Triple-walled, quartz, immersion well for use at temperatures as low as -78 ℃ . With 60/40 center inner joint. Outer two walls are permanently sealed together and the space between evacuated. This keeps lamp coolant water from warming the reactant and also prevents coolant water from freezing, thus lamp emits correct wavelengths and operates at optimum temperature for longer life. Innermost wall is held in place via a stopper and permits a carefully positioned, PTFE water inlet tube to extend below the lamp bottom. Inner tube is removable and may be interchanged with borosilicate glass tubes. One size tube fits both wells. Well is for use only with 7825 code -30, -32, -34 and -35 lamps. Outer chamber consists of a 7858-84 drilled neoprene stopper, 7855-740 spacer o-rings, metal water inlet, connecting tube and PTFE tubing.
Complete unit consists of quartz evacuated outer chamber, one each quartz and borosilicate glass inner tube and assembly Instructions.
