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.
