Description

Benchmark Scientific overhead stirrers feature high torque and advanced digital microprocessor control for smooth mixing of low- and medium-viscosity samples. Speed and run time are accurately set and monitored on the LCD screen, and the DC brushless motor runs compact and quiet from 30 to 2,200 rpm.

A feed-through keyless chuck holds accessory shafts (0.5–10 mm) firmly in place and is easily tightened and loosened without tools. The stirrer is protected from damage by sensors that shut down operation in the case of high viscosity or obstruction, while a splash cover protects the connection mechanism from potential corrosion. Unlike most mixers, the Benchmark series is supplied with a support stand and mounting hardware; the stirrer attaches easily and securely to the stand for use with a variety of vessels up to 24 inches high.

Features:

  • 40L mixing capacity (H₂O), up to 50,000 mPas viscosity
  • Maximum torque 60 Ncm
  • Digital speed control 30–2,200 rpm with LCD display of speed and time
  • DC brushless motor — compact and quiet
  • Keyless feed-through chuck, 0.5–10 mm shafts
  • Overload/obstruction shut-off sensors and splash cover
  • Supplied with support stand, mounting hardware and 4-arm stainless propeller
  • Universal 100–240 VAC input; 2-year warranty

Includes: stand assembly, 4-arm stainless steel propeller (IPS2050-P-S4) and keyless chuck with protective cover. Optional stainless steel and PTFE (Teflon) propellers are available separately.

Also available: OS20L Overhead Stirrer, 20L (IPS2050-20).
