RCT Reichelt Chemietechnik

Dialysis tubing enables gentle desalting, purification and concentration of sensitive biological materials through semipermeable membranes with defined separation limits. The process is based on controlled diffusion of ions and small molecules while retaining high molecular weight substances.

Material Diversity for Specific Applications

Cellulose acetate (CA) tubing of the Standard series offers a medium pore size of 25 Angstrom with a nominal molecular weight cut-off of 15,000 Dalton. Cellulose hydrate variants of the Rapid series ensure 20% higher dialysis speed with identical separation properties. Cellulose ester tubing is completely free from heavy metal and sulfur compounds and is particularly suitable for sensitive applications.

Defined MWCO Values and Dimensions

The available Molecular Weight Cut-Off values cover the range from 0.1 kD to 1000 kD and enable precise separation processes. The seamless membranes are offered in flat widths from 4 mm to 148 mm and lengths of 3, 10 and 15 m.
