How to Choose a Photochemical Reactor? Rotary vs Multi-Channel | Perfectlight

1. The Fundamental Difference Between the Two Types

AspectRotary Photochemical ReactorMulti-Channel System
Illumination modeSample rotates around the lampFixed positions under one light path
Best forSingle-sample long runsCross-comparison & screening
Trade-offLower throughputLess fine per-channel control

A rotary photochemical reactor moves the sample around the light source so it is evenly illuminated by motion—ideal for long single-sample reactions and uniform irradiation. A multi-channel system runs multiple samples in parallel under one optical path, suited to lateral comparison and screening. Selection essentially comes down to "depth or breadth."

2. Rotary Type: PLS-P8 and PLS-P12

The PLS-P8 Rotary Photochemical Reactor and the PLS-P12 Rotary Photochemical Reactor provide 8-tube or 12-tube rotary arrays with a simple structure and easy maintenance, making them common platforms for teaching and single-point reactions. They are highly compatible with light sources and can be paired with a Xenon Lamp Light Source, LED, and other irradiation units.

3. Multi-Channel: A Tool for Parallel Screening

The PCX-50C Discover Multi-Channel Photocatalytic Reaction System pushes "breadth" to the limit, running dozens of reaction positions in parallel at once—especially suited to catalyst-library screening and condition scanning. The trade-off is relatively limited fine temperature-control space per channel.

4. Selection Advice

  • For mechanism studies and single-sample long runs: choose the rotary PLS-P8/P12;
  • For catalyst screening and condition cross-evaluation: choose the PCX-50C multi-channel;
  • Both are advised to pair with the MCP-WS1000 Photochemistry Workstation for unified management and recording of experimental parameters.

Frequently Asked Questions (FAQ)

What is the fundamental difference between rotary and multi-channel reactors?

Rotary reactors rotate the sample around the lamp for even single-sample irradiation; multi-channel systems run many samples under one light path for parallel comparison. The choice is depth versus breadth.

What do the PLS-P8 and PLS-P12 offer?

They provide 8- or 12-tube rotary arrays with a simple, easy-to-maintain structure, widely used for teaching and single-point reactions, and are compatible with xenon, LED, and other light sources.

How should I make the final selection?

Pick rotary PLS-P8/P12 for long single-sample mechanism work, the PCX-50C multi-channel for screening, and pair either with the MCP-WS1000 Photochemistry Workstation for unified data management.
