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.

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.

Slide-A-Lyzer MINI Dialysis devices, 3,5K MWCO, are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules >3,5 kDa in volumes from 10 µl to 2 ml. They were developed as a convenient means for dialysing small-volume samples of nucleic acids and proteins without undue sample loss. Low molecular weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, micro conjugation reactions, and concentration can be accomplished with these devices.

La cassette de dialyse Slide-A-Lyzer® G2 offre efficacité, confort et protection de l'échantillon dans un seul kit. Le chargement et le retrait de l'échantillon sont réalisés facilement à l'aide d'une pipette sérologique ou d'une aiguille hypodermique fixée à une seringue. La chambre d'air intégrée assure la flottabilité de l'échantillon et l'orientation verticale de la cassette au cours de la dialyse.

KrosFlo® hollow fibre membranes for implant technology provide a true-to-life response for drug screening and cancer research. Perfectly suited for implantation, the modified Polyvinylidene Difluoride (mPVDF) hollow fibre membrane is biocompatible, resistant to cell adhesion, hydrophobic and resistant to a wide variety of organic solvents, including most aqueous acids and bases. Furthermore, these hollow fibres can be heat sealed and autoclaved without affecting the molecular weight cut off (500 kDa MWCO) or changing the membrane performance.

MWCO 12 - 14 kD, regenerated cellulose

Supplier: Spectrum Laboratories

Disposable and ready-to-use dynamic dialysis device.

Supplier: Spectrum Laboratories

Biotech RC (Regenerated Cellulose) dialysis tubing is crafted from a regeneration process that yields superior temperature tolerances and chemical compatibilities with the same high purity and selectivity as Biotech CE. RC membrane can tolerate concentrated-weak acids & bases, dilute-strong acids and bases, most alcohols and some mild or dilute organic solvents. Exposure to strong polar or organic solvents may damage RC membranes. Use with pH 2 - 12 and temperature 4 - 60 °C.

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.
