The red pouring rings made of PBT are the perfect complement to the clear and amber laboratory glass bottles with GL45 thread. Delivered with a PTFE-coated silicone seal, they are temperature-resistant up to 200°C. Therefore it is possible to sterilize them with hot air at 180 °C. Evaporation of highly volatile substances is avoided by the additional seal.
