# Wisconsin Photoreactor Platform (WPP)

An open source photoreactor platfrom. 3D printed enclosure, commercially avaliable components, and a little bit of custom circuitry.

![WPP photo](./coverart.png)

A WPP device consists of a base, reaction module and reactor driver. The base houses the photon source and cooling fan. The reaction module consists of a  reaction chamber and  vessel holder. A digital driver board, analog driver board or simple circuit integrating a commercial light emitting diode (LED) driver can be fitted to the base to drive the reactor. Each component is highly versatile, and apparatus is fully modular.

## Safety

The Wisconsin Photoreactor is for use by trained chemistry researchers and should be handled carefully.

WPP apparatuses utilize high-intensity light emitting diodes (LED) that can cause eye damage if proper safety precautions are not observed. 
Light-filtering safety glasses should be worn whenever a WPP apparatus photon source is powered. 
Care must be taken to use safety glasses protective against the specific emission wavelengths of a photon source.

## Frabication and Operation Instructions

This repository contains detailed instructions for fabrication, operation and documentation of WPP devices.
Please see [wpp-assembly.pdf](./assembly-instructions/wpp-assembly.pdf)

## Enclosure

The WPP is designed around a mechanically robust 3D printed enclosure.
Every WPP device has the same base, see directory `photoreactor-base`.
WPP reaction modules are meant to be switched based on the reaction vessel used.
See directory `photoreactor-tops` for our growing collection of reaction modules for common vessel types.

## Electronics

The WPP incorporates small custom circuit boards providing control over light intensity and fan speed.
Please see the fabrication instructions for more detailed information.
