Knurled knobs GN 676 are manufactured from an antibacterial plastic.

Adding a silver-based substance has created a natural active agent that helps to prevent the growth of bacteria. Even after repeated cleaning with soap or solvent, the antibacterial effect of this additive will not diminish. Sterilising at temperatures below 130 °C will also have no effect on the antibacterial property.

With these properties, the handles are the perfect choice for use in medical engineering, in the food and the pharmaceutical industry, and in general wherever hygiene is of great importance.
