The plasma blast freezer, also known as a plasma freezer or blast freezer, is a groundbreaking sample preparation device designed for the rapid freezing and preservation of active components such as plasma, vaccines and biological samples. It is tailored to meet the specific requirements of various settings, including plasma collection centers, hospital blood transfusion departments, CDC vaccine storage facilities, and laboratories requiring long-term sample preservation. Complying with GMP regulations and performing reliably in high-temperature, high-humidity environments.
Forced-air cooling system, two compressors, and PT1000 sensors for precise temperature control, it maximises the preservation of sample viability.
A VIP vacuum insulation panel combined with rigid thermal insulation delivers exceptional thermal performance. corrosion-resistant US304 interior, easy to clean.
The stainless steel interior is corrosion-resistant and easy to clean.
Multiple layers of protection, supports a power-on delay function to prevent accidental operation and eliminate potential safety hazards.
Eco-friendly, pollution-free refrigerants, average daily power consumption 7.85–9.45 W, striking a balance between energy efficiency and operational comfort.
