The housing material of any FX Dialyser is made of environmentally friendly and lightweight polypropylene. Due to the advanced material, FX Dialysers are up to 50% lighter (before treatment) than dialysers made of polycarbonate.8

The reduced weight of an FX Dialyser may improve the end-of-life management by producing up to 1,600 kg less waste9 per year for an average dialysis clinic, also contributing to cost savings.

Each FX Dialyser is individually sterilised by the unique INLINE steam sterilisation method. Both the blood and the dialysate compartments of the dialyser are rinsed continuously with steam at a minimum temperature of 121° C. Rinsing with hot steam assures a gentle sterilisation without the need for chemicals or irradiation, which may lead to increased cytotoxic10 and carcinogenic residuals.11,12

Moreover, cytotoxicity is minimal after steam sterilisation, whereas it increases with gamma irradiation.16 Studies have shown that with steam sterilised dialyser membranes, less oxidative stress is induced to the patient’s blood, compared to gamma sterilisation.13,14,15

In addition, changes of the material properties can be observed after sterilisation with gamma irradiation, while the material remains intact when using steam sterilisation.16 Moreover, the elution of PVP from the dialysis membranes was lowest for dialysers sterilised with INLINE steam and highest for autoclave steam sterilised dialysers.2 Increased losses of albumin during dialysis sessions have been observed with gamma sterilised dialysers which had been stored for a longer time.10,17

The unique microwave fibre structure enables the homogenous distribution of dialysis fluid, supported by the inner housing’s pinnacle design of all FX Dialysers. This prevents the channelling of the dialysis fluid and ensures that each fibre within the bundle is surrounded by the dialysis fluid, contributing to improved clearances.5,6,7

The characteristic blue FX Dialyser header, with its laterally placed blood inlet port is designed to reduce the risk of kinked bloodlines, aiming at smooth handling.

The improved header design of FX Dialysers ensures a homogenous blood flow path. Its geometry allows a spiral distribution of blood in the dialyser header, preventing low-velocity stagnation zones and resulting in an enhanced performance.5
