Lyophilizer / Freeze Dryer

1. Name of the Instrument: Lyophilizer / Freeze Dryer

2. Working Principle : The Lyophilizer (Freeze Dryer) operates on the principle of freeze drying (lyophilisation), where water or other solvents are removed from frozen samples through sublimation under high vacuum. The sample is first frozen, and under reduced pressure, ice is directly converted into water vapour without passing through the liquid phase. This gentle drying process preserves the structural integrity, biological activity, and chemical composition of heat-sensitive materials, making it ideal for long-term storage and research applications.

3. Applications :
• Preservation of biological samples, microorganisms, cell cultures and food products
• Drying of proteins, enzymes, peptides, and antibodies
• Long-term storage of temperature-sensitive materials

3. Types of Studies: :
Biochemistry, Molecular Biology, Microbiology, Food Science and Technology
