Stirrers

Stirrers are used ubiquitously in laboratories for simple mixing procedures with solutions of varying viscosities and heating needs. Hotplate varieties bring solutions up to heat quickly and efficiently, and powerful magnets in automatic stirrers deliver reliably consistent performance for all samples. Stirring rods and powered stirring units are all built of durable materials and deliver long-lasting performance under regular or continuous use. Surfaces are easy to clean for low maintenance concerns.

VWR® VMS Advanced Magnetic Hotplate Stirrers

Supplier: VWR Collection

Compact stirrers with a ceramic glass plate provide excellent chemical resistance. Units feature digital error code display, a 'hot' top indicator to warn users that surface is hot, a fixed safety circuit that shuts off the heater if temperature rises above 550 °C, and three operating modes to choose from (standard, safe and adjustment protection). Stirrers have a speed display scale and optional capability to connect directly to a PT1000 temperature sensor; when using this functionality, control accuracy in the medium is ±0,5 °C.
