Arctiko UK TF220 Ultra Low Temperature Freezer

• Long-term storage of biological samples such as DNA, RNA, proteins, and cell lines in research laboratories.
• Preservation of pharmaceutical products, vaccines, and diagnostic reagents requiring stable ultra-low temperatures.
• Storage of industrial materials and components sensitive to temperature fluctuations, such as certain chemicals or electronic parts.
• Use in clinical laboratories for storing patient samples and reference materials.

Typical capacity

For this class of equipment, capacities commonly range from 100 to 250 litres, suitable for various sample volumes.

Temperature range

Ultra-low temperature freezers typically operate between -50°C and -86°C, ensuring critical sample integrity.

Power supply

Units of this type commonly require a 230V, 50Hz single-phase power supply, typical for UK laboratory environments.

Footprint

These freezers are typically upright or chest designs, with a footprint suitable for standard laboratory spaces, often around 0.5 to 1 square metre.

Refrigeration system

Commonly features a cascade refrigeration system using natural refrigerants for efficient and stable cooling.

Insulation

Typically includes high-density foam insulation and multiple inner doors to minimise temperature loss during access.

• What is the typical lifespan of an ultra-low temperature freezer?

  With proper maintenance, these freezers can typically operate reliably for 10 to 15 years, though specific unit longevity varies.

• What are the common maintenance requirements for this type of freezer?

• Does this unit require a dedicated power circuit?

• What are the considerations for installation?

• How important is temperature uniformity within the freezer?

Laboratory freezers are viewed as essential, reliable workhorses in research and pharmaceutical settings. Buyers typically prioritise consistent temperature stability, particularly for sensitive sample preservation. When purchasing used units, inspectors should verify compressor condition, assess temperature uniformity across shelves, and confirm calibration records. Key strengths include durability across decades of operation and relatively straightforward maintenance. Buyers value models with robust insulation and dependable controls. Common considerations involve checking door seals and verifying energy efficiency ratings remain acceptable for modern laboratory standards.
