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.

  • 95 - 98% Sample Recovery
  • Highest Membrane Purity
  • Superior Handling & Leak Prevention
  • Volume Specific Dilution Control
  • Complete & Ready-to-Use
  • Perfect for dialyzing electro-eluted proteins or chromatography fractions

Sample Recovery, Purity and Dilution Control
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.

Designed for Ease-of-Use and Leak Prevention
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.
