Microfilter plates

Biologically inert and ultra-pure, Biotech CE is available in the largest selection of concise MWCOs (0.1 to 1000 kD) and sizes to provide better molecular separation for desalting, isolating ionic species and macromolecular purifications. Moderate chemical compatibility tolerates weak or dilute acids or bases and mild alcohols with only a slight change to the MWCO. Not for use with organic solvents. Use with pH 2 to 9 and temperature 4 to 37 °C.

Ready-to-use dialysis device with screw cap for ultimate convenience for small volume dialysis. Easy loading and recovery. No needles, closures, knots, buoys, pontoons, or weights required. Made with Biotech CE membrane in 9 MWCO"s (0.1 to 1000 kD) and 3 volume sizes (1, 5 and 10 ml).

Standard and Weighted Spectra/Por Closures provide a leak-proof seal for dialysis tubing while aiding in sample buoyancy and vertical orientation. They are available in 23, 35, 55, 75 and 90 mm sealing widths and a variety of colors for easy sample identification. Closures are autoclavable.

Standard Grade Regenerated Cellulose (RC) is a clear, flexible and sturdy dialysis tubing. This tubing is ideal for a broad range of applications in which there is a significant size difference between the MW species being separated, including sample preparartion, desalting, buffer exchange, pH change, protein purification. Offering a good chemical compatibility, Standard Grade RC can be used with dilute strong acids and bases, concentrated weak acids and bases, most alcohols and some mild or dilute organics, including DMSO. Standard RC can tolerate pH 2 to 12 and temperatures 4 to 121 °C
RC dialysis tubing supplied dry with glycerol humectant for easy handling and manipulation. Soak in DI water for 30 minutes to remove glycerol. Contains trace levels of heavy metals and sulphides.
