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.

Supplier: G-Biosciences

The concentrator is a high molecular weight polymer which will not migrate across the dialysis membrane. The concentrator is placed against the dialysis membrane of the Tube-O-DIALYZER™, where it rapidly absorbs water from the sample and reduces the sample volume. The concentrator can be used with dialysis bags and other dialysis devices.

Supplier: Cytiva

The disposable tubes in mini dialysis kit offer a simple solution to the handling problems of small volume dialysis. The dialysis tubes in the kit each have a cap that incorporates a small disk of dialysis membrane.

Supplier: Thermo Fisher Scientific

Single-Use RED (rapid equilibrium dialysis) Plate is composed of disposable high-density polypropylene and is pre-loaded with 48 equilibrium dialysis membrane inserts. Each insert is comprised of two side-by-side chambers separated by an O-ring-sealed vertical cylinder of dialysis membrane with varying molecular-weight cutoffs (8 or 12 kD MWCO).

Supplier: Apollo Scientific

Non-ionic detergent used for membrane protein solubisation. An advantage of OG is its low molecular weight which allows easy removal by dialysis.

Supplier: Thermo Fisher Scientific

SnakeSkin dialysis tubings with pleated format are made from high performance regenerated-cellulose membrane which has minimal nonspecific binding and a reliable molecular-weight cutoff (MWCO).

Supplier: G-Biosciences

Dialysis is a routinely used technique in research laboratories to 'change' the solution a biomolecule is dissolved in. Often the buffers used to isolate biomolecules, such as proteins, are not compatible with downstream applications due to high concentrations of reagents, such as salts. A sample is placed in a bag with a semi-permeable membrane and then placed in the new solution or water. Small molecules, such as salt, can pass through the membrane, moving from an area of high concentration to low concentration. The larger molecules, such as proteins, are retained in the bag. Microdialysis is a modification of dialysis to overcome the problem of dialysing small volumes of precious samples. Microdialysis uses small devices designed for small volumes. This kit allows students to study dialysis using patented microdialysis devices.

Supplier: Thermo Fisher Scientific

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.

Supplier: Abcam

Zwitterionic non-denaturing detergent that protects the native state of proteins, able to disrupt non-specific protein interactions and has less protein aggregation than non-ionic detergents. It is electrically neutral and easily removed by dialysis. Often used in the solubilisation and purification of membrane proteins.

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.

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.

Supplier: Thermo Fisher Scientific

These devices can be used for a wide range of applications including low molecular-weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and concentration. The cassette membrane is composed of low-binding regenerated cellulose and features a hermetically sealed sample chamber to maintain the highest possible sample retention. This type of membrane is compatible with a number of common chemicals and buffers. The colour-coded transparent frames of the Slide-A-Lyzer® cassette allow instant recognition of the MWCO of the membrane and make viewing the needle easier during sample injection.
