during use in critical filtration applications. Nylopor™ membrane is a naturally hydrophilic membrane, engineered with a polyethylene support based on Lydall’s microporous Solupor® membrane. Nylopor membrane’s hydrophilic characteristics provide uniform wet out and added strength during use in critical filtration applications. The membrane is comprised of nylon 4, 6 to provide incre…

Provides an ultra-hydrophilic platform for critical process filtration. Evopor™ membrane is a naturally hydrophilic, supported membrane manufactured to provide uniform wet out and maintain its strength during use in critical filtration applications. Unlike polyethersulfone (PES) and polyvinylidene fluoride (PVDF) membranes, Evopor membranes are comprised of Ethyl Vinyl Alcohol (EVOH) to provide an unparalleled ultra-hydrophil…
