Ace Glass is pleased to announce the addition of new round bottom pressure flasks to our already extensive line of pressure vessels. These heavy-wall flasks have a rounded bottom to facilitate use in heating mantles, and for other round bottom flask applications. These flasks have a PTFE front-seal plug for better sealability with FETFE O-Rings. Model 8417 flasks feature a side thermowell to accommodate either temperature sensors or thermometers. These flasks are rated @ 60 psi maxium up to 120°C. Safety coated versions are available upon special request.
