FAQ
What is the Controlled-Rate Freezer mainly used for?
The Controlled-Rate 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.
What standards does the Controlled-Rate Freezer comply with?
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?
We provide a 12-month limited warranty on the instrument and its key working parts. Consumables, accessories and parts subject to normal wear are excluded, as is damage caused by incorrect operation or maintenance. An extended service plan is available on request.
Is the Controlled-Rate Freezer difficult to operate?
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.
How often should the Controlled-Rate Freezer be calibrated?
Factory calibration is included, and routine verification is recommended every 6 to 12 months using suitable reference materials. Regulated sites may require more frequent checks and documented records. Calibration support and certificates can be provided on request.
Are consumables and spare parts easy to obtain?
The instrument uses standard, widely available consumables rather than special locked items. Replacement parts, accessories and consumables can be ordered from us against the model number. We keep common service parts in stock for prompt supply.
Can the Controlled-Rate Freezer be customised?
Yes, common options include different ranges, voltages, accessories, interfaces and capacity or size configurations. We confirm feasibility, specifications and any delivery impact before order confirmation. Custom requirements are reviewed case by case.
Do you provide on-site installation?
The unit is delivered ready for set-up, with clear commissioning steps in the manual. We provide remote technical support during installation. For larger or regulated systems, a factory-trained engineer can attend on site on request.
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.
