VWR® Advanced magnetic hotplate stirrers are designed to deliver accurate and repeatable results in all research, academic and industrial applications. With temperature ranges up to 500 °C, and stirring speeds reaching 1600 rpm, VWR® magnetic hotplate stirrers provide proper mixing and superior temperature control. Available in three sizes and a choice of two top plate materials.
- Excellent temperature uniformity and powerful stirring
- Easy to read, large LCD displays temperatures and speed
- Industry-leading safety features
- Cool touch and chemical resistant housing
- 5 year warranty
These microprocessor-controlled units feature a front facing control panel with an easy to read LCD that displays temperature settings, speed settings and intuitive icons.
Magnetic hot plate stirrers are available with ceramic or aluminium top plate material. Reflective, white ceramic tops are chemical resistant and easy to clean. Durable aluminium tops will not crack or chip and offer a more even heating surface. A built-in memory recall provides users with the last set temperature, even after the unit has been turned off. For additional safety, a large, hot symbol warning light is illuminated when the hot plate is in use, this remains lit until the top plate is below 40 °C. Units are equipped with redundant safety controls, which will shut down the unit in case of heater malfunction.
Enhanced electronics regulate the robust heater, which brings samples to the desired temperature quickly and efficiently. The low profile design utilises minimal bench space and allows use within a fume hood. Unit housing is constructed of a heat and chemical resistant polymer that remains cool to the touch during operation. The spill resistant design channels fluids away from internal components in the event of a spill.
Corresponding hotplates (heating only 442-1269) or magnetic stirrers (stirring only 442-1310) are also available.
