1pc 5 m/roll 8000-12000D Dialysis Bag MD44 Diameter 28mm Molecular Weight Cutoff 5m
The dialysis bag is a regenerated cellulose membrane (RC membrane), which is transparent, flexible, stable in performance and accurate in pore size.
1. Technical parameters of dialysis bag:
1. PH stability range: 2-122. Pollutant level: sulfide <0.3%; heavy metal <50ppm
3. Chemical compatibility: can withstand low concentrations of acid/base solutions, alcohols and organic solutions, including DMSO. Prolonged exposure to organic solutions may cause damage to the membrane.
4. Temperature resistance: can be boiled, can be autoclaved. Applicable water temperature: 4-121℃
5. Protein adsorption: The amount of protein adsorbed per gram of dialysis bag is less than 1ng.
2. Pretreatment and use of dialysis bags:
1. Select a dialysis bag of suitable size, and cut a small section with an appropriate length of usually 20-30cm according to the volume of the solution to be dialyzed, which can be processed several times at a time for use.
2. Weigh the EDTA of 0.292g and dissolve it in 1000mL of distilled water, take by weighing an appropriate amount of NaHCO , use NaHCO , adjust the pH of this solution to 8, place the dialysis bag in this PH solution and boil, after the solution boils, about Boil for 10 minutes.
3. After cooling, rinse the dialysis bag thoroughly with distilled water and store it at 4 degrees. Make sure that the dialysis bag is always immersed in the distilled water solution. Gloves must be worn when handling the dialysis bag from this point on.
4. For long-term storage, immerse the dialysis bag in 75% ethanol solution, and store it in a refrigerator at 4°C for later use.
5. Before use, fill the dialysis bag with water and drain it to clean it.
A more relaxed pretreatment scheme (this method may be recommended) can be used by boiling in distilled water for five to ten minutes and then washing with distilled water three times.

7. When in use, clamp one end with a dialysis bag clip. After filling with water, pressurize properly with your fingers to check that there is no leakage before loading the sample. Usually one-third to one-half of the space is left to prevent the bag from bursting due to excess water and buffer outside the bag entering the bag during dialysis. After filling the sample, clamp the mouth of the bag with a clip, and put a glass bead in the bag to make the dialysis bag in a suspended state, and then dialysis can be performed (see the diagram of the dialysis bag device for details). To speed up the dialysis, a magnetic stirrer can be used in addition to multiple changes of the dialysate. Dialysis containers are larger and can use large beakers, large cylinders and plastic buckets.
