Regenerated cellulose membranes are typically compatible with acids and alcohols. Organic solvent compatibility varies from compound to compound. However, the solvent concentration, temperature, and exposure time are factors to be considered. Please see the table below to review the general membrane compatibility with various solvents.

General description
Typical molecular weight cut-off = 14,000.
Packaging
Supplied in rolls, dry
Quality
May contain glycerin and sulfur compounds in more than trace amounts.
Preparation Note
Removal of glycerol included as a humectant can be accomplished by washing the tubing in running water for 3-4 hours. Removal of sulfur compounds can be accomplished by treating the tubing with a 0.3% (w/v) solution of sodium sulfide at 80°C for 1 minute. Wash with hot water (60°C) for 2 minutes, followed by acidification with a 0.2% (v/v) solution of sulfuric acid, then rinse with hot water to remove the acid. This tubing will retain most proteins of molecular weight 12,000 or greater.
