Whatman Grade 1 Qualitative Filter Papers are the most widely used filter paper for routine laboratory applications, qualitative analytical separations, and clarifying liquids. They are the standard grade cellulose filter papers for medium flow rates.

Supplier: Cytiva

Whatman Grade 4 Qualitative Filter Papers are a standard grade, high flow rate filter paper. They are useful in qualitative analytical separations when fast flow is required and the collection of fine particles is not critical.

Supplier: Cytiva

Puradisc™ syringe filters combine premium quality and economy. They are ideal for the quick, efficient filtration of samples up to 100 mL volume. Puradisc filters are produced from pigment-free polypropylene or polycarbonate with standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated). Options include a sterile, medical-grade blister pack for critical applications and a special tube tip outlet that allows the sample to be accurately dispensed into a micro-vial, eliminating air lock.

Tris (tris[hydroxymethyl] aminoethane) is suitable for preparing electrophoresis buffer in the pH range of 7,2 to 9,0. It is qualified for 2-D electrophoresis.

Supplier: Cytiva

Acrodisc™ syringe filters with Supor™ membrane deliver high flow rates and low protein binding.

Supplier: Cytiva

Ideal for the isolation and enumeration of yeast and mold colonies from water and beverages using the Membrane Filter Technique referenced in Standard Methods for the Examination of Water and Wastewater. Dark background provides an excellent contrast for counting opaque colonies and light colored particulate.

High Quality Filter Paper.

Supplier: Cytiva

Balanced salt solution used for multiple cell culture applications, (liquid form).

Supplier: Cytiva

For use in cell culture and other sensitive biological research.

These 25mm filters are ideal for scale up. Filters feature a polypropylene housing and a choice of four membrane types to assure compatibility with a wide range of fluids. Choose Supor® (hydrophilic polyethersulfone), Ultipor® (amphoteric Nylon N66), Fluorodyne® II (hydrophilic polyvinylidene fluoride), or Posidyne® (positively-charged Nylon N66) membrane. Filters are tested for bacterial retention to assure sterile filtrate and can be integrity tested by the water bubble point method. There is no need to change membrane materials during transition to pilot or full-scale production. Filters have a female Luer-lock inlet and a male slip Luer outlet. Sterilized by gamma irradiation.

Supplier: Cytiva

Ideal for gravimetric analysis of air pollutants and as prefilters for use upstream of membrane filters.

Supplier: Cytiva

For vacuum filtration of liquids, especially for the analysis of aqueous samples for microbiological and particulate contamination using the Membrane Filter (MF) Technique.

Supplier: Cytiva

These premium syringe filters combine the benefits of a multi-layered prefiltration device with an automation-certified filter housing. The polypropylene housing has been designed to withstand high operating pressures. Some models feature a GxF borosilicate glass prefilter, which provides two to four times the throughput of standard glass fiber prefilter devices, allowing for quick and easy filtration of difficult-to-filter samples.

Supplier: Cytiva

Easy to use, versatile, disposable filter funnels are ideal for microbial analysis. Polypropylene construction eliminates compatibility or extractables issues. Ergonomically designed units allow for removal of funnel cylinder with a squeeze. The base and cover convert to a petri dish for culturing the membrane in place, or the membrane can be cultured on a separate petri dish. Unit fits directly onto a standard manifold, or a stopper/adapter combination can be used for other manifold styles. Gamma irradiated. Bulk packed. Volume: 100mL.

Supplier: Cytiva

This disposable protective device is designed to prevent aqueous liquid and aerosol contamination of vacuum pumps or aspiration suction systems.

Supplier: Cytiva

For filtration of aqueous and some organic-based samples. Two prefilters [gradient density multigrade GMF 150 (10:1µm) and Grade GF/F (0.7µm)] allow filtration of even the most difficult samples with minimal hand force. Choose the 13mm size for samples up to 10mL or the 25mm size for samples greater than 10mL.
