Photoreactors, LEDs and Accessories

Photochemistry is a powerful tool for chemical synthesis and a variety of conditions have been reported in the scientific literature using a wide range of catalysts and reagents. Therefore HepatoChem offers a number of proprietary and advanced photoreactors as well as a number of screening kits and accessories to explore photochemical conditions.

Above: Our short video demonstrates the main features of the PhotoRedOx Box

EvoluChem™ Brand Photoreactors

photoreactor

PhotoRedOx Box

Our original photoreactor, this patent-pending device is compatible with most vial formats (0.3 ml, 2 ml, 4 ml and 20 ml vials) and is compatible with most stirring plates. A built-in fan keeps the reaction conditions at room temperature.  Several light source options are available.

photoredox duo photoreactor

PhotoRedOx Box Duo

The PhotoRedOx Duo uses the same unique design as our original photoreactor but doubles the vial capacity and includes an additional reaction chamber. The photoreactor Duo can hold up to 16 vials (2, 4 or 8 ml) and can accommodate a second light source for increased reaction rates of difficult reaction conditions.

Temperature controlled photoreactor

PhotoRedOx Box TC (Temp Controlled)

Also based on our original photoreactor, the TC version, with a standard chiller/heater unit (not included), makes possible to perform photo-catalytic reactions at controlled temperatures from 0°C to 80°C.

Flow Photoreactor

PhotoRedOx Flow Reactor

Our specially designed flow reactor (meant to be used with our PhotoRedOx Box) enables scaling of photochemistry reactions by significantly increasing surface area.  This flow reactor uses PFA tubing and has volume of 2 ml. 

 

EvoluChem™ Brand LEDs

EvoluChem LEDs

EvoluChem™ LEDs are designed specifically for photo-catalytic chemistry applications. They fit all EvoluChem™ PhotoRedox boxes and are designed to irradiate samples with maximum efficiency.

The commercial-grade LED chips are selected for specific wavelengths and are offered at the following levels: 365 nm, 380 nm, 405 nm, 425 nm, 450 nm, 475 nm, 525 nm, 650 nm, 740 nm, and 6200K white.

RED and NIR LEDs

Our latest addition to the family of EvoluChem LEDs is our 650PF (pictured above) which enables red light photochemical reactions.  We also offer 740nm NIR.  

We examine several advances in Red Light Photochemistry here.

DX Format LEDs

While most of our LEDs are standard (Par) format, our DX series LEDs are fitted with a more powerful 30W power supply but still fit all EvoluChem™ Photoreactors.

Accessories

Light Protection

High-powered LED light sources, particularly in the UV spectrum, are known to be damaging to your eyes.  We offer special glasses and safety screens to protect your eyesight during reactions.

We also offer hoods for your vial holders to eliminate light from outside the reaction chamber.

Photoreactor Vial Holders

These holders are designed for our PhotoRedOx Box HCK1006-01-016, our PhotoRedOx DUO HCK1006-01-023, and our PhotoRedOx TC HCK1006-01-025. They are compatible with most vial formats (0.3 ml, 2 ml, 4 ml and 20 ml vials). (Patent Pending)
