DURAN® GLS-80 Jacketed Bottle with double walls and circulation ports, 500mL Clear, 2-Hose Connector. Screw Cap supplied complete with pouring ring, PBT GL 18 aperture caps and PTFE 10mm hose connectors. DURAN Double-walled wide mouth bottles with GLS-80 closure incorporate an integral jacket that isolates the contents from the external environment. Heated or cooled liquids can be circulated through the jacket to control the temperature within the screw topped bottle. Double walled bottles offer a sealable and more flexible alternative to open topped jacketed beakers.
