Floor Model Standard Freeze Dryer LFFD-A14

Manifold freeze dryers are compact, cost-effective, and ideal for small-scale or multi-sample operations. They offer flexibility in handling different sample types at the same time. Unlike shelf dryers, which require uniform trays and temperature control, manifold systems allow individual flasks to be freeze-dried under vacuum. This setup is particularly useful in research settings where small volumes and varied sample types are processed. They also provide easy access and visual observation of the drying process. Although, there are certain limitation associated to such freeze dryers such as extensive power consumption and cost factor.

Freeze drying, or lyophilization, differs significantly from dehydration. Dehydration involves removing water through heat or drying, which can damage food's structure and nutrient content. Freeze drying preserves the original shape, texture, and nutritional value of the food by removing water while frozen and under vacuum. It removes solvent by the method of sublimation.

Freeze drying offers several advantages over other preservation methods. It preserves the sample’s original shape, texture, and nutritional value, resulting in a longer shelf life. It also allows for convenient storage and rehydration without compromising the quality. Labtron’s Floor Model Standard Freeze Dryer is ideal for freeze drying of a sample to preserve for long duration.

Our Floor Model Standard Freeze Dryers are compatible with a range of vacuum pumps. User can select the vacuum pump according to their needs. We offer Two-stage rotary pumps with different ultimate vacuum and pumping rate. Also, scroll dry pump, chemical hybrid pump and more are available to buy.

The cold trap in a freeze dryer serves to capture and freeze water vapor released from the sample during sublimation. By condensing the vapor before it reaches the vacuum pump, it prevents potential damage and contamination. This helps maintain the efficiency and longevity of the vacuum system. Regular defrosting is needed to keep the cold trap functioning properly.

Labtron’s Floor Model Standard Freeze Dryer features shelves with holes for centrifuge tubes. Always use the compatible containers for freeze drying your sample. Generally, flasks, vials or trays made from stainless-steel or glass are used. Our freeze dryer has freely movable shelves and their height is also adjustable. One can use a versatile range of flasks.
