ALab™ DMS4-550 Magnetic Hotplate Stirrer
Product Detail
The ALab™ DMS4-550 is an LCD digital 4-inch timed heating magnetic stirrer. Its 100 × 100 mm glass-ceramic plate heats from RT to 550°C, and a brushless DC motor stirs at 50 to 1500 rpm with a maximum stirring volume of 10 L of water.
The LCD shows the set and actual values of speed, time and temperature. A PT1000 external temperature sensor (accuracy ±0.2°C) measures the liquid, the timer runs 1 min to 99 h 59 min, and the DMS4-550 connects to a PC over RS232 for remote control.
Three heating modes (A rapid, B standard, C stable), a settable safety temperature, 580°C overheating protection and two independent safety circuits cover heating safety. The corrosion-resistant all-metal housing provides heat dissipation and fire protection, and a waterproof edge design keeps spills out of the electronics.

Heating modes and safety
| Function | Detail |
|---|---|
| Heating modes | A rapid heating mode, B standard heating mode, C stable heating mode |
| Overheating protection | 580°C |
| Safety temperature | Can be set |
| Two independent safety circuits | Continuously monitor the unit; on overheating or a sensor fault the stirrer reports an error and stops heating; on a short circuit the power supply is cut off automatically |
| Residual heat warning | When the plate is above 50°C with heating off, "HOT" flashes on the screen, also after the power is switched off |
| Safety lock | Prevents accidental change of the operating settings |
| Buzzer | Sounds on a malfunction and at the end of the timer countdown |
| Timer end | Heating stops at the end of the countdown while stirring continues |
| Waterproof edge | The plate edge design keeps spilled liquid out of the unit and away from the electronics |

Where it fits
Frequently asked questions
What is the heating range?
From RT to 550°C in 1°C increments, with 580°C overheating protection and a settable safety temperature.
How large a volume can it stir?
The maximum stirring volume is 10 L of water, with stirrer bars up to 40 mm long, at 50 to 1500 rpm.
What is the plate made of?
Glass ceramic (100 × 100 mm (4 inch)), resistant to strong acids, alkalis and high temperature, and easy to clean.
What are the heating modes?
A rapid heating mode, B standard heating mode and C stable heating mode, to suit different heating needs.
What happens when the timer ends?
Heating stops at the end of the countdown while stirring continues, and the buzzer sounds.
How accurate is the liquid temperature control?
With the PT1000 external sensor (accuracy ±0.2°C), the temperature control accuracy of the heating liquid is ±1°C below 100°C and ±1% above 100°C.
