Introduction
A refrigerated circulating bath is a laboratory instrument that combines a temperature-controlled liquid bath with a refrigeration system and a circulating pump, providing precise temperature control of a heat transfer liquid both above and below ambient temperature, and it is used for cooling, heating, and temperature control of samples and external equipment in laboratories and industry. The instrument consists of an insulated bath tank filled with a heat transfer liquid, such as water, glycol, or silicone oil, a heating element, a refrigeration system, a temperature controller, and a pump that circulates the liquid within the bath and through external tubing; the combination of heating and cooling allows the instrument to maintain temperatures over a wide range, from below freezing to above ambient, with high accuracy and stability, and the circulation ensures uniform temperature throughout the bath and in the external circuit. Refrigerated circulating baths are used for maintaining samples at constant temperatures, for cooling reactions and condensers, for temperature control of external instruments, such as viscometers, refractometers, and spectrophotometers, for calibration of temperature sensors, for viscosity and density measurements, for materials testing, for incubation at below-ambient temperatures, and for many other applications, in chemistry, biology, pharmaceutical, food, materials, and testing laboratories, and in industrial processes. Features include precise temperature control over a wide range, high circulation rate, digital displays, and alarms. With their versatile temperature control, refrigerated circulating baths are essential for temperature-controlled work in laboratories and industry.

FAQ
Q1: What testing scenarios is this bath mainly applied to?
A: The refrigerated circulating bath is used in chemistry, biological research, pharmaceutical testing, material science, food analysis, environmental and quality control laboratories to provide precise below-ambient temperature control with fluid circulation for internal and external applications. It supports low-temperature chemical reactions and synthesis, sample cooling and incubation, external equipment temperature control (jacketed reactors, viscometers, analytical instruments), material testing at controlled low temperatures, biological sample preservation, and general laboratory temperature-controlled processes. The refrigeration provides below-ambient temperatures, while the circulation ensures uniform temperature throughout the bath and connected external equipment. It is essential for chemistry, biological, pharmaceutical, material and research laboratories requiring reliable below-ambient temperature control for chemical reactions, sample cooling, external equipment temperature control, material testing, biological sample preservation and quality control, where precise refrigerated temperature with circulation is critical for reaction control, sample stability, measurement accuracy and experimental reproducibility in applications requiring below-ambient temperature control with reliable circulation for internal or external use in laboratory and research environments.
Q2: What standards does the bath comply with?
A: The refrigerated circulating bath complies with relevant IEC 61010 laboratory electrical safety standards and applicable GB/T standards for laboratory temperature control equipment. Temperature accuracy should be verified with a calibrated reference thermometer for critical applications. The refrigeration system follows applicable environmental regulations for refrigerant use. Specific applications follow their own test methods.
Q3: What is the warranty period for the whole machine and key components?
A: The whole bath is covered by a 12-month warranty. The refrigeration system, pump, controller and tank are covered, while bath fluid, gaskets and fuses are consumables or accessories. Damage from improper fluid use, overheating or unauthorized repair is excluded. Extended service contracts are available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in refrigerated bath operation, fluid selection and refrigeration safety. We provide an operation manual and remote guidance. Proper fluid selection, level maintenance, temperature setting, external connection and safety procedures are important for reliable operation.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Temperature calibration against a reference thermometer recommended every 6-12 months for critical applications. Refrigeration system performance checked periodically. Pump flow verified. Gasket and seal inspection regularly. Bath fluid quality and level checked regularly. Full system maintenance annually.
Q7: Are supporting consumables universal?
A: Bath fluid (water, glycol, alcohol) is available from chemical suppliers, though type should match the temperature range. Long-term consumable cost is low to moderate depending on usage and fluid type.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes temperature range, bath capacity, pump flow, controller type and external circulation features. Additional tubing, probes and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the refrigerated bath and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged for laboratory setup. Remote guidance is provided.
Q10: What types of applications are compatible with this equipment?
A: The refrigerated circulating bath provides below-ambient temperature control for compatible laboratory applications within the temperature range, cooling capacity and pump specification. Highly corrosive fluids should not be used in the bath without proper lining. External connections should use compatible tubing rated for low temperatures. Users should select appropriate bath fluid based on the required temperature (water/glycol for moderate low temps, special fluids for very low temps), ensure proper fluid level, avoid operating the pump without fluid, follow safe handling procedures for low-temperature fluids, and verify temperature uniformity at the sample or external application point. The bath should be placed in a well-ventilated area with proper clearance for condenser airflow, and not operated continuously at extreme low temperatures for extended periods to prolong compressor life. Routine condenser coil cleaning is recommended for efficient refrigeration performance.
