DMS7-550M LCD Hot Stirrer, 7”

Description

The DMS7-550M is an advanced thermal stirrer with an extra large work surface (7 inches) and a reinforced magnetic field
for reliable stirring even of viscous liquids and larger volumes. It is designed for research and
analytical laboratories that require stable temperature control, high safety and long-term operation.

✅ **Large work surface – 7” glass-ceramic plate** with high chemical resistance and easy cleaning
✅ **Strong magnetic field** – ensures stable stirring of even viscous samples and reactions
✅ **LCD display** – clear display of speed, time and temperature (set/actual values)
✅ **Three heating modes** – Rapid, Standard and Stable heating mode for different needs
✅ **Advanced safety** – dual protection circuits, HOT warning, overheating protection and safety lock
✅ **Quiet & long life** – brushless DC motor, spark-free, maintenance-free and with low noise level
✅ **Timer** – adjustable 1 minute up to 99 hours 59 minutes
