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.

Designed to maximise convenience and efficiency, the ready-to-use Micro Float-A-Lyzer® is ideal for the dialysis of very small sample volumes. Available in two volume sizes, 100 to 200 μl and 400 to 500 μl, the Micro Float-A-Lyzer® features a proprietary biotech grade cellulose ester (CE) membrane incorporated into a pre-assembled, leakproof microdialysis device. Available in 7 concise MWCO’s with colour-coded caps, CE is a synthetic, low-protein binding membrane with no heavy metal and sulfide contaminants. The pre-formed tubular geometry also limits volume increase and sample dilution. The self-standing and self-floating device is designed with a Luer-lok® sample port to provide quick and easy access for loading, in-process testing and total sample recovery using a 1 ml syringe (included). Available in packs of 12, individual units can interlock to form a "flotilla" for the simultaneous dialysis of multiple samples. Only Micro Float-A-Lyzer® and Float-A-Lyzer® G2 assure a 95 to 98% sample recovery, 98% sample purity and <10% sample dilution; all in an easy to use, convenient dialysis device.
