Ms-H380-PRO LCD Digital Hotplate Magnetic Stirrer with Ceramic Coated Plate

100mPas, equivalent to viscosity of olive oil (cooking oil), beyond which the mixing volume and speed should reduce accordingly.

The temperature rise of magnetic stirrers is influenced by many factors like: Excessive airflow through the fume hood, Uneven contact area between vessel and hotplate surface, Too large sample volume, Whether the vessel is equipped with thermal insulation, Size of the vessel and other factors would result in too slow temperature rise.

Use a vessel made of stainless steel or aluminum alloy, Use methyl silicone oil with small specific heat value, Cover the vessel in the heating process, Equip the heating vessel such as beaker with thermal insulation layer or other protective measures.

Must add and mix in the heating process, preferably at 600-800RPM, Use water with high specific heat value or low-viscosity methyl silicone oil containing stabilizer.

The jittering results from failure of stirring bars. First check the vessel bottom for flatness. If the vessel bottom is OK, check the stirring bar for compatibility. For round-bottom flasks, users are advised to use olive-shaped stirring bar. Smaller stirring bars are suggested for small vessels. If the reasonably chosen stirring bar still does not work, try to replace the stirring bar in order to confirm whether it is due to the degaussing of the stirring bar. Moreover, excessively high rotati
