Thermo Scientific TSX50086V: a high-performance, reliable and durable ultra-low temperature freezer
The Thermo Scientific TSX50086V is an upright freezer designed to meet the most stringent requirements for the storage of non-flammable laboratory materials. Offering a net volume of 682 litres, equivalent to 500 standard 2-inch boxes, this model stands out for its consistent performance, remarkable thermal stability and construction designed for research, clinical and industrial environments.
This freezer operates in a temperature range from -50°C to -86°C. It features a dual-stage cascade refrigeration system with two hermetically sealed industrial compressors, ensuring maximum cooling efficiency even under heavy loads. The system design, with an improved cold wall evaporator, a forced air-cooled condenser and a capillary tube expansion device, allows for rapid temperature reduction and a quick return to storage conditions after the door is opened. Stability at -80°C is ensured with exceptional uniformity and a return to -75°C in just a few minutes after the door has been open for one minute.
Sample safety is at the heart of the TSX50086V design. It is equipped with 1000 ohm platinum RTD sensors for accurate temperature measurement, remote alarm contacts (RS485/4-20mA), adjustable high and low temperature alarms, a main circuit breaker at the rear and a power switch with lock at the front. The control interface is provided by an intuitive capacitive touch screen, allowing the user to set parameters, view history and retrieve data via a USB port.
In terms of construction, the freezer is extremely robust. It is made of painted steel with a stainless steel option. Insulation is provided by vacuum panels combined with high-density polyurethane foam, ensuring optimal preservation even in the event of a power failure. Watertightness is reinforced by a silicone door seal and an integrated peripheral heating system. The three interior shelves are made of stainless steel, adjustable in 25 mm increments, and can support up to 91.7 kg each.
Designed for modern working environments, the TSX50086V operates silently and is designed for indoor use in ambient conditions between 15 and 32°C. It features multi-directional castors for easy mobility, an automatic electrical backup system (buck/boost) and can be combined with additional options such as a chart recorder or a CO₂ or LN₂ backup system.
This model complies with international safety and performance standards with UL, cUL and CE certifications, ensuring its compliance in laboratories worldwide. Whether for storing vaccines, biological samples, reagents or sensitive materials, the TSX50086V is a reliable and durable choice.
