FAQ
Q1: What testing scenarios is this freezer mainly applied to?
A: The -135 degrees C ultra-low temperature chest freezer is used in biobanks, clinical laboratories, pharmaceutical storage, biological research, hospitals and research institutions to provide cryogenic storage at -135 degrees C for long-term preservation of biological samples including cells, tissues, stem cells, DNA, RNA, proteins and other critical biological materials. It supports long-term biobanking and sample archiving, clinical specimen storage, pharmaceutical biological product storage, cell line and stem cell preservation, research sample storage, and vaccine storage. The -135 degrees C temperature provides excellent long-term stability for biological materials, below the glass transition temperature of amorphous water (-135 degrees C), effectively stopping molecular motion and degradation.
Q2: What standards does the freezer comply with?
A: The -135 degrees C ultra-low temperature chest freezer complies with relevant IEC 61010 laboratory electrical safety standards, applicable ISO and GB/T standards for ultra-low temperature refrigeration equipment, and relevant medical device regulations. Temperature accuracy should be verified with a calibrated reference. Biobanking follows ISBER best practices. Environmental regulations for refrigerants should be followed.
Q3: What is the warranty period for the whole machine and key components?
A: The whole -135 degrees C ultra-low temperature freezer is covered by a 12-month warranty. The ultra-low 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 basic training in ultra-low freezer use and emergency procedures. We provide operation manuals, training and application support. Proper temperature setting, sample handling, monitoring, alarm response and emergency procedures are important for protecting valuable 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. Continuous temperature monitoring for critical storage. Gasket inspection and cleaning regularly. Condenser coil cleaning per schedule. Refrigeration system performance verified annually. Alarm system tested periodically. Full system maintenance annually.
Q7: Are supporting consumables universal?
A: Gaskets, filters and fuses are available from specialized suppliers. Long-term consumable cost is low, but energy costs are higher for ultra-low 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, connectivity and accessories. Additional baskets 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, -135 degrees C ultra-low temperature freezers include on-site installation, commissioning, temperature mapping and operator training by certified specialists.
Q10: What types of samples are compatible with this equipment?
A: The -135 degrees C chest freezer stores biological samples including cells, tissues, stem cells, DNA, RNA, proteins, specimens and pharmaceuticals requiring long-term storage at -135 degrees C. Samples should be in appropriate cryovials or containers rated for -135 degrees C. The freezer should not be overloaded. Users should maintain proper temperature, monitor continuously with alarms, minimize lid opening time, use appropriate cryo-containers, implement sample inventory management, have emergency power backup and a contingency plan, and for biobanking, follow ISBER best practices. The freezer should be placed in a temperature-controlled room with dedicated power and ventilation. The condenser should be cleaned regularly. Samples should be properly sealed. The freezer should be allowed 24-48 hours to stabilize before storing valuable samples. For critical samples, replication in multiple storage units is recommended. The -135 degrees C temperature is below the glass transition temperature of water, providing excellent long-term sample stability without liquid nitrogen.
