freeze dryer
Freeze dryers, also known as lyophilizers, are essential in laboratories for preserving sensitive samples by removing moisture under vacuum conditions. Our range includes:
Benchtop Laboratory Freeze Dryer: Compact yet powerful, perfect for small-scale lyophilization with ≤ -60°C cooling.
High Performance Laboratory Freeze Dryer: Advanced models for biopharmaceuticals and food industries, ensuring precise temperature control.
Benchtop Vacuum Freeze Dryer: Features intuitive touchscreen and high-performance refrigeration for efficient sample preservation.
These devices are widely used in pharmaceuticals, biotechnology, and food science to maintain sample integrity during storage and transport.
Our freeze dryers utilize vacuum drying principles to sublimate ice directly from solid to gas, preserving sample structure and biological activity. This process involves:
Freezing Stage: Samples are cooled to -50°C or below to solidify all moisture.
Primary Drying: Vacuum pressure enables ice sublimation without melting.
Secondary Drying: Removes residual moisture at slightly higher temperatures.
Precision Temperature Control: ±1°C uniformity across drying shelves
High Vacuum Levels: 10-30 Pa range for effective sublimation
Modular Designs: Choose between manifold, batch, or bulk processing methods

FAQ
What Is A Freeze Dryer And How Does It Work?
A freeze dryer operates on the principle of vacuum drying. It first freezes water-containing materials into a solid state and then sublimates the water from solid to gas under vacuum conditions, effectively removing moisture while preserving the material's structure and properties.
What Are The Main Applications Of Freeze Dryers?
Freeze dryers are widely used in pharmaceuticals for drug preservation, food industry for long-term storage, scientific research for sample preparation, and biotechnological processes. They are particularly valuable for preserving sensitive materials that would degrade with traditional drying methods.
What Are The Different Freeze Drying Methods Available?
There are three main freeze drying methods: 1) The manifold method for drying different products simultaneously, 2) The batch method for large quantities of identical products, and 3) The bulk method for stable products in tray dryers. Each method suits different production needs and material sensitivities.
What Are The Key Advantages Of Freeze Drying Compared To Other Drying Methods?
Freeze drying offers several advantages: it's a low-temperature process that preserves biological activity, vitamins, flavors, and appearance; materials can be easily reconstituted; and the quality of freeze-dried products is considered closest to fresh material. It's particularly beneficial for heat-sensitive substances.
What Factors Should I Consider When Choosing A Freeze Dryer?
Key factors include: cold trap temperature, cooling rate, ultimate vacuum capability, plate temperature uniformity, application requirements, batch duration, utility consumption (water/electricity), initial investment, and long-term maintenance costs. These factors determine the equipment's suitability for your specific needs and operational efficiency.
What Types Of Freeze Dryers Are Available For Laboratory Use?
Laboratories typically use benchtop freeze dryers that offer ≤ -60°C cooling for lyophilization. These come in various configurations including models with intuitive touchscreen controls, high-performance refrigeration systems, and designs optimized for biological, pharmaceutical, or food samples.
Why Is Freeze Drying Preferred For Pharmaceutical Applications?
Freeze drying is preferred in pharmaceuticals because it preserves the integrity and biological activity of sensitive compounds, extends shelf life without refrigeration, and allows for easy reconstitution of drugs. The low-temperature process is particularly crucial for maintaining the efficacy of vaccines, proteins, and other biological products.
