Secure and Reliable Sample StorageDesigned with five adjustable stainless steel shelves, multiple individual inner doors, and a robust keylock system with a double sealing gasket, this freezer minimizes temperature fluctuations and unauthorized access. High-density polyurethane foam insulation and a low-noise, heavy-duty compressor further enhance reliability for long-term biological sample preservation.
Ease of Use and MaintenanceMobility is facilitated by heavy-duty castor wheels, making relocation within the laboratory simple. The freezer also offers a USB data logger for convenient temperature data export, aiding in documentation and compliance with laboratory standards. Powder coated mild steel and stainless steel construction ensures both durability and ease of cleaning.
FAQ's of Ultra Low Temperature Deep Freezer:
Q: How does the cascade refrigeration system benefit ultra low temperature storage?
A: The cascade refrigeration system uses two independent cooling cycles with environmentally friendly refrigerants to efficiently achieve and maintain ultra low temperatures between -40C and -86C. This system ensures rapid cooling, stable operation, and reliable protection for sensitive biological materials.
Q: What safety features are included to protect valuable samples?
A: The freezer is equipped with an advanced alarm system that provides both audio and visual alerts for high/low temperature, power failure, and door ajar situations. A keylock mechanism with a double sealing gasket and multiple inner doors further protect against unauthorized access and minimize temperature fluctuations.
Q: When should the USB data logger be used?
A: The USB data logger should be used whenever temperature monitoring records are needed, such as for audits, compliance, or research documentation. Users can easily export temperature data for review, backup, or reporting by inserting a USB drive into the interface.
Q: Where can the Ultra Low Temperature Deep Freezer be installed?
A: This freezer is suitable for use in laboratories, hospitals, medical research institutes, blood banks, and pharmaceutical facilities. Its large size and heavy-duty castor wheels make it adaptable for various environments where secure and stable ultra low temperature storage is required.
Q: What is the process for cleaning and maintaining the freezer?
A: Regular maintenance includes checking door seals, cleaning the powder coated mild steel exterior and stainless steel interior, and ensuring that fans and condenser coils are free from dust. Users should periodically download and review data logs and verify alarm functionality to ensure operational integrity.
Q: How does the adjustable shelving and multiple inner doors improve usability?
A: The five adjustable stainless steel shelves allow flexible storage configurations for various sample sizes. Multiple individual inner doors reduce exposure to the main chamber when accessing samples, promoting more consistent internal temperatures and reducing energy consumption.
