164 ultra low temperature chest freezers

Introduction

An ultra-low temperature chest freezer, available in models that reach about -164 degrees Celsius, is a laboratory storage unit that maintains an extremely low temperature in a chest-style cabinet, with the opening at the top, and it is used for the long-term storage of highly sensitive biological materials, such as cells, tissues, and clinical specimens, in research, clinical, and biobank laboratories. The freezer consists of a top-opening, heavily insulated cabinet, a multi-stage cascade refrigeration system with multiple compressors that reach the very low temperature, a lid with a tight seal, and a digital temperature display; it maintains the set temperature, which can be as low as about -164 degrees Celsius, with high stability, and it is designed to minimize temperature fluctuations and to provide reliable long-term operation, with features such as alarms, locks, backup systems, and temperature monitoring, and the extreme low temperature provides the highest level of preservation for sensitive samples. Ultra-low temperature chest freezers are used for storing biological samples and specimens, for biobanking, for storing cells, tissues, and other research materials, for storing vaccines and pharmaceuticals, for preserving clinical samples, and for many other applications requiring very low temperatures, and they are available in various capacities, with features such as precise temperature control, alarm systems, and reliable operation. With their extremely low temperatures, ultra-low temperature chest freezers are essential for the long-term preservation of sensitive biological materials.

FAQ

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

A: The -164 degrees C ultra-low temperature chest freezer is used in biobanks, stem cell banks, clinical laboratories, pharmaceutical storage, biological research and hospitals to provide deep cryogenic storage at -164 degrees C for long-term preservation of precious biological samples including stem cells, embryos, cells, tissues, DNA and other critical materials requiring temperatures approaching liquid nitrogen (-196 degrees C) without the hazards of liquid nitrogen. It supports stem cell and embryo cryopreservation, long-term biobanking of precious samples, clinical specimen storage, pharmaceutical biological product storage, cell line preservation, and research sample archiving. The -164 degrees C temperature provides excellent long-term stability for biological materials, approaching the glass transition temperature of water.

Q2: What standards does the freezer comply with?

A: The -164 degrees C ultra-low temperature chest freezer complies with relevant IEC 61010 laboratory electrical safety standards, applicable ISO and GB/T standards for cryogenic refrigeration equipment, and relevant medical device regulations. Temperature accuracy should be verified with a calibrated reference. Stem cell and embryo storage follows applicable regulatory requirements (e.g., AABB, FACT). Environmental regulations for refrigerants should be followed.

Q3: What is the warranty period for the whole machine and key components?

A: The whole -164 degrees C ultra-low temperature freezer is covered by a 12-month warranty. The cryogenic refrigeration system, cabinet, controller, baskets and housing are covered, while gaskets, filters and fuses are consumables. Damage from improper use or unauthorized repair is excluded. Extended service contracts are standard for this critical storage equipment.

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

A: Operation requires specialized training in cryogenic freezer use, sample handling and emergency procedures. We provide comprehensive training, operation manuals and application support. Proper temperature setting, cryogenic sample handling, monitoring, alarm response, maintenance and emergency procedures are critical for protecting precious samples.

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 every 6-12 months with cryogenic reference. Continuous temperature monitoring and logging. Gasket inspection and cleaning regularly. Condenser and refrigeration system maintenance per schedule. Alarm system tested periodically. Full system maintenance annually by certified technicians.

Q7: Are supporting consumables universal?

A: Gaskets, filters and fuses are available from specialized suppliers. Long-term consumable cost is low, but energy and maintenance costs are high for -164 degrees C freezers. Refrigerant requires certified technician handling.

Q8: Can I customize parameters or supporting accessories?

A: Customization includes capacity, temperature range, basket configuration, alarm features, data logging, remote monitoring, backup systems and accessories. Additional cryo-boxes and racks can be ordered separately. Custom orders extend delivery lead-time.

Q9: Does the purchase include on-site installation and commissioning service?

A: Yes, -164 degrees C ultra-low temperature freezers include on-site installation, commissioning, temperature mapping and operator training by certified cryogenic specialists. Site preparation guidance is provided before delivery.

Q10: What types of samples are compatible with this equipment?

A: The -164 degrees C chest freezer stores precious biological samples including stem cells, embryos, cells, tissues, DNA, RNA and pharmaceuticals requiring deep cryogenic storage at -164 degrees C. Samples should be in appropriate cryovials or cryo-boxes rated for -164 degrees C. The freezer should not be overloaded. Users should maintain proper temperature, monitor continuously with alarms, minimize lid opening time (temperature recovery is slow), use appropriate cryo-containers, implement strict sample inventory management, have emergency power backup (UPS/generator) and a liquid nitrogen backup contingency plan, and for stem cell/embryo storage, follow applicable regulatory requirements (AABB, FACT). The freezer should be placed in a temperature-controlled room with dedicated 3-phase power and proper ventilation. The refrigeration system should be maintained by certified technicians. Samples should be properly sealed to prevent cross-contamination. The freezer should be allowed 48-72 hours to stabilize before storing precious samples. For critical samples, replication in multiple storage units or liquid nitrogen backup is strongly recommended.
