Dry RC Dialysis Tubing Spectra/Por® 1, 2, 3 and 4

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 °CRC 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.Spectra/Por® 1, 3 und 4:For standard dialysis, different MWCO and flat widthsSpectra/Por® 2:Dialysis Tubing with higher permeability

Dialysis tubing closures Spectra/Por, PP

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.Clips for Biotech membranes available on request.

Dialysis Tubing Biotech Cellulose Ester (CE)

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.
