In research laboratories, dialysis technique can also be used to separate molecules based on their size. Additionally, it can be used to balance buffer between sample and the solution"dialysate" that the sample is in. For dialysis in a laboratory semipermeable membrane is used as a tube made of sentetik materials where pore size can vary according to the size separation required. Control over pore size allows a better separation between small molecules while leaving large molecules of interest inside. Solvents, ions diffuse easily through the pores while leaving the big molecules behind and separate.In protein purification technique dialysis is used to exchange buffers, loose smaller proteins that can pass through the pores, dilutions of concentrated salts, while leaving the protein of interest inside the semipermeable membrane separated.
The National Health Service provides dialysis in the United Kingdom. In England the service is commissioned by NHS England. About 23,000 patients use the service each year. NHS paid the cost of holiday dialysis in overseas.
Turkmed Dialysis Centers founded in 1997 in ıstanbul by Dr Basri YILMAZ, and now the group offers treatment service of 50.000 dialysis sessions annually to more than 350 patient who from different European countries. Turkmed Dialysis Centers have 65 hemodialysis and hemodiafiltration machines with Double RO Water Purification System.
