Most applications will require pre-treatment prior to dialysis. As mentioned in the 'DESCRIPTION' section, under 'Preparation Note', for the removal of glycerol included as a humectant, wash the tubing in running water for 3-4 hours. To remove any residual sulfur, treat 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. Wetted membranes may be stored in water containing benzoic acid or formaldehyde.

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.
