BioCoat is the new protective polyurethane cover developed by Instron - a business unit of Illinois Tool Works (ITW), which maintains a presence in Italy with ITW Test and Measurement Italia - for 5940 single-column testing instruments. These instruments are used for low-force in-vitro mechanical testing of biomaterials and components as well as materials for medical and biotechnological devices in temperature-controlled baths containing fluids such as water, saline solution, blood or products that simulate blood. The cover prevents the fluid from escaping the bath due to spills or leaks and damaging electronic components. It can be adapted to existing test instruments. All connections and controls are easily accessible and system functions are not altered. The extremely smooth surface also makes it easy to remove contaminating substances. The cover is resistant to the most common detergents.
