SIGMA/D9777 - avg. flat width 25 mm (1.0 in.)
Synonym: Cellulose dialysis tubing; Dialysis membrane
Product Type: Equipment/Book
| avg. diam. | 16 mm , when full |
| avg. flat width | 25 mm (1.0 in.) |
| capacity | ~60 mL/ft |
| Analysis Note: | May contain glycerin and sulfur compounds in more than trace amounts. |
| General description: | Typical molecular weight cut-off = 14,000. |
| Packaging: | Supplied in rolls, dry |
| 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. |
