Thermo Scientific TSX505 Series SAN DIEGO, Calif. – AACC – (July 31, 2017) – Clinical and laboratory personnel with the need to store vaccines, pharmaceuticals and other molecular or biological samples safely can benefit from a new series of lab-grade undercounter refrigerators that are designed to minimize energy usage and noise, while maintaining high levels of performance and maximizing storage capacity.  

The Thermo Scientific TSX505 Series undercounter refrigerators will debut at the 69th AACC Annual Scientific Meeting & Clinical Lab Expo (booth 4039), July 30-August 3, in San Diego, CA.

As the only current lab-grade undercounter refrigerators using thermoelectric devices in place of compressor technology for variable speed control, these refrigerators regulate their internal temperatures more effectively to provide ideal storage conditions for the most demanding applications. Powered by compressor-free V-Drive technology, featuring synchronized temperature management (STeM), internal conditions are actively monitored and maintained at the desired temperature. This includes constant monitoring of, and adjustments during, door-openings to minimize the negative impact of temperature fluctuations on samples. In combination, V-Drive and STeM provide uninterrupted temperature stability and uniformity throughout the internal chamber. Furthermore, the new TSX505 refrigerators consume up to 37 percent less energy than other models, translating to an average annual cost reduction of up to 30 percent.

The compressor-less technology of the TSX 505 refrigerator also overcomes the common challenge of ‘humming’ experienced with many lab-grade refrigerators through its whisper-quiet operation at just 35 dBA. This means that the unit can be kept in work areas without disturbing personnel or nearby patients.  In addition, with no internal protrusions, such as overhead fans, users can benefit from up to double the storage space compared to similar models. 

“Our customers often deal with highly sensitive samples that need to be maintained at constant temperatures to preserve their viability for use, which is especially important in the clinical setting,” said Eric Roman, president, laboratory products, Thermo Fisher Scientific. “For many, it’s essential that vaccines and other medicines are located close to the patient to boost efficiencies, which is why we focused on decreasing refrigerator noise to reduce the level of disturbance at the point of care. This, in combination with the sustainability focus of the entire TSX portfolio, enables us to bring to market a product designed to eliminate real laboratory issues in a number of settings.” 

As the latest addition to the Thermo Scientific TSX Series of freezers and refrigerators, the undercounter refrigerators use environmentally-friendly refrigerants in compliance with the U.S. Environmental Protection Agency’s (EPA) Significant New Alternatives Policy (SNAP). Data logging capabilities are easily enabled through a USB port, allowing users to monitor storage conditions in a timely and efficient manner.
