The OHAUS Incubating Microplate Shakers are optimized for shaking microplates, deep-well plates, or micro-tubes.


  • Microprocessor Control: The variable speed microprocessor control provides consistent uniform shaking action. Microprocessor will display last set-point and will restart if power is interrupted.
  • PID Temperature Controller: Maintains precise temperature control from ambient +5°C to 65°C. Easy-to-use controls allow users to adjust temperature in 1°C increments.
  • Triple Eccentric Drive: Permanently lubricated ball bearings and maintenance free, brushless DC motor provide reliable service and continuous duty operation. 
  • LED Display: Touch pad controls with easy-to-read, independent LED displays for temperature, speed, and time allow operator to view all settings at once. Provides repeatable and accurate results every time and is easily visible across lab benches. Timer will display elapsed time or, when programmed to user defined limit, will shut off unit when time reaches zero. Display will show last used settings, even after power has been turned off.
  • Temperature Calibration Mode: Allows user to calibrate unit to an external temperature device.

Safety Features: Overload Protection: Audible and visual signals will activate when system detects an obstruction or overload of the tray. Speed Ramping Feature: Slowly increases speed to desired set-point to avoid splashing. Audible Alarm: In timed mode, alarm will sound when the time reaches zero. Caution Hot Indicator: Symbol illuminates when the temperature of the air in the chamber reaches 40°C and remains lit until temperature cools down. Spill-Resistant Design: Channels fluids away from internal components.

Available with a clear or opaque polycarbonate Lid:

  • Clear lid permits viewing of samples without disturbing internal temperature. ISLDMPHDG
  • Opaque lid prohibits light exposure to light sensitive samples. 

Operating Conditions: Unit can be run in conditions from 5 to 40°C (41 to 104°F), maximum 80% relative humidity, non-condensing.

Applications: Immunoassays and hybridizations.

Can the Ohaus Incubating Microplate Shaker unit shake without heating, and heat without shaking?

Yes, the Ohaus Incubating Microplate Shaker has been designed for the temperature, speed and time functions to all work independently of one another. You can use it to only heat, only shake, or simply as a timer, or you can use any combination of the functions.


What is the maximum plate height which can be accommodated in the Incubating Microplate Shaker?

The microplate shaker has been tested with both standard and deep-well microplates. Deep-well microplates are commonly approximately 45 mm in height, so we would not recommend using plates which are taller than ~50 mm / 2 inches as they have not been tested with this instrument.

If you are looking to use a particular type of plate which is larger than that, please let contact us at support@orbitalshakers.net and we may be able to arrange testing.


Does this microplate shaker have a slow start to prevent spills?

Yes, the shaker will ramp up the speed slowly to help prevent the contents of the microplate from spilling or splashing. That occurs by default; it is not a setting which you need to turn on.
