MWCO 6 to 8 kD, regenerated cellulose.

Supplier: SPECTRUM CHROMATOGRAPHY

Ready-to-use laboratory dialysis systems featuring proprietary Ultra-pure Biotech Cellulose Ester (CE) Membrane. Biotech Grade CE is a low protein-binding synthetic membrane available in 9 precise MWCO's with no heavy metal and sulfide contaminants. The cylindrical tubing geometry prevents sample dilution (associated with cassette-type devices) and provides open access for total volume retrieval by pipette. Only the Float-A-Lyzer® G2 assures a 95 to 98% sample recovery while maintaining 99% sample purity and <1% sample dilution. The leakproof screw-on cap with sealing o-ring provides easy access with included pipette for loading, in-process testing and sample retrieval, without the risk of needle punctures. The included floatation ring improves sample buoyancy and vertical orientation during dialysis. The sleek design allows multiple samples to be dialysed in the same reservoir.

Hollow fibre filter modules are particularly useful in tangential flow filtration because processes can easily be scaled-up from small volume applications to full-scale production.

These woven filters are constructed of individual strands woven into a mesh screen, characterised by precise mesh openings, percent open area and mesh thickness. Available in five material types with different physical, chemical and thermal characteristics to select from depending on your application. Available in discs or square sheets.

Biotech RC (Regenerated Cellulose) dialysis tubing is crafted from a regeneration process that yields superior temperature tolerances and chemical compatibilities with the same high purity and selectivity as Biotech CE. RC membrane can tolerate concentrated-weak acids & bases, dilute-strong acids and bases, most alcohols and some mild or dilute organic solvents. Exposure to strong polar or organic solvents may damage RC membranes. Use with pH 2 - 12 and temperature 4 - 60 °C.

Spectrum's KrosFlo Research I (KRI) system combines a digital peristaltic pump and a multi-purpose lab stand to provide ultimate convenience and efficiency for experiments involving fluid circulation and transfers. The easy-to-operate digital KRI pump drives the fluid stream through flexible tubing (to be order separately) while the incorporated stand and included holders secure the tubing, filters, reservoirs and other components in place.
