Here’s how IQF tunnels are used in various areas of the bioengineering and biotech industries:
1. Freezing Biological Samples and Cells
One of the key applications of IQF technology in biotech is the freezing of biological samples, including cells, tissues, and even microorganisms. These materials are highly sensitive to temperature changes, and rapid freezing is crucial for preserving their viability.
-
How It Works: Biological cells, such as stem cells, cancer cells, or bacterial cultures, are flash-frozen using IQF technology. This process involves exposing the cells to extremely low temperatures at high speed, preventing the formation of large ice crystals that could rupture the cell membrane. IQF tunnels provide uniform freezing, which helps ensure that each cell is frozen evenly without damaging its internal structure.
-
Benefits: IQF tunnels help maintain the structural integrity and viability of cells for future research, medical treatments, and bioengineering processes. Rapid freezing also minimizes the risk of cellular degradation, making it ideal for long-term storage of biological samples.
-
Common Products: Stem cells, blood samples, cancer cell lines, bacterial cultures, and other biological materials used for research and medical applications.
2. Freezing Tissues and Organs for Research
In bioengineering and regenerative medicine, tissues and even small organs are often frozen for later analysis, experimentation, or use in bio-printing.
-
How It Works: Tissues, such as skin, cartilage, or other biological constructs, are frozen individually using IQF tunnels. By freezing them quickly and evenly, the process ensures that the tissue retains its structural integrity, cell viability, and other key properties needed for research or clinical applications. This is particularly useful when working with bioengineered tissues designed for transplantation or in vitro experimentation.
-
Benefits: IQF ensures that tissues and organs are frozen without damaging the delicate cell structures or extracellular matrices. This is vital for researchers developing new regenerative therapies or studying disease models. It also allows for longer storage times without the risk of tissue degradation.
