For your photochemistry applications the LED Conti flow & tube Photoreactor 200 is an ideal device to evaluate various wavelengths and power levels when adapting from conventional light sources types to energy efficient LEDs. The compact design enables an easy lab use while the cavity has been designed to accommodate various shapes of lab vessels like flask reactors, glass bulbs, Erlenmeyer flasks and test tubes with a filing capacity of up to 0.3 liters and a diameter of up to 95 milimeters.

With multi-wavelength you can test which wavelength provides in your process the best results. The single wavelength reactors offers maximum power to gain understanding how long it will take to process your chemistry, how fast it may flow and how much light intensity you really need.
