Photoredox Temperature Controlled

PhotoRedOx Box TC  Description

The EvoluChem™ PhotoRedOx Box TC (Temperature Controlled) photoreactor (US Patent #10,906,022) enables photo-catalytic reactions at controlled temperatures between 0°C to 80°C. The design is based on our original PhotoRedOx Box which features a unique reaction chamber geometry that directs light throughout the chamber, allowing the performance of multiple reaction conditions simultaneously (between 2 and 32 depending on the reaction vial sizes). However, with the aluminum-based, waterproof PhotoRedOx TC, it is possible to heat and cool the reaction medium using a thermostatic fluid (such as water or ethylene glycol) that recirculates through a standard chiller/heater unit.

Features

  • Photochemistry chamber to evenly distribute light
  • Fits many light sources (EvoluChem 18W or Kessil blue 34W)
  • Flexible format vials (from 0.3 ml to 20 ml)
  • Photochemistry chamber to evenly distribute light
  • External recirculator needed to heat or chill reaction vessel
  • Flow reactor available
  • Magnetic stirring on standard stirring plate

Featured Heater/Chiller Unit

Julabo Corio 200F

While most common chiller/heater units can be used with the PhotoRedOx Box TC, for USA/Canada clients we can offer the Julabo Corio 200F unit which works perfectly with our instrument.

Light Temperature Effect on Conversion

Isopropyl Molander

Experimental Details:
Reaction performed in Evoluchem Photoredox Temperature control bath with circulating polyethylene glycol/water bath and an EvoluChem 18W 6200K white light for 2 hr. Reaction contains 50 µmol substrate, 1.5 equiv. RBF3K, 2 equiv. K2S2O8, 5 equiv. TFA and 2 mol% Ir(dF-CF3-ppy)2(dtbpy) in 0.5 ml DMSO.

Light transmission in fluids:
We investigated the possible influence of liquids on the light transmission. Water or ethylene glycol do not affect photoredox experiments.

Photocatalysis in Seawater

Seawater: It’s abundant, messy, contains salts, microorganisms, biomass, organic and inorganic pollutants (and microplastics) and might just be a great solvent for generating hydrogen peroxide with visible light photocatalysis
