Spectrum introduces the Spectra/Por® Float-A-Lyzer® G2, the next generation in Ready-to-Use laboratory dialysis devices featuring proprietary Ultra-pure Biotech Cellulose Ester （CE） Membrane.
Spectrum's proprietary 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 95-98% sample recovery while maintaining 99% sample purity and <1% sample dilution.
The leak-proof 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 dialyzed in the same reservoir.
No additional kits, buoys or accessories are required. The Float-A-Lyzer G2 is packaged dry and ready-to-go with all components included.
