Laboratory stirrers that are ideal for simple stirring tasks, suitable for quantities up to 25 L (VOS 40 digital), or for intensive stirring tasks for quantities up to 40 L (VOS 60 control). Due to microprocessor-controlled technology, the stirrers automatically adjust the speed within the speed range of 0/30 to 2000 min⁻¹.

• Digital speed display
• Infinitely adjustable speed
• Push-through agitator shafts
• Overload protection - units can be operated for short periods in overload conditions
• Error code display

Safety circuits ensure automatic cut-off in anti-stall or overload conditions. The actual shaft and pre-set speed are constantly monitored, and variations adjusted automatically. This guarantees a constant speed even with changes in sample viscosities. Stirrers have a slim casing and provide quiet operation.

The VOS 60 control model features a removable wireless controller and a digital, multilingual TFT display. This stirrer is equipped with a RS232 and USB interface to control and document all parameters. An integrated torque-trend display enables measurement of viscosity changes.
