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.

準備報告
通过在流水中洗涤管3-4小时，可以除去用作保湿剂的甘油成分。 通过使用0.3％（w/v）硫化钠溶液在80℃下处理管1分钟，可以除去硫化合物。 用热水（60℃）洗涤2分钟，再用0.2％（v/v）硫酸溶液进行酸化，然后使用热水冲洗以除去酸。 该管可保留大多数分子量为12,000或更高的蛋白质。

can it seprate 5 nm gold particle from gold solution
1 answer-
If the particle is larger than the tubing's 14 kDa molecular weight cut-off (MWCO) rating, it should be retained.
