EMPEH antithrombogenic low-friction coating The transparent EMPEH coating, here applied to the inner surface of PVC infusion tubing, turns purple, when stained with toluidine-blue O.	EMPEH Heparin-based anti-thrombogenic coating with low-frictrion properties. Designed for the inner surface of (polymeric) catheter and infusion tubing, including PVC. Ideal for reduction of friction between balloon catheter and guide wire both for PTA and PTCA application. Frictional behaviour is between that of high density polyethylene (HDPE) and PTFE, but in this case with added anti-thrombogenic properties to prevent increase of friction by (starting) thrombus formation. Very low particle risk; this is not a hydrogel. Friction properties work both under wet and dry conditions. The coating purely consists of biocompatible materials (ISO-10993).	more..
IoHep heparin coating The transparent IoHep coating turns purple, when stained with toluidine-blue O. The top three tubes are coated on both the in- and outside. The bottom tubing is uncoated. The top sample is stained on both in- and outside, whereas the second tube from the top is stained on the inside only.	IoHep Anti-thrombogenic coating with ionically-bound heparin, designed for polymeric surfaces of medical devices. Applicable to non- and low-sweating surfaces such as nylon, linear polyurethanes, polyethylene and some silicones. The coating forms a perfect barrier between blood and device. Extremely little leaching of heparin into the blood and no risk of particle generation. Suitable as lumen coating for catheters. Fully biocompatible (ISO-10993).	more..
CovHep heparin coating The transparent CovHep coating, here applied to an intra-ocular lens, turns purple when stained with toluidine-blue O.	CovHep Coating with covalently-bound heparin. The coating is designed for various polymeric medical devices. The layer is somewhat thicker than the IoHep coating (see above) and can be exposed to harsher biological conditions. There is extremely little leaching of heparin into the blood. The coating purely consists of biocompatible materials (ISO-10993).	more..
