Introduction
An ultra-low temperature chest freezer is a freezer with a chest design, used for the storage of the samples at the ultra-low temperatures, down to about minus 86 degrees Celsius, and it is used in the laboratories, the biobanks, the hospitals, and the research institutions for the long-term storage of the biological samples. The ultra-low temperature chest freezer consists of an insulated chest with the top-opening lid, a cascade refrigeration system, a temperature control system, a temperature monitoring and an alarm system, and the storage racks or the baskets, and it maintains the ultra-low temperature in the chest, with the chest design providing the efficient insulation and the large storage capacity, with features such as the digital temperature control, the temperature alarms, and the lock; the ultra-low temperature chest freezer is used for the storage of the cells, the tissues, the DNA and the RNA, the proteins, the sera, and the other biological samples, for the long-term preservation, for the storage of the samples for the research and the diagnostics, and for many other applications, and it is available in various capacities; the ultra-low temperature chest freezer is an essential equipment for the cryogenic storage. Ultra-low temperature chest freezers are used in the laboratories, in the biobanks, in the hospitals, in the research institutions, and for many other applications. With their ultra-low temperatures, ultra-low temperature chest freezers are essential for the long-term sample storage.

FAQ
Q1: What testing scenarios is this freezer mainly applied to?
A: The minus 86 degree chest ultra-low freezer is used in research laboratories, biobanks, clinical facilities and pharmaceutical storage for long-term preservation of biological samples including DNA, RNA, proteins, cell lines, tissue specimens, clinical samples and temperature-sensitive reagents. It supports sample archiving for research, clinical trial specimen retention, biobank storage and reagent preservation where ultra-low temperature is required to maintain molecular integrity and biological activity over extended periods. The chest design provides excellent temperature stability and is ideal for high-density, infrequently accessed storage.
Q2: What standards does the freezer comply with?
A: The freezer is designed with reference to IEC 61010 laboratory electrical safety standards and relevant GB standards for ultra-low temperature medical and laboratory equipment. Biobank and clinical applications may reference ISO 9001 quality management and GDP guidelines for temperature monitoring, alarm and backup power requirements.
Q3: What is the warranty period for the whole machine and key components?
A: The whole freezer is covered by a 12-month warranty. The compressors typically carry an extended warranty as specified. The controller, sensors and fans are covered, while gaskets and filters are consumables excluded from warranty. Extended service contracts are recommended for this critical storage equipment.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation is simple: set the target temperature and allow stabilization before loading. No professional training is required, but users should understand the importance of minimizing lid open time, proper sample organization and emergency procedures for temperature excursions. We provide an operation manual and remote guidance.
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 calibrated reference thermometer is recommended every 6-12 months, and more frequently for biobank or clinical storage. Temperature mapping at installation and after relocation is essential. Compressor performance and condenser cleaning should be performed quarterly to prevent failure.
Q7: Are supporting consumables universal? What about the long-term procurement cost?
A: There are no recurring consumables. Gaskets and filters are standard accessories. Long-term ownership cost is significant due to high electricity consumption for ultra-low cooling. Backup power, alarm systems and regular maintenance are strongly recommended to protect stored samples.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes capacity, temperature range, rack configuration and alarm options. Additional racks, sample boxes and temperature monitoring systems 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 freezer with an operation manual. Professional placement and power connection are recommended due to the weight and power requirements. On-site commissioning and training can be arranged for critical storage installations.
Q10: What types of samples are compatible with this equipment?
A: The freezer stores biological and chemical samples stable at minus 86 degrees Celsius within the capacity. Explosive, flammable or highly corrosive materials should not be stored. Users should ensure proper container sealing and use appropriate cryovials or storage boxes. Samples requiring liquid nitrogen temperature should use dedicated cryogenic storage systems.
