FAQ

What is the Liquid Nitrogen Freezer mainly used for?

The Liquid Nitrogen Freezer is used for medium- to long-term storage of samples, reagents, biological materials and specimens at sub-zero temperatures. It serves clinical, diagnostic, research and industrial laboratories that need stable freezing without reaching ultra-low temperature levels.

Which standards and regulations apply to the Liquid Nitrogen Freezer?

The unit is designed with reference to IEC 61010 electrical safety requirements and relevant GB/T standards for laboratory freezers. Storage of biological materials should follow applicable laboratory and biobanking guidance. Compliance documentation can be provided on request.

How long is the warranty period?

A 12-month warranty applies to the complete equipment against defects in materials and workmanship. It excludes consumables, wearing components and accidental or misuse damage. Our service team handles claims against the serial number, and longer cover can be arranged.

Will staff need special training?

Day-to-day use is simple, with clear prompts and pre-set functions reducing manual steps. New operators should review the manual and complete a short familiarisation. Our technical team offers remote support during the first runs.

How long does delivery usually take?

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.

Is calibration included?

The unit is calibrated and tested before delivery. For ongoing accuracy, verify it against traceable reference standards every 6 to 12 months, or according to the laboratory quality schedule. We can arrange calibration service and certificates where required.

Where do we get replacement parts?

Filters, seals, probes and similar items are standard and can be supplied through our channel. Customers may also source equivalent items that meet the specification. Provide the model and serial number to confirm compatibility before ordering.

Can it be adapted to our requirements?

Customisation is supported for many installations, including tailored parameters, connections and accessories. Our team reviews the requirement and confirms feasibility and lead time in advance. We avoid committing to options that cannot be delivered reliably.

Is installation and commissioning included?

Benchtop and standard units typically require only placement and connection before use, while larger systems may need professional commissioning. We confirm the installation requirements at order stage. On-site service and training can be provided if needed.

What maintenance and safety points matter?

Flammable materials, pressurised containers and samples needing ultra-low temperatures should not be stored in this unit. Use low-temperature-rated containers, avoid overloading and keep vents clear. Follow laboratory safety regulations.
