The Labconco FreeZone 18 Liter -50°C Console Freeze Dryer is a high-capacity lyophilization system designed for efficient moisture removal from biological and chemical samples. With an 18-liter ice-holding capacity and a collector temperature reaching -50°C, it is suitable for processing moderate to large sample loads.

The FreeZone 18L Freeze Dryer is used for lyophilization, a process that removes moisture from biological, pharmaceutical, and food samples while preserving their structure and stability. It is commonly used in research, medical, pharmaceutical, and industrial settings to extend the shelf life of sensitive materials.

1. Pharmaceutical & Medical Applications

Preservation of Vaccines & Drugs – Ensures the stability and longevity of pharmaceuticals.

Biological Sample Storage – Freezes and dries proteins, enzymes, and blood samples for research.

Tissue & Cell Storage – Used for long-term preservation of tissues and cells in medical studies.

2. Research & Laboratory Use

Sample Preparation – Removes moisture from biological samples for microscopy and analysis.

Stabilization of Chemicals – Prevents degradation of unstable compounds.

Forensic Science – Preserves evidence such as bodily fluids, tissues, and environmental samples.

3. Food & Beverage Industry

Freeze-Drying Fruits, Vegetables, and Meats – Used in food processing to retain flavor and nutrients.

Production of Instant Coffee & Powders – Dehydrates liquid extracts while maintaining taste.

Nutritional Supplements – Preserves vitamins and probiotics in powder form.

4. Biotechnology & Industrial Applications

Lyophilization of Bacteria & Microorganisms – Preserves live cultures for research.

Preservation of DNA & RNA Samples – Maintains genetic materials for experiments.

Production of Cosmetic Products – Used to create powdered forms of skincare and beauty products.

How to Use the FreeZone 18L Freeze Dryer:

Pre-Freezing

Freeze the sample at -50°C or lower to solidify moisture content.

Loading Samples

Place frozen samples in vials, trays, or flasks inside the drying chamber.

Vacuum Activation

Start the vacuum pump to remove air from the chamber, reducing pressure.

Sublimation Process

As heat is applied, the frozen water directly converts into vapor (sublimation).

The vapor condenses on the cooling coil, preventing contamination.

Final Drying Phase

Ensures complete moisture removal, stabilizing the product for storage.

Storage & Packaging

Once dry, samples are sealed in vacuum-sealed containers or sterile vials.

Maintenance Tips:

✔ Regularly clean the condenser and chamber.
✔ Check vacuum pump oil levels to maintain performance.
✔ Ensure a proper seal to prevent moisture reabsorption.
✔ Monitor temperature and pressure using the digital control panel.
