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.

Magnetic Stirrers with Remote Control, Multi-Position

Supplier: THERMO H + P LABORTECHNIK

Compact magnetic stirrers with VARIOMAG drive, hermetically sealed in resistant stainless steel housing (except MINI units which are plastic), making these stirrers ideal for use directly in water baths. MINI stirrers are ideal for integration in analytical instruments, cuvette holders or photometers due to their size, however these plastic units are not designed for use directly in baths. There are units with up to 60 stirring positions in this range, and a choice of three external control units. The TELEMODUL 7 has one power setting, the TELEMODUL 20 C has four power settings: 25%; 50%; 75% and 100% and can store three programmes, the TELEMODUL 40 C features ten different power settings from 10 to 100% and a RS232 interface.

Electronic overhead stirrers, Hei-TORQUE series

Supplier: Heidolph Instruments GmbH & Co.KG

Powerful electronic stirrers that feature a smooth start operation which prevents spills and splashing media. The speed ramps up slowly until set speed has been reached. Both models feature safe start and stop of operation via an intuitive glass slide touch panel to avoid accidental start-up. An overtemperature sensor shuts off the unit in dangerous heat-up situations, ideal for unattended continuous operation. All units are designed for continuous 24-hour operation, including challenging high viscosity applications in polymer research. High torque levels give better mixing results in less time, maintenance-free motors reduce repairs and down time. Hei-TORQUE Value 400 and Hei-TORQUE Precision 400 units have two speed gears.
