Photoredox Catalysis & Parallel Synthesis

Illumination Devices
Taking advantage of recent breakthroughs in LED technology, Analytical Sales & Services is able to offer the next generation Lumidox II with higher optical/radiometric power than ever before. Lumidox II offers over 200 unique and complimenting photonic devices, in varying wavelengths, amplitudes and footprints. What took hours, now takes minutes. Reduce photochemical reaction time up to 40x while maintaining the same yield.

We offer apparatus in the following wavelengths:::
UV365, UV375, UV385, UV395, UV405, 420 (Violet), 445 (Indigo), 470 (Blue), 505 (Cyan), 527 (Green), 590 (Amber), 630 (Red), 660 (Deep Red), 730 (IR), White

Frequently Asked Questions - Collapse

What are the power and output of each LED, and the LED array as a whole?
See Stages and Radiant Flux Data Charts

What are the spectral outputs of the different wavelengths?
Typical spectral outputs can be found HERE. However, with each array or LumLamp, we provide a unique calibration document that notes this information, specific to the device. See an example of this document

What is the power/output difference between Gen I and Gen II arrays?
See Gen I vs Gen II Array Comparison

Are you able to modulate intensity?
Yes, modulating the output intensity is achieved by turning the front mounted dial to the desired output stage.

Does the controller include a “stopwatch” or timer feature?
Yes, an onboard illumination elapsed timer is provided, as well as a countdown to automatic shut off timer.

How efficient are the cooling fans on the active cooling base?
The efficiency of the cooling system is HIGHLY variable based on LED wavelength and type of reaction being catalyzed. As a general guide for informational purposes only, for the 5 default power levels, if starting out at ~20°C you can expect stage 1 to maintain a reactor block temperature of ~22°C, stage 2 to ~27°C, stage 3 to ~35°C, stage 4 to ~46°C, and stage 5 to ~60°C. For additional cooling capability, we suggest using a chiller with a cooling plate (utilizing a liquid coolant) on top of your reactor block.

Do I need an external cooling system for use with the solid base arrays?
The solid base (passive) arrays do require an external cooling source such as a chiller/cooling plate or dry cooling bath.

Do I need an external cooling system for use with the active cooling base arrays?
The active cooling base arrays have both fans, and a heat sink, so they can cool themselves.

Do I need an external cooling system for use with the LumLamps?
The LumLamp employs a modular heatsink system and is able to regulate temperature on its own.

Do you offer custom array calibration?
If you know what your optical power requirements are for a given wavelength, we can custom tune the units to your desired 5 stages.

Is there a way to continuously sweep the light intensity?
This is not currently possible as a custom option.

Do you offer light and heat mapping of the arrays?
Not at this time.

Who is the manufacturer of the LEDs?
We do not disclose this information, but can confirm that they are sourced from high quality manufacturers, and binned together for uniformity.

My unit turned off, is it broken?
Gen II arrays contain a resettable 100C fuse. If internal temperatures surpass this fuse, the unit will be temporarily prevented from illuminating. Power cycle the device and wait for the array to cool before operating. LumLamp units contain a single use thermal protection fuse. Fuse repair is not possible in LumLamp units.

What are STAGES?
Stages are radiometric output levels, of varying intensity, selectable by the front mounted controller dial.

What is the lifetime of the LEDs?
The LEDs have an approximate lifetime of 50,000 hours when operating under normal, ambient conditions.
