Grant CRF-1 Controlled Rate Freezer

• Cell and tissue preservation in research laboratories.
• Controlled freezing of biological samples for long-term storage.
• Cryopreservation of gametes and embryos in fertility clinics.
• Temperature-controlled freezing for pharmaceutical development and testing.

Typical capacity

Units of this type typically accommodate various sample formats, such as cryovials, bags, or plates, often with multiple shelves or racks.

Temperature range

Controlled rate freezers commonly offer a temperature range down to -80°C or lower, with precise control over cooling rates.

Cooling rate

This class of equipment typically provides programmable cooling rates, often ranging from 0.01°C/min to several degrees per minute.

Power supply

Commonly found on units of this type is a standard single-phase electrical supply, typically 230V, 50Hz for the UK market.

Refrigeration method

Controlled rate freezers often utilise liquid nitrogen (LN2) as the primary cooling agent, with electronic control.

Footprint

For this class of equipment, the footprint can vary, but benchtop or compact floor-standing designs are common, requiring moderate laboratory space.

• What is a controlled rate freezer used for?

  A controlled rate freezer is used for precise, programmable freezing of biological samples to minimise cellular damage during the cryopreservation process. This is crucial for maintaining sample viability.

• Is specialist installation required for this equipment?

Blast freezers hold strong reputations for reliable performance in food processing operations. Buyers typically prioritise units with sturdy construction and consistent temperature control, as these directly affect product quality and shelf life. When purchasing used equipment, inspecting refrigeration systems, door seals and internal surfaces for wear is essential. Industry sentiment favours models from established manufacturers known for durability. Key strengths include rapid freezing capability, energy efficiency compared to older freezing methods, and adaptability to various food types. Proper maintenance history significantly influences buyer confidence in used units.
