PBQK07610 Ultrafiltration Discs, 50 kDa NMW 202 
Add to Cart
  • Background Information
  • 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

SCGVU05RE Stericup-GV Sterile Vacuum Filtration System Special offer 
Add to Cart
  • Background Information
  • The Stericup® vacuum filtration system is the most efficient single-use, disposable process for sterile media preparation. It combines a Steritop® filter unit with a receiver flask for processing and storing volumes from 150 mL to 1,000 mL in a single, ready-to-use format. Its no-tip, easy-grip flask design and balanced profile improve stability during filtration in tight laminar flow hoods, and the convenient labeling and packaging make it easy to open and track each device. The bottom of the receiver flask is slightly recessed, so you can conveniently stack capped flasks after filtration, maximizing precious refrigeration space. You can also use Steritop® bottle-top devices with your own sterile capture flask or bottle. Features & Benefits Millipore Express® PLUS membrane for fastest flow rates and low protein binding to minimize absorption and protein loss, which affect downstream performance and costs Durapore® membrane for ultra-low protein binding for minimum absorption and protein loss Snug tight packaging, easy tear-open pouch, and convenient label designs make storing, opening and tracking your devices easy and efficient Stable base and easy grip design of the Stericup® device enable any user to comfortably perform all stages of the workflow in a laminar flow hood Recessed bottom of Stericup receiver flasks allows flasks to be stacked easily in refrigerated spaces Applications Sterilization of Aqueous Solutions (150 mL to 1 L); Sterile Filtration of Culture Media and Buffers with High-Value Protein or Small Molecule Component
