Photochemical Reactors
REACTION SYSTEM #50 Ace-Thred, 450W
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 (1) 14/20 angled joint for sparger tube, (1) 24/40 vertical joint for condenser, and (1) #7 Ace-Thred for thermometer. Volume indicated is total volume. Actual working volume is approximately 40-50% of total.
REACTION SYSTEM Standard Taper, 450W
Complete reaction assembly with all parts needed for immediate operation. Borosilicate glass reactor has a 60/40 center joint, (1) 14/20 angled joint for sparger tube, (1) 24/40 vertical joint for condenser, and (1) #7 Ace-Thred joint to accommodate thermometer. Volumes indicated are total volumes. Volume in reactive area of lamp is 40-50% of the total volume.
PHOTOBIOLOGICAL-OXIDATION APPARATUS 1200W, U.V., Flow-Thru
Modified version of 7900 Apparatus. Sample tubes have been replaced with a flow-thru quartz or borosilicate coil for continuous radiation of small (as little as 175mL) or large samples. Coil is available with cooling jacket for slow flow rates or without jacket when heating of sample is not a concern because of the higher flow rate.
Apparatus consists of a cylindrical lamp housing, medium pressure 1200 watt photochemical lamp, quartz or borosilicate glass coil (with or without jacket), and power supply. Access door is provided for set-up, inspection and repairs only — for your safety, do not use this door while the unit is in operation.
A cooling fan is located at bottom of housing for air movement. Lamp power supply includes a manual or automatic twelve-hour timer selector for programming exposure time. Available in 220v, 60Hz or 230v, 50Hz. Lamp housing measures 12” wide x 20” deep x 36” high, and weighs 75 lbs. Power supply measures 11” wide x 18” deep x 11” high, and weighs approximately 75 lbs. Coil is 12.7mm O.D. x 8.0mm (5/16”) I.D. with 1/2” Swagelok ends, 16 ±1 turns with approximate capacity of 175mL, maximum flow rate of 10L/min.
PHOTOBIOLOGICAL-OXIDATION APPARATUS 1200W, U.V.
Standard unit for liberation of inorganic phosphate from organically bound phosphorus compounds, oxidation of carbon inorganic matter and oxidation of organic nitrogen compounds. Oxidation of organic compounds in water and sediment samples is accomplished by exposure to ultraviolet radiation in the presence of excess oxygen. Organically bound phosphorus is liberated as the ortho-phosphate in as little as one hour. Organic matter is oxidized to CO2. Nitrogen compounds are oxidized to the nitrate and nitrite ions.
Additional applications include decomposition of organometallic compounds, providing organic-free samples for culture, nutrition and vitamin assay, destruction of algal suspensions, and oxidation of sediment or residue samples.
Apparatus consists of a cylindrical lamp housing with twelve-position sample tube chamber for twelve quartz tubes of approximately 100mL capacity that surround a 1200 watt medium pressure photochemical lamp. Access door is provided for set-up, inspection and repairs only — for your safety, do not use this door while the unit is in operation.

ACE heavy wall borosilicate glass Pressure Reactors have been designed and tested to provide the chemist with a system to perform low to moderate positive pressure reactions, synthesis, and catalysis; or simply to run reactions under inert gas conditions. Reactor capacities range from 500mL to 5000mL, and use Ace‑Threds to achieve a leak-tight system.
Two types of Pressure Reactors are available:
- 1— Two-Piece System, with a maximum pressure limit of 35psig @ 100°C
- 2— One-Piece System, with a maximum pressure limit of 45psig @ 100°C
The Two-Piece System consists of a flanged flask and head with a shallow O‑Ring groove, O‑Ring, and quickrelease clamp. Flange sizes range from 60mm to 150mm inside diameter, allowing the use of large agitators and facilitating product removal and clean-out. Both systems offer jacketed and unjacketed vessels, with or without bottom outlet valves. These jackets are heat-sealed.
Complete systems and their components are listed on the following pages. Systems are available with:
- Liquid addition funnel
- Solid addition funnel
- Stirring motor, controller and flexible shaft
- Heating mantle and temperature control system
- Thermowell
- Moisture test receiver
- Temperature controller with thermocouple
- Pressure relief manifold
- Support Stands
LAMP Medium Pressure Medium pressure, quartz, mercury-vapor lamp. For use in all listed immersion wells. 61cm PTFE covered lead wires, fitted with pin type connectors and 6’ cord for connecting to power supply, permit lowering lamp into well for vertical operation. Of total energy radiated, approximately 40-48% is in the ultraviolet portion of the spectrum, 40-43% in the visible, the balance in the infrared.
