FAQ

What is a Lyophilizer and how does it work?

A Lyophilizer, also known as a freeze dryer, removes moisture from materials through sublimation. Under vacuum conditions, frozen water changes directly from ice into vapor without passing through the liquid phase. This process helps preserve the original structure, activity, and quality of heat-sensitive materials.

What materials can be processed with a Lyophilizer?

Lyophilizers are widely used for drying heat-sensitive materials, including biological samples, pharmaceuticals, vaccines, enzymes, microorganisms, plant extracts, food products, and laboratory research samples. The freeze-drying process helps maintain product stability and improve long-term storage performance.

How do I choose the right Lyophilizer model?

The suitable model depends on sample volume, moisture content, required freeze-drying area, condenser capacity, and specific process requirements. Chendun provides different CDFD Series Lyophilizers to meet laboratory research, small-scale production, and customized freeze-drying applications.

What vacuum level can the CDFD Series Lyophilizer achieve?

The CDFD Series Laboratory Lyophilizer can achieve a vacuum degree of less than 10 Pa, creating an efficient vacuum environment for sublimation and ensuring stable freeze-drying performance.

Does the Lyophilizer support customized freeze-drying programs?

Yes. The CDFD Series Lyophilizer features an intelligent control system with programmable freeze-drying recipes. Users can adjust shelf temperature, set multiple process segments, record operation data, and optimize drying parameters for different materials.
