Chest-Freezer 220 VAcAcCTN1 Laboratory Chest Freezer

• Long-term storage of biological samples such as DNA, RNA, proteins, and cell lines.
• Preservation of reagents, enzymes, and pharmaceutical compounds requiring ultra-low temperatures.
• Storage of temperature-sensitive chemicals and materials in research and development settings.
• Use in medical and veterinary laboratories for vaccine and sample preservation.
• Cryopreservation of food samples for quality control and research purposes.

Typical capacity

For this class of laboratory chest freezer, capacities commonly range from 100 to 500 litres.

Power supply

Units of this type typically operate on a standard 220-240V, 50Hz single-phase supply, requiring a stable power source.

Temperature range

Laboratory chest freezers are generally designed to maintain temperatures from -20°C to -86°C, depending on the specific model and application.

Footprint

The footprint varies significantly with capacity, but buyers should consider the external dimensions for laboratory space allocation.

Refrigeration system

Commonly features a cascade refrigeration system or a single-stage system with specific refrigerants suitable for low temperatures.

Insulation

Typically includes high-density foam insulation to ensure temperature stability and minimise energy consumption.

• What is the typical lifespan of a used laboratory chest freezer?

  With proper maintenance, a well-built laboratory chest freezer can have a operational lifespan of 10 to 15 years or more. Regular servicing is key to extending its utility.

• What maintenance is required for a laboratory chest freezer?

• Can this freezer be used for ultra-low temperature storage?

• What are the power requirements for this type of freezer?

• Are there any specific installation considerations?

Laboratory freezers are generally regarded as reliable workhorses in biotech and pharma settings. Buyers typically value consistent temperature stability, energy efficiency, and build quality when selecting used units. Common strengths include robust construction and proven performance across standard applications. When purchasing secondhand, buyers should verify temperature uniformity, inspect compressor condition, check door seals, and confirm maintenance history. Units from established manufacturers tend to hold value and perform reliably with proper servicing.
