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.

Ultra-clean, PP columns with BAKERBOND® HPLC media are engineered to save time, minimise work and final solvent volumes and improve performance. Run times are up to nine times faster than conventional columns. The built-in column guard filter and higher analyte concentration may reduce or eliminate pre-filtration and concentration steps.

These columns feature BAKERBOND® DVB polymer resins, which are the product of ultra-clean polymer microparticle technology. These resin particles have a large surface area, are highly rigid, are stable over pH range 1 to 14, are water-wettable and are not impacted by sorbent drying. These columns are recommended when advanced detection methods are used.
