Dialysis Membranes / Tubing

Dialysis Membranes from high quality regenerated cellulose

 
 

Dialysis membrane tubings are made of high quality Regenerated Cellulose. They are produced with the highest care and attention to quality and stability. Still, they are extremely cost effective. The membranes are supplied dry containing glycerol acting as a preservative. Thus, the membranes should be cleaned before use.

To further help the user in his lab, each box includes:
  • Two free of charge dialysis membrane clips
  • Technical manual
  • Analytical data sheet (except D14b range)
membrane clips

Regenerated Cellulose Dialysis Membranes Datasheet/Manual

 
Dialysis Membrane regenerated Cellulose In order to prevent any damage to the membranes during transport, the membranes are packed in a carton. This carton is packed in a seal bag containing a desiccant and the bag is packed in another thick carton box.

A membrane MWCO size should be chosen as high as possible in order to achieve the maximum dialysis rate and to prevent the loss of the desired solute.

The dialysis process

Dialysis is the process of diffusion of solutes through a semi-permeable membrane from an area of higher concentration on one side of the membrane to a lower concentration on the other side. The membranes are semi-permeable because they allow some molecules to pass while preventing others from passing. The process has long been used for the separation of low molecular weight molecules from macromolecules.
 

This relatively simple process is desirable and effective for several reasons:

• Wide Range of Sample Volumes

• Gentle Conditions

• Inexpensive Membranes and Equipment 

Common dialysis applications utilise tubular forms of membranes and involve placing a “sample” inside the membrane and a “buffer” outside the membrane. The process is run until equilibrium is attained. Molecules larger than the pores will remain on the sample side while all molecules smaller than the pores will be equally distributed between the two sides.

Usually, a very large volume of buffer is chosen so that the permeable species are greatly diluted and therefore reduced to very small concentrations in the remaining sample solution.

Commonly, dialysis processes require several hours to complete.

Dialysis membranes are characterised by molecular weight cut off (MWCO) MWCO is determined by testing the degree of permeability for several solutes of different molecular weights. MWCO is the molecular weight of the smallest solute that is retained to an extent of 90% in a 17 hour dialysis test.

CHEMICAL COMPATIBILITY

Regenerated cellulose has excellent resistance against organic solvents. Chemical compatibility can be influenced by various factors, and we recommend that you confirm compatibility with the liquid you wish to use by performing a trial run before you begin with actual dialysis.

 

Classifications:

G - Compatible

F - Limited compatibility (swelling or shrinkage may occur)

N - Not compatible
