5" Multi Magnetic Hotplate Stirrers
with Hub Control
7" Touchscreen Hub · Bluetooth · 2.4G Wireless · USB · Unlimited Wireless Stirrers · PID Control to 310°C
Every lab with more than two hotplates has the same problem: someone walking between units to read setpoints, adjust speeds, and check that nothing has run away. The MS321 replaces that walk with a 7" touchscreen hub — one controller, one glance, every stirrer in the lab mapped, monitored, and adjustable in real time. Wireless range has no device limit. Temperature holds to ±1°C. The walk is optional now.
Why Centralized Hotplate Control Matters
A standalone hotplate stirrer asks the operator to become the monitoring system — walk over, read the display, verify nothing is drifting, repeat for every unit running a protocol. On benches with three, six, or a dozen stirrers in parallel, that manual check is where reproducibility breaks down: someone misreads a setpoint, misses a temperature excursion, or simply skips the walk when deadlines tighten.
The MS321 Hub Control puts every connected stirrer on one 7-inch LCD touchscreen — set temperature, speed, and run time for each unit individually, watch actuals update live, and catch any deviation before it costs you a run. Wired USB supports up to 6 stirrers; wireless Bluetooth / 2.4G imposes no device limit. One hub can run the whole bench.
Unlimited Wireless
Bluetooth and 2.4G wireless with no device cap — scale from a single stirrer to an entire bench without rebuying the controller. Wired USB path available for up to 6 units.
PID to 310°C
PID controller delivers fast heating with ±1°C accuracy. Configurable safety cutoff from 50°C to 325°C. PT1000 external probe auto-detected when plugged in.
5000 mAh Battery
The controller runs untethered — large-capacity battery supports long working hours, magnetic charging snaps on without wrestling connectors. Carry the hub, not the cord.
Ceramic Plate Surface
Φ5" aluminium alloy plate with ceramic coating — corrosion-resistant against spills, resistant to high temperature, and wipes clean with any lab disinfectant.
"One hub. Every stirrer. One screen." — Each hotplate shows its own tracking number on a dedicated LED display, so mapping physical units to the hub's touchscreen is immediate — no guesswork about which stirrer is "Unit 3."

Ideal Applications
Parallel Synthesis
Run multiple reactions side by side with distinct temperature and speed profiles — monitor all of them from the hub without walking the bench.
Method Development
Screen dissolution, crystallization, and formulation conditions across multiple stirrers simultaneously, with live logging of every setpoint.
Teaching & Core Labs
One instructor, one screen, a whole classroom of stirrers monitored. Ideal for academic labs, shared core facilities, and training environments.
Available Configurations
Order the controller once, then scale the hotplate count to match your bench. Both parts are sold as separate line items — select the combination that fits your workflow.
