Thermo Fisher Scientific - Thermo Scientific TSX40086V Ultra Low Temp Freezer

• Long-term storage of biological samples such as DNA, RNA, proteins, and cell lines.
• Preservation of pharmaceutical compounds and drug substances requiring ultra-low temperatures.
• Storage of sensitive reagents and chemicals in research and development laboratories.
• Cryopreservation of clinical samples in biobanks and healthcare facilities.

Typical capacity

For this class of equipment, capacities commonly range from 400 to 700 litres (approx. 300 to 600 box capacity).

Temperature range

Units of this type are designed to maintain temperatures typically between -50°C and -86°C.

Power supply

Commonly requires a dedicated single-phase electrical supply, typically 230V, 50Hz, with a specific amperage rating.

Refrigeration system

Often features a cascade refrigeration system, utilising natural refrigerants for energy efficiency.

Footprint

Typically a vertical upright design, requiring a floor space of approximately 1m x 1m.

Insulation

Units commonly incorporate vacuum insulation panels (VIP) and foamed-in-place polyurethane for thermal stability.

• What is the typical energy consumption of an ultra-low temp freezer?

  Energy consumption varies significantly based on model, age, and usage patterns. Modern units, like the TSX series, are designed for improved energy efficiency compared to older models.

• What maintenance is required for a unit like this?

• Can this freezer be connected to a building's alarm system?

• What are the common installation requirements?

• Is a CO2 or LN2 backup system typically available for these freezers?

Laboratory freezers hold strong reputations for reliable sample preservation across biotech and pharmaceutical settings. Buyers typically prioritise temperature stability, storage capacity, and energy efficiency when selecting used units. Key considerations include verifying maintenance history, checking door seals and compressor condition, and confirming accurate temperature control calibration. Industry sentiment values freezers offering consistent performance and minimal sample degradation. Established brands generally command preference due to proven durability. Used models often deliver good value when properly serviced, though buyers should assess age and usage patterns carefully before purchase.
