Duran 5414-139 500mL Graduated Bottle with Cap

Duran, 5414-139, Ace Glass 500mL Graduated Bottle with Cap

Heavy-wall borosilicate glass bottle with three PTFE valves with Tefzel keys. Pressure-tight PTFE coated Fluoron forms a seal within cap; hence, fluid contact is restricted to glass, PTFE and Tefzel. The three individually controlled valves permit the application of gas under pressure to the bottle for venting, flushing, or delivery of the bottle contents to one or two points. Bottles may be pressurized in isolation or in series with the other bottles. One of the valves may be used to allow corrosive fumes to be vented safely. Rated to 14 psig at ambient; must be adequately shielded when under pressure. Each bottle is provided with a three-valve, 1/4"-28UNF cap ideal for use with our 5859 and 5855 tubing connectors.
