New: PUR coating, autoclavable

In a special process, the highly transparent polyurethane-based coating is applied in defined film thicknesses to glass components, irrespective of their shape. The coating provides protection from light, impacts and scratches in everyday laboratory operations. In the event of glass breakage, the coating provides protection from shattering and leakage. We provide PUR coating on most of our laboratory glassware on request.
