Electronic overhead stirrers, VOS 40 digital and VOS 60 control

Supplier: VWR Collection
Laboratory stirrers which 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 - 2000 min-1.

  • Digital speed display
  • Infinitely adjustable speed
  • Push-through agitator shafts
  • Overload protection and 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 speed and preset speed are constantly monitored and variations are 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 a USB interface to control and document all parameters. An integrated torque trend display enables measurement of viscosity changes.

Programmable functions
Integrated temperature measurement
Interval operation, timer and lock function
Adjustable safety circuit

IP protection class according to DIN EN 60529: IP 40
