Four E’s Scientific MS321-2 Hub Controller For Magnetic Hotplate Stirrer and Charging Stand
The Four E’s Scientific MS321-2 is a 7-inch touchscreen hub controller designed to independently manage multiple MS321-1 magnetic hotplate stirrer units from a single interface. Rather than setting up and monitoring several individual stirrers separately, the MS321-2 lets one operator control temperature, speed, and run time for up to 6 wired units — and an unlimited number of wireless units — from one touchscreen.
This is a controller and charging stand only; it requires one or more MS321-1 magnetic hotplate stirrer units to form a working system. It is sold separately for laboratories that already own MS321-1 units and need an additional or replacement controller, or as part of the complete MS321 Multi-Stirrer Hub System Bundle.
Key Features
7-Inch High-Resolution Touchscreen
A 7-inch LCD touchscreen provides a clear overview of every connected stirrer’s status, with independent control of temperature, speed, and run time for each unit.
Manages Up to 6 Wired + Unlimited Wireless Units
The hub supports up to 6 stirrers via 2-metre wired connections plus an unlimited number of wireless connections, giving flexibility to scale a stirring setup as a laboratory’s needs grow.
Bluetooth, 2.4G Wireless, and Wired USB Connectivity
Multiple connectivity options — Bluetooth, 2.4G wireless, and wired USB — support real-time data transmission and control across different laboratory layouts and distances (up to 10m wireless range).
Long-Life Rechargeable Battery
A 5000mAh lithium polymer battery provides up to 8 hours of runtime on a single charge, with a 3-hour charging time via the included charging stand, supporting untethered operation around the lab.
Magnetic Charging Stand
The charging stand uses convenient magnetic charging, making it quick and simple to dock the controller between uses.

Applications
The MS321-2 Hub Controller is suited to laboratory settings including:
- Parallel synthesis and method screening — independently monitor multiple reactions from one interface
- High-throughput QC sample preparation — manage several stirring stations without walking between benches
- Teaching laboratories — one instructor console overseeing several student stirring stations
- Scaling an existing stirrer fleet — adding a second controller as a stirring setup grows
