Expand Your Research with Unmatched Storage Capacity

Unlock the potential of your research with our state-of-the-art freezer, offering a vast 28.7 ft3 (813 L) of storage space. It's tailored for extensive collections, supporting up to 24 racks, 600 boxes, or 60,000 2 mL vials. Precision isn't just a promise; with temperature uniformity of ±4°C and accuracy of ±1°C, your critical samples are maintained in optimal conditions. Ideal for a wide range of applications, from cell preservation to vaccine storage, this freezer is your ally in pushing the boundaries of scientific exploration.

Revolutionize Sample Storage with Advanced Cooling

Elevate your research with our cutting-edge Dual Stage Refrigeration System. This system features two compressors that work in tandem to ensure your valuable research samples are stored under consistently optimal conditions. The rapid recovery of storage temperature post-door openings minimizes thermal shock to sensitive materials, preserving their integrity. Complemented by eco-friendly Hydrocarbon (HC) Refrigerants, our freezer provides efficient and reliable cold storage and safeguards the environment using non-ozone-depleting substances. Trust in our technology to secure your scientific advancements.

Optimize Sample Safety with Superior Insulation Tech

Our freezer is designed with cutting-edge Vacuum Insulated Panels (VIP) and high-density polyurethane foam, ensuring unparalleled temperature stability and maximizing storage capacity. The innovation extends to insulated inner doors, featuring individual latches for compartmentalized storage, further enhancing temperature uniformity. The outer door, equipped with a locking claw latch, minimizes frost build-up and allows easy access without compromising security. Quadruple gasket sealing on the exterior and additional single gaskets on inner doors work synergistically to provide a pressure-tight seal, significantly reducing thermal intrusion and icing. Experience peace of mind with our freezer, where every detail is crafted for the optimal preservation of your valuable research samples.

Ensure Uninterrupted Research with Advanced Safety Features

Maximize your research's safety and continuity with our freezer's cutting-edge alarm systems and backup options. Equipped with audible and visible alerts, our freezers immediately notify you of any internal temperature changes or power disruptions, keeping your valuable samples secure. The optional CO2/LN2 backup cooling systems offer additional protection, maintaining optimal temperatures even during power outages. For temperature monitoring, a circular chart recorder is available. For more precise monitoring, a USB data port enables easy tracking and data transfer, always informing you about your freezer's status. Plus, with a remote alarm and RS485 ports, you can monitor your freezer's conditions from anywhere, providing peace of mind and freeing you to focus on critical research.
