Microchannel Photoreaction Devices: Plate-Type and Multiphase Microchannels | Perfectlight

1. Why Microchannels Suit Photochemistry

Photochemical reactions are sensitive to optical path and mixing. The thin-layer structure of a microchannel lets reactants receive light fully and exchange heat rapidly, avoiding the uneven illumination and local overheating of traditional batch reactors—ideal for fast, controllable photochemical synthesis.

2. Plate-Type Microchannel: PLR PMCD-G20

The PLR PMCD-G20 Plate-Type Microchannel Photoreaction Device adopts a flat sandwich structure with a large transparent face and short optical path, suited to liquid-phase photochemical synthesis and continuous-flow reactions. Its modular design eases series connection of multiple stages for continuous photochemical production.

3. Multiphase Microchannel: PLR-SMCR1000

The PLR-SMCR1000 Multiphase Microchannel Reaction System targets gas-liquid-solid multiphase systems, achieving efficient three-phase contact inside the microchannel—suited to photocatalytic degradation, photohydrogenation, and other multiphase photoreactions, with mass transfer far above batch reactors.

4. Selection and Notes

  • For pure liquid-phase reactions, choose the plate-type PLR PMCD-G20;
  • For gas-liquid-solid multiphase, choose the PLR-SMCR1000 multiphase microchannel;
  • For both, watch the alignment of light source and channel to ensure the effective optical path is fully used.

Frequently Asked Questions (FAQ)

Why are microchannels good for photochemistry?

Their thin-layer structure gives full light exposure and rapid heat exchange, avoiding the uneven illumination and local overheating common in batch reactors.

What is the PLR PMCD-G20 for?

It is a plate-type device with a large transparent face and short optical path, ideal for liquid-phase and continuous-flow photochemical synthesis.

How do I choose between the two?

Pick the PLR PMCD-G20 for pure liquid-phase reactions and the PLR-SMCR1000 for gas-liquid-solid multiphase systems, while ensuring proper light-source-to-channel alignment.
