Description

The 728L Ultra Low Temperature Freezer YG0323 is designed to provide maximum security for biological samples, ensuring stable long-term storage at temperatures ranging from -40°C to -86°C. Equipped with a dual refrigeration system, this freezer can operate independently to maintain -80°C even in case of failure, making it ideal for blood banks, hospitals, research institutes, and laboratories in the electronic and chemical industries.

With an advanced LCD touch screen display, users can easily control, monitor, and log temperature changes, access alarm records, and manage settings efficiently. The dual cascade refrigeration system, using fluorine-free eco-friendly refrigerants, ensures 50% energy savings, while the VIPIIPLUS second-generation vacuum insulation board technology provides superior thermal insulation and structural stability. Additionally, the detachable inner door makes defrosting and cleaning easier, reducing maintenance time.

Market Price

The YG0323 Ultra-Low Temperature Freezer is available in the $13.544 – $13.600 USD price range, depending on optional features like CO₂ or LN₂ backup systems, data logging, or additional storage racks. This investment guarantees high reliability, precision control, and long-term sample preservation, making it an ideal choice for laboratories and medical facilities requiring stable ultra-low temperature storage.
