Waters 515 Pump with Custom Bluetooth Control Hardware & Python Script - Ready to Use!

I hope that this may be of interest to fellow analytical chemists...I created some hardware that can interface with a Waters 515 pump and send it commands via Bluetooth from a laptop. The hardware (a small microcontroller module that I add inside of the pump) can "press" the front panel control buttons, thus with the right sequence of button depressions it can basically access any pump function or setting but controlled from a python script. The installed module also transmits the pump pressure (and soon the motor current too, but not in this unit). I created this pump upgrade because I wanted to run some gradient pump rate profiles for my experiments. This ready-to-use setup is ideal for laboratory and research professionals seeking precision management and remote control for liquid chromatography. You likely are checking out this listing because you already know that the Waters 515 HPLC pump is the gold standard for reliable run to run control, now you can access programmability without requiring Waters controllers or software. An example GUI is available free for download from my GitHub repository, the python files can be used to customize your own controller software too. I'm also open to modifying the software for your specific application too, just let me know what you'd like to do.

Key Features:

Fully Installed Bluetooth Hardware: No additional setup required—simply plug in the pump, and you’re ready to go! The necessary Bluetooth hardware is already installed, providing seamless integration with the included Python control script.
Comprehensive Control Script: Access the Python control files from our GitHub repository (https://github.com/HPLC-revolution/w515ble-py) to manage pump operations directly from your PC.
Precise Flow Rate Management: Set precise flow rates in µL/min with responsive, real-time control for gradient experiments, enhancing precision for complex liquid handling runs.
Automated Multi-Stage Experimentation: Effortlessly configure custom gradient flow profiles with initial, ramp-up, hold, and ramp-down phases, ideal for intricate liquid handling needs.
User-Friendly Example GUI: Built with Tkinter, the interface displays real-time column pressure and the pump's rate, with easy-to-navigate entry fields for gradient pump control. Python libraries are also provided that allow for customization of the pump's control.

What’s Included:

Waters 515 Pump with Installed Bluetooth Module: Simply connect the pump and begin controlling it via the Python interface.
Access to Control Script & Documentation: Available on GitHub, providing step-by-step guidance for users with basic Python knowledge (https://github.com/HPLC-revolution/w515ble-py). Review the README.md file for additional details.
Laptop in video is NOT INCLUDED

This customized system brings programmable precision, convenience, and enhanced control to a Waters 515 pump. A basic understanding of Python is recommended for accessing and utilizing the control files but not required.

Note: Listing includes the Waters 515 pump and pre-installed Bluetooth hardware. Python control scripts, detailed documentation and follow up support are available through GitHub (https://github.com/HPLC-revolution/w515ble-py). From GitHub, additional programming requests can be made and collaborative user upgrades shared.
