Overhead stirrers

$0.00

Overview

The OS40-Pro, OS20-Pro, OS40-S and OS20-S are efficient and carefully controlled digital overhead stirrer models for the safe and effective mixing of large volumes of liquids.

The OS40-Pro LCD and OS20-Pro LCD digital overhead stirrers allow the user to set the required torque and speed, and observe their true values on an easy-to-read LCD display. An accurate microprocessor controls stirring speed and guarantees precision in the speeds achieved.

The OS40-S LED and the OS20-S LED models provide a precise display of the actual speed that is selected via an analog dial.

Both LED and LCD models have over-torque protection to automatically stop motor in case of continuous overload. Anti-spill microprocessor control insures the slow start up of speed to prevent sample spills.

Features of the OS40-Pro, OS20-Pro, OS40-S and OS20-S Overhead Stirrers:

  • High torque
  • A choice of 40L or 20L capacities
  • Through shaft design to allow for adjustment of impeller position
  • Speed 50-2200 rpm
  • Large 0.5 – 13 mm chuck diameter accommodates many shaft types
  • Continuous overload automatically stops motor
  • Slow startup to avoid sample spills
  • Analog speed control, speed displayed on LED display (OS40-S and OS20-S)
  • Microprocessor setup and control of parameters, speed displayed on bright LCD display (OS40-Pro and OS20-Pro)
  • RS232 port for PC control and documentation (OS40-Pro and OS20-Pro)
