ALab™ DMS5-340M Magnetic Hotplate Stirrer
Product Detail
The ALab™ DMS5-340M is an LCD digital 5-inch timed heating magnetic stirrer with a strong magnetic field for viscous samples. Its Ø135 mm ceramic-coated aluminum plate heats from RT to 340°C, and a brushless DC motor stirs at 50 to 1500 rpm with a maximum stirring volume of 20 L of water.
One LCD shows 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 DMS5-340M connects to a PC over RS232 for remote control.
Three heating modes (A rapid, B standard, C stable), a settable safety temperature, 420°C overheating protection and two independent safety circuits cover heating safety, and a corrosion-resistant all-metal housing provides heat dissipation and fire protection.

Heating modes and safety
| Function | Detail |
|---|---|
| Heating modes | A rapid heating mode, B standard heating mode, C stable heating mode |
| Overheating protection | 420°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 |

Where it fits
Frequently asked questions
What is the heating range?
From RT to 340°C in 1°C increments, with 420°C overheating protection and a settable safety temperature.
How large a volume can it stir?
The maximum stirring volume is 20 L of water, with stirrer bars up to 80 mm long, at 50 to 1500 rpm.
What does the strong magnetic field do?
The DMS5-340M uses selected high-temperature resistant strong magnets, for strong stirring of viscous samples.
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.
What is the protection class?
The protection class is IP42.
