For your photochemistry application the LED Conti flow & tube Photoreactor 500 is an ideal device to evaluate various wavelength and power levels when adapting light sources from conventional types to energy efficient LEDs. The larger design offers a varieties of set ups while the cavity has been designed to accommodate different  shapes of lab vessels like flask reactors, glass bulbs, Erlenmeyer flasks and test tubes with a filing capacity of up 2 liters and a diameter of up to 95 milimeters.

With multi-wavelengths 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.

LED Reactor System

The LED CONTIFLOW system covers a spectral range from 260 to 1100 nanometers. Up to eight wavelengths are combinable. The software control offers a 10bit intensity resolution. The system comes with an overheat protection and it includes LED degradation compensation.

Reactor Types

Modular containers such as sling flask reactor, glass bulb, erlenmeyer flask and test tubes with a filing capacity of up to 0.3 liters and a diameter of up to 95 milimeters are available so you can choose the ideal reactor geometry for your individual need and experimentel setup.


BIOspec modular spectrometers and accesssories comprise a flexible toolkit for chemists seeking to understand and monitor how light interacts with matter. Chemical composition, analyte concentration and molecular structure are all ready measured with spectroscopy. Easily configure setups for UV-Vis and NIR absorbance, fluorescence and Raman.


Choose and control single LED-systems as well as definied groups in your application. Adjust the spectrum as needed with10bit resolution. All data can be imported and exported from/to an excel controlled data base. Compose spectra and spectrum regimes to a scenario. The timer function comes with in-line brightness adjustment (rising/descending) or brightness curve.
