Filtryzer BK-U(Catalog)


Filtryzer BK-U (PMMA membrane) offers excellent biocompatibility, and it gives higher performance for the removal of small and middle molecular weight substances, and efficiently removes of low molecular weight(LMW)protein, such as β2-MG by adsorption.


This device is the hollow fiber dialyzer which shall be used in acute or chronic hemo dialysis treatment in order that renal failure patients could remove the excessive water in the body and uric toxins sucha as urea, creatinine, phosphate, β2-MG, etc.
