Overview

The Blizzard NU-99728J Ultralow Freezer from NuAire offers unparalleled cold storage for critical stem cells, blood, tissue samples, and vaccines. Its vacuum-insulated panels and dual compressor system ensure consistent, efficient temperature management, making it an essential asset for any lab prioritizing sample integrity and sustainability. Trusted for its robust construction, ergonomic design, and low-noise operation, it's backed by NuAire's commitment to quality and customer satisfaction.

Maximize Lab Efficiency with Smart Control Freezer

Our Ultralow Freezer features an advanced electronic control system strategically placed at eye level, making monitoring crucial data at a glance effortlessly accessible. This intelligent interface not only displays the internal temperature, ambient temperature, and voltage in real time but also ensures the safety of your precious samples with an integrated audible and visual alarm system. With several indicator lights, users gain insight into the freezer's condition: operational status, alarm triggers, or maintenance alerts. The intuitive navigation arrows and set key empower users to customize access via passcode, adjust temperature settings, define alarm limits, and tailor freezer preferences to their specific needs, enhancing security and operational efficiency in your laboratory environment.

Secure & Efficient Storage with Advanced Insulation

The Ultralow Freezer NU-99728J revolutionizes dependable research storage with its cutting-edge insulation and refrigeration system. Featuring insulated inner doors with individual latches, it ensures temperature stability, which is vital for the integrity of sensitive samples. Vacuum Insulated Panels (VIP) combined with high-density, low-conductivity polyurethane foam enhance temperature uniformity and maximize storage capacity, making every inch count. Hydrocarbon (HC) refrigerants, an eco-friendly choice, offer efficient cooling without harming the ozone layer. The quadruple outer and single-gasket inner doors create a pressure-tight seal, drastically reducing icing and thermal intrusion. This freezer is designed to meet the rigorous research storage demands, providing peace of mind with every use.

Effortless Access with Smart Freezer Design

Blizzard Ultralow Freezers are engineered for seamless access without compromising sample security or temperature stability. The innovative Pressure Equalization Port, equipped with a heated, spring-assisted mechanism, ensures the freezer door can be easily opened right after sample insertion, preventing icing. The outer door features a locking claw latch that maintains a tight seal to minimize frost build-up and allows for effortless opening with minimal effort. The door includes a key lock and padlock option for enhanced security, ensuring your valuable research materials are safeguarded. Inside, individual latching inner doors maintain pressure-tight sales, making organizing and accessing samples straightforwardly without affecting the entire storage environment. This freezer combines practical usability with the stringent security measures essential for high-value research storage.

Seamless Data Management in Freezers

The NU-99728J Ultralow Temperature Freezer introduces seamless data management and connectivity for modern laboratories, featuring a USB Data Port for easy download of freezer data directly from the electronic control center. With a standard remote alarm and RS485 ports in the power switch panel, this freezer allows for the transmission of temperature and alarm data to independent software for comprehensive monitoring and recording. An optional Circular Chart Recorder offers an extra layer of data reliability with internal temperature monitoring and recording, ensuring your research data is accurately tracked and securely managed. This integration of advanced connectivity options ensures that Blizzard ULTs meet and exceed the data management needs of today's fast-paced scientific environments.
