VWR® Incubating Orbital Shaker, Model 3500I

980153 980153-C
The microprocessor control of the Model 3500I provides consistent, uniform mixing action.

  • Microprocessor Control with Digital Display for Speed, Temperature, and Time
  • Opti-Flow Forced Ventilation System
  • Triple Eccentric Drive with Brushless Motor
  • Five-Year Warranty
  • NIST-Traceable, ISO/IEC 17025 Accredited Calibration Certificate from Troemner Available
A spill-resistant touchpad adjusts the temperature in 1°C increments

For added safety, a ramping feature increases speed to set point, and a built-in load sensor automatically reduces rpm during unbalanced conditions to further prevent spills and protect samples. The brushless motor is designed to handle heavy load, and the spill-resistant design protects internal components from accidental spills and leaks.

The timer displays elapsed time or counts to zero and shuts off the unit when programmed to user-defined limit. An alarm sounds when time reaches zero. The temperature-calibration mode allows the unit to be calibrated to an external temperature device, and the Opti-Flow forced ventilation system uses twin induction fans and air deflectors to deliver temperature uniformity and stability. The Accu-Drive™ Shaking System ensures precise speed control. This system monitors shaking speed and maintains set point even under changing loads.

Certifications: RoHS certified. TUV Listed. Calibrated Shakers include a Troemner ISO/IEC Accredited Calibration Certificate traceable to NIST. ISO/IEC 17025 certified. Accredited by NVLAP under Laboratory Code 105013-0 to perform ISO/IEC 17025 calibrations.
