Thermo Fisher Scientific 88400V Freezer: Ultimate performance for storage at -86°C
Designed to provide safe and reliable storage for sensitive samples, the 88400V Freezer from Thermo Fisher Scientific is a benchmark appliance for laboratories seeking the highest level of performance. With its generous 548-litre capacity, it can store up to 400 standard 2-inch boxes while maintaining a uniform temperature ranging from -50°C to -86°C. This model meets strict safety and control standards while ensuring maximum energy efficiency.
At the heart of the 88400V Freezer is a dual-stage cascade refrigeration technology, incorporating two high-performance hermetic compressors. This industrial system maintains extreme temperatures continuously, while reducing mechanical stress on components. The configuration also includes a cold wall evaporator treated for better thermal conductivity, ensuring uniform cold distribution throughout the interior chamber.
The user interface is simple and intuitive thanks to a microprocessor control system with touch screen. This controller not only allows precise setting of temperatures and alarms, but also data recording and export via a USB port. Integrated safety features such as an automatic voltage backup system (Buck/Boost), high/low temperature alarms, and an RTD temperature sensor ensure continuous monitoring of internal conditions. If necessary, remote alarm connections allow for a quick response.
In terms of design, the freezer is robust, ergonomic and designed for intensive professional use. It has three adjustable stainless steel shelves, each supporting up to 73.4 kg. The external dimensions are optimised (1981 x 960 x 818 mm) to fit easily into any laboratory environment, while high R-value vacuum insulation panels and polyurethane foam ensure excellent thermal insulation. The reinforced silicone door seal with perimeter heating ensures a perfect seal.
The 88400V Freezer is compatible with advanced options such as LN2 or CO₂ backup systems, a graphic recorder or HID-controlled access, further enhancing the reliability of the unit. This model is therefore the ideal solution for research laboratories, biobanks and hospitals requiring reliable ultra-low temperature storage.
