Advanced general purpose circulating water baths offer a combination of contemporary cabinet design, advanced microprocessor control and a range of accessories to suit your specific laboratory or process application. High-strength cabinet construction with 304 stainless steel interior tanks withstand the most critical applications in demanding laboratory environments.

Circulating models are available in heated only versions, temperature range 5°C above ambient to +100°C, or combined heated/refrigerated models for operation from 0° C to +100°C.
 

Features
  • Choose from four popular cabinet sizes
  • 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 with RTD probe provides simple, accurate and repeatable temperature control while optimizing control parameters during operation
  • Single stage, centrifugal pump with independent supply/return ports for maximum circulation
  • Reversible stainless steel rack allows for optional reduction of working depth by 2" (50mm) Built to UL and CUL criteria for safety and performance
  • Includes 10’ power cord with plug

 

Microprocessor controller
  • Digital temperature display, simultaneously shows setpoint and actual water temperature
  • Recessed control module protects against dirt and moisture
  • RS-485 communications 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

 

Cabinet and tank construction
  • Integrated industrial strength pump for internal circulation maintains precise temperature uniformity throughout the liquid medium
  • Rounded corners for better water circulation, improved uniformity and easier cleaning; includes a built-in drain with on/off valve
  • Moisture-proof blanketed fiberglass insulation surrounding water chamber improves temperature stability and energy efficiency
  • 304 stainless steel construction resists chemicals, simplifies cleaning
  • Long-life heating elements for quick response to controller
  • Protective non-skid rubber feet protect the lab bench
  • Attractive front panel bezel for easy cleaning
  • Mounting clip for immersion glass thermometer; thermometer sold separately

 

Refrigerated model
  • Refrigeration system allows accurate control at temperatures near or below ambient conditions
  • Quiet-running, hermetically sealed refrigeration system
  • High volume heat removal capacity rated at 3000 BTU/Hr at 27°C (nominal)
  • Ideal for use with 60%/40% ethylene glycol/water mixture to prevent icing at temperatures below 10°C
  • Independent ON/OFF switch for refrigeration system; system can be switched OFF for operation above ambient temperatures

 

Cover
Gable Covers
Gable covers prevent cross-contamination by diverting condensation to the sides for return to the bath medium. Semi-transparent polycarbonate construction permits viewing during operation. Cover may be attached to the side of the bath allowing condensation to flow back into the medium, reducing moisture loss and water accumulation on the lab bench. Cover includes handle. Gable covers recommended for efficient operation above +60°C. Stainless steel cover recommended for temperatures above 75°C.
Concentric Ring Covers
Ring covers are useful for steaming. Covers minimize heat loss, improve temperature uniformity. Concentric ring covers minimize heat loss while stabilizing labware.
Stainless steel flat covers
Used to protect the bath medium when not in use. Flat covers minimize heat loss and maintain bath temperature unitl ready for next application. Covers include handles.
