7” inch hotplate magnetic Stirrers are suitable for various heating and mixing applications with excellent chemical resistance, compact shape and efficient heat transfer. They are widely used in every field of science like biology, chemistry, physical science, pharmaceutical science etc.

Tips:
1 Please heat without connecting probe if the accurate temperature control of the liquid is not required ,without probe the hotplate will heat at large power, but when connecting the probe, the hotplate will reduce the power for accurate temperature control
2 There are some ways to speed up the heating time when connecting the probe, these ways are used by a lot of laboratory
a. Put a lid on the beaker.
b. Wrap the beaker with some heat insulation cotton
