Photochemical Reactor as described in Journal of Chemical Education, Vol. 66, No. 1, January1989, pages 86-88. Unit incorporates all the features found in our larger units but is designed for carrying out reactions on a small scale, volumes of 5-15mL. This size translates to a reduction in the expense of start-up chemicals and minimal risk of exposure to hazardous materials or explosion.
Reactor body is fabricated of borosilicate glass with #25 Screw thread at top, 14/10 outer side joint externally threaded to allow an “O-Ring-CAP-SEAL" connection with mating inner joint, and porosity E (4-8 micron) filter disc at bottom for use as a gas inlet to remove oxygen from the solution and/or for agitation (mixing). Use with 3/8" or 7/16" I.D. Tubing, Size E. See page 5 for more detailed Hose Connection information.
Immersion well is either quartz or borosilicate, 11mm I.D., with water jacket. Well can also be used to flow filter solutions in front of lamp to attain desired wavelengths. Well is assembled by insertion into #25 Screw thread and securing with an O-Ring compression seal. This type connection allows volume adjusting by raising or lowering well inside reactor, volume range 5-15mL.
Recommended lamp for this unit is a Pen-Ray1 5.5 watt low pressure, cold cathode, mercury gaseous discharge made of double bore quartz; ACE No. 12132-08. Matching power supply operates at 115v, 60 Hz.
