Shaking Circulating Water Baths

By Thermo
Shaking Circulating Water Baths

Two baths in one, Lindberg/Blue M shaking water baths are designed to meet industrial research, environmental, biotech, and general laboratory applications that require close temperature control with a reciprocating motion. The multi-use design allows operation with or without the shaker function. Choose from heated only or heated and refrigerated models.

  • Temperature range from 5°C above ambient to +100°C, uniformity ±0.1°C; refrigerated model rated at 0°C to +100°C, ±0.1°C
  • Microprocessor control with RTD probe for simple, accurate and repeatable operation
  • Single stage, centrifugal pump with independent supply/return ports for maximum circulation
  • Independent, adjustable shaker function with separate ON/OFF switches
  • Includes 10' power cord with plug
  • Microprocessor Controller
  • Digital temperature display, simultaneously reads setpoint and water temperature
  • Recessed control module protects against dirt and moisture
  • RS-485 communication port is available as an option
  • Dual Independent Overtemperature Safety System

Adjustable high limit control prevents critical process overtemp conditions at any point over the bath operating range, protecting the bath and its load; interrupts heat, flashes visual warning and automatically resets when temperature returns to normal. Fixed overtemperature safety, factory set 105°C, shuts off bath power; push button manual reset.

Shaker Control

  • Independent ON/OFF switch for shaker operation
  • Reciprocating action, adjustable over a range up to 200 strokes per minute
  • Speed control dial with illuminated power switch for variable motion adjustment
  • Adjustable stroke from 0.875" to 1.5"

Rounded corners for better water circulation, improved uniformity and easier cleaning; includes a built-in drain. Independent shaker carriage, welded 304 stainless steel on high impact nylon rollers; removable Insulated chamber walls improve temperature stability and energy efficiency. Protective non-skid rubber feet to protect the lab bench. Mounting clip for immersion glass thermometer; thermometer sold separately. Long-life, low watt density heating elements for quick response to controller.

Non-Refrigerated Shaking Circulating Water Bath (UL and CUL Approval Pending)

Temperature Range: 5°C above ambient to +100°C, uniformity ±0.1°C; maximum temperature dependent on altitude. A gable cover is recommended for most efficient operations Above 60°C.
