Introduction
A low temperature water circulating bath is a water bath with the circulation and the cooling, used for the temperature control of the samples and the processes at the low temperatures, and it is used in the chemistry, the biology, the pharmaceutical, and the many other laboratories. The low temperature water circulating bath consists of an insulated bath, a heating and a refrigeration system, a circulating pump, a temperature control system, and the controls, and it provides the controlled temperature of the water, which can be below the ambient temperature, and it circulates the water to maintain the uniform temperature, with features such as the digital temperature control and the circulation; the low temperature water circulating bath is used for the incubation of the samples at the low temperatures, for the temperature control of the reactions, for the cooling of the instruments, for the calibration, and for many other applications, and it is available in various sizes and temperature ranges; the low temperature water circulating bath provides a stable and a uniform temperature, and it is an essential instrument for the temperature control. Low temperature water circulating baths are used in the chemistry laboratories, in the biology laboratories, in the pharmaceutical industry, in the research, and for many other applications. With their circulation and the cooling, low temperature water circulating baths are essential for the low-temperature incubation.

FAQ
Q1: What testing scenarios is this bath mainly applied to?
A: The low-temperature water circulating bath is used in chemistry, pharmaceutical, biological and analytical laboratories to provide precise below-ambient temperature control for internal and external applications. It supports low-temperature chemical reactions, enzyme assays, sample incubation, rotary evaporation cooling, refractometer and viscometer temperature control, and instrument calibration. The circulating pump allows the bath to be connected to external equipment requiring constant temperature, such as jacketed reactors, condensers and analytical instruments. It is essential for laboratories requiring stable low-temperature conditions for reactions, measurements and equipment cooling where ambient temperature fluctuations would affect results or equipment performance.
Q2: What standards does the bath comply with?
A: The circulating bath is designed with reference to IEC 61010 laboratory electrical safety standards and relevant GB/T standards for laboratory temperature control equipment. Temperature accuracy should be verified with a calibrated reference for critical applications.
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, heater and controller are covered, while bath fluid and filters are consumables. Damage from improper fluid use, overloading or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in temperature control and refrigeration system maintenance. We provide an operation manual and remote guidance. Proper fluid selection, level maintenance and temperature setting 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 is recommended every 6-12 months. Bath fluid should be changed periodically. Refrigeration system maintenance including condenser cleaning follows the manufacturer schedule. Pump flow can be verified periodically.
Q7: Are supporting consumables universal?
A: Bath fluid such as water, ethylene glycol or silicone oil is available from chemical suppliers, though fluid type should match the temperature range. Long-term consumable cost is low to moderate.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes temperature range, bath capacity, pump flow and control 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 bath and accessories with an operation manual. Remote commissioning guidance is provided. On-site service is not included for standard orders.
Q10: What types of applications are compatible with this equipment?
A: The bath provides temperature control for compatible laboratory applications within the temperature range and pump capacity. Highly corrosive fluids should not be used in the bath without proper lining. External connections should use compatible tubing rated for the temperature range. Users should select the appropriate bath fluid based on the required temperature, ensure adequate fluid level, and avoid operating the pump without fluid to prevent damage.
