Photochemical/Photobiological Equipment Specifications The products in this catalog represent what we believe to be the most advanced design and construction. However, design improvements are constantly being made, and we reserve the right to modify specifications where we feel that a change is warranted. Apparatus fabricated in accordance with ASTM, API, AOAC and other technical organization specifications such as USP, NIST, and NIOSH, are subject to modification by these organizations. All precision-grade ware is warranted to be within the tolerance prescribed in ASTM Specifications. All...

Photochemical/Photobiological Equipment 7825 IMMERSION LAMP Photochemical (Medium Pressure)   Medium pressure, quartz, mercury-vapor lamp. For use in all ACE immersion wells. 61cm PTFE covered lead wires, fitted with pin type connectors. A 6-foot power cord also allows for lowering lamp into well for vertical operation. Approximately 40-48% of the radiated energy is in the ultraviolet portion of the spectrum, 40-43% in the visible region and the balance in the Infrared. Can be inserted into a glass well/sleeve with a 25mm I.D. For replacement cord, order 9698-10. Distance from Lamp to...

Photochemical/Photobiological Equipment 7835 ABSORPTION SLEEVES   Filter sleeve for use with all ACE Immersion Wells to restrict portions of the radiated energy from reaching the reactant material. An invaluable aid in predetermining which portion of the spectrum creates the reaction. Sleeves are glass, open end tubes which telescope into well assembly to surround the light source. For use with 100, 200, 450, and 1200 watt lamps, only. Type Glass Pyrex 7740 Pyrex 7740* *762mm long for 7885 pilot plant reactor. 7836 PHOTOCHEMICAL SAFETY REACTION CABINET*   This steel cabinet allows for the...

Photochemical/Photobiological Equipment 7861 REACTION ASSEMBLY Photochemical, Ace-Thred, Complete    Complete reaction assembly with all parts needed for immediate operation. Utilizes an internally threaded connection in place of the ground glass joint. Bushing and FETFE O-Ring form a compression type seal with immersion well. Well has removable inner cooling tube. Reactor has one-  14/20 angled joint for sparger tube, one-  24/40 vertical joint for condenser, and one-#7 Ace-Thred for thermometer. Volume indicated is total volume. Actual working volume is approximately 40-50% of total....
