Description générale
Typical molecular weight cut-off = 14,000.
Conditionnement
Supplied in rolls, dry
Qualité
May contain glycerin and sulfur compounds in more than trace amounts.
Notes préparatoires
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.
