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.

Does this unit require liquid nitrogen?

Units of this type, including the Grant CRF-1, typically require a supply of liquid nitrogen (LN2) to achieve and maintain their low temperatures and controlled cooling rates. Buyers should confirm LN2 requirements with the seller.

What sample types can be frozen in a CRF-1?

Controlled rate freezers are designed to freeze a wide array of biological samples, including cells, tissues, blood products, and other biological materials in cryovials, bags, or other suitable containers.

What maintenance is typically required for a controlled rate freezer?

Routine maintenance commonly involves checking and calibrating temperature sensors, inspecting LN2 lines for leaks, and ensuring the control system is functioning correctly. Regular cleaning of the chamber is also recommended.

Is specialist installation required for this equipment?

Installation typically involves connecting to an LN2 supply and a suitable power source. Depending on the laboratory setup, specialist handling of LN2 and calibration may be required.

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.

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.
