Product Description
When bottles go through repeated autoclave cycles or dry-heat sterilization, standard caps can warp or crack. These red high-temperature screw caps and pouring rings are built to stay dependable at elevated temperatures while sealing tightly against aggressive contents. They are a dependable upgrade for labs that sterilize glassware often.
This listing is for DURAN catalog number 292442802: GL 45 High Temperature Pouring Ring, ETFE, red, Pack of 10. The caps are molded from glass-fiber-reinforced PBT and fitted with a PTFE-coated, peroxide-cured silicone liner that faces the bottle contents. Matching ETFE pouring rings provide clean, drip-free dispensing. Caps come in GL 14, GL 18, GL 25, GL 32 and GL 45 sizes, pouring rings in GL 32 and GL 45, and all components autoclave at 121 or 134 C. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
