Overview

Talboys Advanced Multi-Position Stirrers are powerful magnetic stirrers with precise speed control that offers repeatable performance. Synchronized operation ensures uniform mixing at each position.

Stirrer is supplied with a 1" (2.5cm) PTFE coated stir bar for each position and can be run in conditions from 5 to 40°C (41 to 104°F), 20% to 80% relative humidity, non-condensing. Stirrer includes a 5 year, industry leading limited warranty on parts and labor.

Features:

  • Synchronized and uniform mixing
  • Low profile design
  • 5 year industry leading warranty
Microprocessor Control Precisely regulates speed through the entire range. Stirring function, with continuous duty motor and magnet, maintains speed, even under changing load or viscosity.
LED Display Touch pad controls with easy-to-read, independent LED displays for speed and time. Speed is adjustable in 10rpm increments. Timer will display elapsed time or, when programmed to user defined limit, will shut off unit when time reaches zero.
Top Plate Material Features a chemical resistant, reflective white top plate surface that is easy to clean.
Large Top Plate Stirs multiple vessels at once with helpful position indicators.
Low Profile Design Takes up minimal space. Spill-resistant housing channels fluids away from internal components. Cast aluminum base offers durability and added stability.
Speed Ramping Feature Slowly increases speed for improved safety and enhanced coupling. Avoids splashing, improves spin bar control and provides excellent low speed control.
Audible Alarm In timed mode, alarm will sound when time reaches zero.
