We have developed a unique portfolio of consumables, each adapted to the different feed water quality requirements and to your various applications. To maintain your water system’s performance, it’s critical to replace your purification cartridges on time and with genuine ISO 9001-certified parts.
Centriprep® centrifugal filters are disposable ultrafiltration devices used for purifying, concentrating, and desalting biological samples in the 2–15 mL volume range. These complete, ready-to-use ultrafiltration devices are designed for operation in most centrifuges that can accommodate 50 mL centrifuge tubes. They are easy to use and offer a high flow rate. Centriprep® devices consist of a sample container with a twist-lock cap, a filtrate collector containing a low-adsorptive, Ultracel® regenerated cellulose membrane and an air-seal cap for sample isolation.Features & Benefits:•For use with samples containing high levels of solutes •Unique inverse flow mode of operation with large deadstop •Fast sample processing •Available with Ultracel® membranes: (3, 10, 30 and 50 kDa NMWL) •Fits standard swinging-bucket rotor for 50 mL tubes Applications:Concentration and Purification of Particle-laden Solutions, Solutions with High Solute Concentration, Separation of Low MW Solutes from Fermentation Broths, Cell Culture Media and Lysates

Biologically inert mixtures of cellulose acetate and cellulose nitrate have made MF-Millipore™ membrane filters one of the most widely used membranes in analytical and research applications. MF-Millipore™ filters without Triton® surfactant contain minimum amounts of wetting agent and have a lower water extractable content than standard MF-Millipore™ filters.Features & Benefits: - Versatile filter for biological and environmental monitoring applications - Available in a range of pore sizes, colored black or white, with or without a gridded surface - Compatible with ethylene oxide, gamma irradiation, and autoclave sterilization methods

Assemble your Amicon Stirred Cell with the membrane of your choice. Ultrafiltration cut disc membranes are available in Ultracel® regenerated cellulose and Biomax® polyethersulvone (PES). The membranes are available in a range of different pore sizes & diameters.Ultracel regenerated cellulose membranes are recommended for concentrating or desalting dilute solutions. The hydrophilic, tight microstructure of Ultracel membranes assures the highest possible retention with the lowest possible adsorption of protein, DNA or other macromolecules.Biomax PES membranes are recommended for concentrating or desalting higher volumes of more concentrated samples such as serum, plasma, or conditioned tissue culture media.Microfiltration Durapore® PVDF cut discs are available 0.1 µm, 0.22 µm, and 0.45 µm pore sizes in both 63.5 mm and 75 mm diameters.Features & Benefits:•Disc diameters include: 25, 44.5, 47, 63.5, 76, 90 and 150 mm •Both Ultracel®, Durapore®, and Biomax® membranes are available in a wide range of pore sizes to meet your separation requirements •Compatible with Amicon® Stirred Cells Applications:Concentration, Buffer Exchange, Desalting
