UV-Visible exposure tools for controlled irradiation of a wide range of materials.This unit is recommended for customers who only use liquid samples and who therefore prefer side irradiation. The irradiation chamber is approximately 12 inches wide, 12 inches deep and 8.5 inches high. Two switches allow control of the lamps used (8 lamps, 4 each side). An exhaust is needed when using UVC (254 nm) lamps. Fan is included. Different wavelength ranges in the UV and visible regions are available. The irradiation chamber is air-cooled, and the air flow design stabilizes the temperature about 3-4 degrees Celsius above room temperature.
