General description

Typical molecular weight cut-off = 14,000.

Packaging

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.

Analysis Note

May contain glycerin and sulfur compounds in more than trace amounts.
