myBath™ CR Circulating Water Baths

• Constant water circulation ensures even temperature distribution
• Digital PID processing for precise temperature control
• Stainless steel chamber and coil
• Ambient +5° to 100°C
• Stainless steel Chamber and Circulating Coil
• Optional gabled cover and stainless steel test tube racks 

Benchmark™ myBath™ CR circulating water baths offer the same accuracy and convenience of the static myBath™ series, but with faster heat ramping and enhanced stability/uniformity. With constant circulation, water temperature is uniform throughout the chamber, eliminating “cold-spots” and allowing for quick recovery following insertion of frozen samples.

The myBath™ CR utilizes digital PID processing control that accurately maintains and adjusts the temperature to the set parameters. Once the desired temperature has been programmed, the instrument begins to heat, while indicating both the set and actual temperatures on the large, digital display.

The chamber and heating coil are constructed of stainless steel, resulting in easy cleaning. Optional accessories are available for securing test-tubes and an optional gabled lid can be purchased to improve efficiency.

Operating features

JULABO Refrigerated & Heating Circulators for heating and cooling are suitable for external temperature tasks and for temperature applications directly in the bath. A model from three different series' with different capacities can be selected. Powerful circulating pump systems and high heating and cooling capacities guarantee short heat-up and cool-down times. The inevitable dust accumulation that occurs in refrigeration systems is solved by means of an easily removed venting grill, which allows for easy cleaning. Depending on the model, the units are equipped with handles or castors for an easy transportation. All models have a drain tap on the front allowing the fluid to be drained easily. The compact assembly of each unit enables a space to be saved in the laboratory.

• Bright LED temperature display, resolution 0.1 °C
• Keypad for setpoint, switches automatically to the actual value
• PID1 temperature control
• Adjustable high temperature cut-out
• Low liquid level protection
• ATC 1-point calibration
• Timer function
