 SELLING POINT   
4/6 channels with independently control of start/stop, temperature,speed and display for better parallel experiment control.
Ceramic coating aluminum work plate with fast heat transmission and strong resistance to corrosion.
Powerful, rapid heating with accurate PlD temperature control
Spark-free DC brushless motor with extended life and no maintenance
Compatible with various heating block or reaction vessels for a varietyof application scenario
Ultra space-saving with 4/6 channel integrated in one instrument
“HOT" warning flashes on the LCD display if the work plate temperature  is above 50°C after the user turn off the power switch.
Two independent safety circuits keep monitoring the instrument. When overheating  is detected and the sensor malfunctions, it will stop heating and sound alarm;
 When short circuit is detected, it will cut off the power to ensure the human safety.
Reliable safety mechanism, compliant to lEC61010-1\UL61010-1\BSEN61010-1\CAN\CSA-C22.2NO.61010-1 and all other safety regulations of laboratory heating devices, competent with tasks without human surveillance.
Anplications
The 4/6 channel hotplate magnetic stirrers are designed for parallel experiment and multiple paramete optimization, thus can serve as handy tools for Kjeldahl nitrogen determination, Soxhlet extraction and parallel synthesis, etc. They are ideal choices for test laboratories in food, animal feed, textile, soil, sewage, water treatment, pharmaceutical, polymerization, petroleum products, resin and plastic sectors. The user can handle 4 or 6 tests at the same  time with stable performance, good reproducibility,high accuracy and easy operation.
The design of 4/6 channel hotplate magnetic stirrers aim to turn your laboratory into a space-saving, safe, highly efficient, tidy and neat benchmark among peers. They are well recognized by higher education, pharmaceutic manufacturer, biotech company, research institute and food manufacturer as an eco-friendly magnetic stirrer for synthesis.
