Thermo Scientific TSX3020FD High-Performance -20C Lab Freezer, 230V
The Thermo Scientific TSX3020FD High-Performance -20C Lab Freezer, 230V is a state-of-the-art solution, meticulously designed for the uncompromised storage of sensitive materials such as enzymes, reagents, pharmaceuticals, vaccines, and various biological substances commonly utilized in laboratory and clinical settings. One of its standout features is the innovative V-drive technology, which intelligently adapts compressor speed to usage patterns, efficiently balancing energy savings with rigorous protection standards. This unique system ensures optimal temperature uniformity, particularly during periods of high demand such as door openings, by accelerating compressor activity, and conserves energy during stable periods by reducing speed. Enhanced with cold wall convection cooling, the TSX3020FD maintains stable and uniform temperatures throughout, essential for critical storage requirements. Its user-friendly microprocessor control enables precise temperature management, augmented by an interior light, setpoint security, and integral alarms to safeguard contents reliably. For additional security, standard door locks are installed, delivering peace of mind. Beyond security and performance, the TSX3020FD is designed with the user’s physical comfort and convenience in mind. The ergonomic design features include a door handle with a soft-touch grip, an angled controller to prevent neck strain, and an automatic pressure equalization port for quick reentry following door closures. The unit also boasts easy-to-clean, adjustable epoxy-coated shelves, contributing to the overall maintainability of the freezer. Furthermore, the TSX3020FD respects the need for a quiet work environment, operating at a whisper-quiet 52 dBA to ensure laboratory staff can work undisturbed. The practicality is further enhanced by a self-closing door mechanism, featuring a 90° stop that facilitates convenient inventory management and loading procedures. Overall, the TSX3020FD combines advanced technology with user-centric design, delivering a high-performance freezing solution that does not compromise on security, energy efficiency, or operational comfort. All of our equipment is fully tested to perform at factory specifications before being shipped.
