New Uniqsis Borealis™ Photoflow Reactor
The complete Borealis™ system comprises of the Borealis LED lamp unit, an FEP coil reactor, the Cold Coil™ standalone reactor module and a programmable power supply. Both the LED lamp and the reactor module require liquid cooling from either a piped water supply or a closed loop recirculator.
The Borealis™ LED Lamp Modules are available in standard wavelengths of 370, 410, 440, 460, 520nm with a maximum power output of 180W. The liquid cooled LEDs (connect to a water supply, MiniStat or Piccolo Peltier heat exchanger) fitted with quick connects and the wavelength is automatically detected when connected to the Borealis power supply. A safety interlock is fitted to prevent accidental exposure to high intensity light.
The coil reactor has a volume of 15ml using FEP tubing with standard ¼-28 HPLC fittings located in an inverted coil mandrel. The coil is fitted with embedded temperature sensors. The LED lamp is powered and the intensity controlled by connection to a custom power supply unit that automatically detects the wavelength of the Borealis LED module and adjusts the output characteristics accordingly.
Temperature control of the coil reactor is achieved using the Cold Coil™ Coil Reactor Module. Both the original version and the more recent updated Mk II versions are compatible with Borealis.
The coil reactor is inserted inside the Cold Coil reactor module and clamped in place using the external adjuster (to maximise thermal contact). The Borealis LED lamp 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 tap (for reactions close to room temperature only), or preferably to either a Huber Piccolo or Ministat recirculator.
