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
Flow restrictor set
Set consisting of a blue and green flow restrictor. The blue flow restrictor can increase the filtration rate, while the green flow restrictor can be useful when handling high-viscosity feeds or to reduce shear stress on aggregation-prone molecules.
Micro dialysers QuikPrep® Micro DispoDialyzer
Disposable dialyser for processing sample volumes from 5 to 100 µl. The entire unit floats directly in the dialysis buffer. To reduce the dialysis time, the dialyser can be placed in a beaker on a magnetic stirrer. After dialysis, the dialyser is placed in a new microcentrifuge collection tube and briefly centrifuged (500 to 2000 rpm for 1 to 2 seconds). Ideal for buffer exchange, detergent removal, sample preparation for HPLC/HPCE/GC/GC-MS/NMR, as well as purification of proteins, DNA and RNA.Easy handlingLeak-proofLow protein bindingHigh sample recoveryRapid dialysis/purificationThe micro dialyser comes with a foam float, cap, and two 1.5 ml collection tubes.
Peristaltic pump for TFF cassettes
Peristaltic pump for pumping liquids and processing samples with Vivaflow® tangential flow filtration cassettes (TFF) and Sartobind® chromatography consumables. These pumps are designed for ultrafiltration, diafiltration, and purification. The digital control ensures a constant flow. A reversible variable speed motor allows precise flow control in both directions. Tube loading into the separately available pump heads is quick and easy.Please order pump heads and TFF cassettes separately.
Pre-treated RC Dialysis Tubing Spectra/Por® 7
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 treated to remove trace levels of heavy metals and sulphide compounds. Ready-to-use Dialysis Tubing already equilibrated in water and supplied in 0.05 % sodium azide solution. Simply rinse away the preservative solution with DI water, load the sample and dialyze.
Pre-wetted RC Dialysis Tubing Spectra/Por® 6
