Its ability to selectively diffuse molecules across a semi-permeable membrane gives dialysis tubing its important place in classic laboratory technique. Dialysis is used for a wide variety of dialysis applications: desalting, buffer exchange, removal of labeling reagents, drug-binding studies, cell growth and feeding, virus purification, and blood treatment. Created from a natural source of cellulose, dialysis tubing provides a reliable source for separating molecules based on size for testing purposes, and no pre-treatment is required before use. Regenerated cellulose dialysis tubing is also available.

Tubes de dialyse, Float-A-Lyzer® G2
Supplier: Spectrum Laboratories
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.

Cassettes de dialyse, Slide-A-Lyzer®, Pierce®
Supplier: Thermo Fisher Scientific
Ces dispositifs peuvent être utilisés pour une large gamme d'applications, notamment l'élimination des contaminants de faible poids moléculaire, l'échange de tampon, la désalinisation, la dialyse à l'équilibre et la concentration. La membrane de la cassette est composée de cellulose régénérée de faible adsorption et est dotée d'un godet à échantillons hermétiquement fermé afin de conserver le plus longtemps possible les échantillons. Ce type de membrane est compatible avec un certain nombre de produits chimiques et de tampons. Les cadres transparents codés couleur de la cassette Slide-A-Lyzer® permettent une reconnaissance instantanée du MWCO de la membrane et facilitent la visualisation de l'aiguille pendant l'injection de l'échantillon.

Microdialysis devices, ready-to-use, Micro Float-A-Lyzer®
Supplier: Spectrum Laboratories
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.
