Introduction

A rapid low temperature cooling circulating bath is a laboratory instrument that rapidly cools a liquid and circulates it at a controlled low temperature, providing a precise, low-temperature heat transfer fluid for cooling samples and external equipment, and it is used in chemistry, biology, physics, and materials science laboratories. The instrument consists of a bath tank filled with a heat transfer liquid, such as water, glycol, or silicone oil, a powerful refrigeration system that cools the liquid rapidly to low temperatures, a temperature controller, and a pump that circulates the cooled liquid within the bath and through external tubing to external equipment; the rapid cooling capability allows the instrument to reach low temperatures quickly, and the precise temperature control maintains the set temperature with high accuracy, with the operating range depending on the liquid and the refrigeration capacity, from ambient down to low temperatures, such as -40 degrees Celsius or lower. Rapid low temperature cooling circulating baths are used for cooling samples and reactions, for condensing solvents in rotary evaporation, for temperature control of external instruments, such as viscometers, refractometers, and spectrophotometers, for cooling in materials testing, for maintaining samples at low temperatures, for calibrating temperature sensors, and for many other applications that require controlled low-temperature circulation, in research, pharmaceutical, food, and testing laboratories. Features include rapid cooling, precise temperature control, high circulation rate, digital displays, and overtemperature protection. With their rapid cooling and precise control, rapid low temperature cooling circulating baths are essential for low-temperature laboratory work.

FAQ

Q1: What testing scenarios is this bath mainly applied to?

A: The rapid low-temperature cooling circulating bath is used in chemistry, pharmaceutical research, material science, biological analysis, food testing and research laboratories to provide fast, precise low-temperature control with fluid circulation for internal and external applications requiring rapid cooling. It supports low-temperature chemical reactions and synthesis, sample cooling and freezing, external equipment temperature control (reactors, spectrometers, viscometers), material testing at low temperatures, biological sample preservation, and general laboratory low-temperature processes. The rapid cooling capability reduces wait time for experiments requiring low temperatures, while the circulation provides uniform temperature throughout the bath and external equipment. It is essential for chemistry, pharmaceutical, material, biological and research laboratories requiring rapid, precise low-temperature control for chemical reactions, sample cooling, external equipment temperature control, material testing and research, where fast cool-down and stable low-temperature circulation are critical for reaction control, sample integrity, measurement accuracy and experimental efficiency in applications requiring below-ambient temperature control with rapid response and reliable circulation for internal or external use.

Q2: What standards does the bath comply with?

A: The rapid low-temperature cooling 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. Specific applications follow their own test methods. The refrigeration system follows applicable environmental regulations for refrigerant use.

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 for this specialized equipment.

Q4: Is this device difficult to operate? Is professional training required?

A: Operation requires basic training in low-temperature 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 low-temperature 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 and heating/cooling performance 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, oil) 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, cooling rate, 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 cooling 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 rapid low-temperature cooling circulating bath provides 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 low 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 (frostbite risk), and verify temperature uniformity at the sample or external application point. The rapid cooling feature should be used per manufacturer guidelines to avoid thermal stress on the refrigeration system. 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.
