High intensity LED module for photochemical flow applications

3-Nov-2021

The lamps are powered by a programable power supply that automatically detects the wavelength of the Borealis module and adjusts its output characteristics accordingly

Borealis from Uniqsis is a new high intensity LED lamp unit, available in a range of fixed wavelengths (370, 410, 440, 460 and 520nm), that converts the company's Cold Coil standalone reactor module into a flow reactor for photochemical applications.

Both the Borealis and the Cold Coil modules require liquid cooling from either a piped water supply or a closed loop recirculator.

Fitted with a safety interlock to prevent accidental exposure to high intensity light, the lamps are powered by a programable power supply that automatically detects the wavelength of the Borealis module and adjusts its output characteristics accordingly. A temperature sensor and safety cut-out are fitted to protect the LEDs from overheating. An inert gas purge input is provided for low temperature use.

To operate as a turn-key photochemical flow reactor system, a coil reactor is inserted inside the Cold Coil module and clamped in place using the external adjuster. The Borealis unit is then inserted into the coil reactor and connected to the power supply.

The coil reactor temperature is controlled by connecting the Cold Coil to either a cold-water supply (for reactions close to room temperature), or preferably to a high precision thermoregulation system.
