The Thermo Scientific TSX Core Series ULT freezer stores samples stably between -50°C and -86°C. Therefore, this unit suits long-term storage in busy laboratory environments. Furthermore, the temperature stays evenly distributed across the entire cabinet, even with frequent door openings. Additionally, the unit protects not only the samples, but also the research they represent. The series offers four capacities, from 547 to 950 litres. As a result, each model fits the available space and the required storage volume.
The TSX Core Series operates with the Variable Drive (V-Drive) compressor technology from Thermo Scientific. Therefore, the compressor adjusts its speed steplessly to the required cooling capacity. Furthermore, this variable operation limits temperature fluctuations, unlike standard compressors that only switch on or off. Additionally, this approach increases energy efficiency and reduces wear. The key performance features are:
Each model features an intuitive control panel with a 5.6 inch capacitive touch display. Therefore, you manage settings and adjustments quickly through five touchpoint buttons. Furthermore, the unit operates whisper-quiet, below 44 dBA. Additionally, the unit is fitted with universal voltage (100-230V, 50/60Hz), so installation is easy worldwide. The key usability benefits are:
The TSX Core Series fits a wide range of research and diagnostics applications. Therefore, it is a reliable choice for the long-term storage of valuable samples. Furthermore, each unit ships with a factory acceptance test report and a certificate of calibration. Additionally, these freezers fit well within the pharmaceutical industry and biotech and medical diagnostics.
The TSX Core Series ULT freezer is part of the Thermo Scientific range within our ULT freezers. Therefore, Poly Temp also provides advice on installation and maintenance through our service and maintenance team. Do you have questions about the right choice? Then contact us via our contact page.

The TSX Core Series ULT freezer cools between -50°C and -86°C. Therefore, the unit suits long-term storage of temperature-sensitive samples.
V-Drive is the Variable Drive compressor technology from Thermo Scientific. The compressor adjusts its speed steplessly, which keeps the temperature more stable and lowers energy consumption.
There are four models: 547, 682, 815 and 950 litres. As a result, each model fits the available space and the required storage volume.
The capacity ranges from 400 boxes (2 inch) in the smallest model to 700 boxes in the largest model. Therefore, the series offers room for a variety of storage needs.
Yes, the unit operates below 44 dBA. Therefore, placement directly in the laboratory is possible, without disrupting the work environment.
The series operates on universal voltage from 100 to 230V, at 50 or 60 Hz. Therefore, installation is easy worldwide.
