Dialysis and Desalting

Slide-A-Lyzer MINI Dialysis Devices, 10K MWCO, are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules greater than 10 kDa in volumes from 10 μL to 2 mL.

The Slide-A-Lyzer G3 Cassettes are single-use dialysis devices designed to maximize performance and practicality. They provide an easy-to-use and secure alternative to traditional dialysis tubing and are used in a wide range of applications including low molecular-weight contaminant and salt...

The new and enhanced Thermo Scientific Zeba Spin and Micro Spin Desalting columns and plates are specifically designed for efficient desalting and buffer exchanging proteins with a molecular weight >40 kDa and removing small molecules less than 2 kDa.

Rapidly desalt protein and biological samples for manual or automated liquid chromatography (LC) with Thermo Scientific Zeba Spin Desalting columns, plates, and cartridges, which enable ≥95% retention of salts and other small molecular contaminants (<1,000 Da).

Slide-A-Lyzer Dialysis Flasks (2K, 3.5K, 10K, or 20K MWCO) facilitate simple and effective removal of buffer salts and small contaminants in sample volumes up to 250 mL. They are easy to use: add and remove sample using a serological pipette or by directly pouring the sample through a wide screw-cap...

Slide-A-Lyzer MINI Dialysis Devices, 20K MWCO, are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules >20 kDa in volumes from 10 μL to 2 mL.

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 >3.5kDa in volumes from 10 μL to 2 mL.

Float Buoys for Slide-A-Lyzer™ MINI Dialysis Devices contain inert, low-density polyethylene (LPDE) construction that is compatible with most aqueous buffer conditions, and the floats can be washed and reused.

Slide-A-Lyzer Dialysis Cassettes (3.5K MWCO) facilitate simple and effective removal of salts and small contaminants from proteins and other macromolecules larger than 3,500 Daltons. They can be used for a wide range of applications including low-molecular weight contaminant removal, buffer...

Slide-A-Lyzer Dialysis Cassette Syringes are designed for efficient loading of samples into Slide-A-Lyzer cassettes and removal of sample after dialysis. Cassette Float Buoy accessories are for use with Slide-A-Lyzer Dialysis Cassettes used to remove low molecular weight contaminants and perform...

The SnakeSkin 3.5K, 7K, and 10K MWCO dialysis tubing is an easy and ready-to-use traditional dialysis membrane tubing that allows desalting and buffer exchange for samples of 10 to 100 mL. SnakeSkin Dialysis Tubing Clips are sturdy, non-floating tube closures recommended for use with SnakeSkin...

Quickly remove non-reacted fluorescent dyes, biotin, reducing agents, and crosslinkers from protein samples with a 7K MWCO in fewer than 15 minutes with Thermo Scientific Pierce Zeba Dye and Biotin Removal columns and filter plates.

Slide-A-Lyzer MINI Dialysis Devices, 7K MWCO, are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules larger than 7,000 Daltons in volumes from 10 to 100 μL.

Desalting and buffer exchange are two of the most widely used applications in resin filtration chromatography. Thermo Scientific Pierce Polyacrylamide Spin Desalting Columns, 7K MWCO (molecular-weight cutoff), are ready-to-use, disposable, gel-filtration columns for the separation of proteins and...
