Floor Model Standard Freeze Dryer LFFD-A16

The Standard system consists of a central drying chamber or condenser unit with several ports where flasks or containers can be attached. Each port connects to a sample via a valve, and once all the samples are secured, a vacuum is applied. Under low pressure, the frozen water in the samples sublimates and is captured in the condenser. The Standard allows each flask to be individually exposed to vacuum, ensuring uniform and independent drying. Some models also allow individual isolation of ports, so samples can be added or removed without disturbing others.

Our Floor Model Standard Freeze Dryer typically requires external vacuum pumps. Oil-sealed rotary vane pumps are most common due to their ability to achieve deep vacuum levels and handle water vapor efficiently. However, dry scroll pumps are also used, especially in clean environments, since they reduce contamination risk and require less maintenance. The choice of pump depends on the specific drying requirements and the compatibility with the solvents or vapors being processed.

Yes, Labtron’s Floor Model Standard Freeze Dryer comes with several safety features. These may include over-temperature protection, and vacuum failure alarms. It also has a large opening and passage design. The thermal electromagnetic over current short circuit protection ensures a safe operation.

Standard 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, Standard 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.

Yes, the transparent acrylic chamber is designed for both durability and clear visibility, allowing users to monitor the drying process safely. Labtron’s products are known for their precision and durability. We end to use highly durable materials and components for construction of all of our products. Our Floor Model Standard Freeze Dryer is built with a durable acrylic chamber.
