flowchem 1.1.1

Flowchem is a library to control instruments and devices commonly found in chemistry labs via an interoperable web API.

Welcome to flowchem

Flowchem is an application to simplify the control of instruments and devices commonly found in chemistry labs. Flowchem acts as unifying layer exposing devices using different command syntax and protocols under a single API.

Overview

Using flowchem is simple. You just need to create a configuration file with the connection details for your devices and run flowchem. The flowchem app then:

1. reads the configuration file with the devices to be controlled and their settings;
2. creates connections with each device and ensures a reproducible state at start-up;
3. provides access to the capabilities of each device (such as pumping, heating etc...) via a web interface.

Since flowchem leverages web technologies, flowchem devices can be controlled directly with a web browser or by clients written in different languages and from almost any operative system, including Android and iOS. A set of python clients interfacing with the flowchem API are also provided and used in examples.

Supported devices

Currently, the following instruments are supported:

• Pumps (Knauer P2.1, Harvard Apparatus Elite 11, Hamilton ML600)
• Valves (ViciValco and Knauer)
• Thermostat (Huber)
• Analytical instruments (Magritek Spinsolve benchtop NMR and Mettler Toledo FlowIR)
• General purpose sensors from Phidgets
• ... and more! We are open to contributions!
• If you want to add support for a new device, read how to do that in the documentation.

Install flowchem

To install flowchem, ensure you have Python >= 3.10 installed, then run:

pip install flowchem
