Freeze-Drying of deepwell plates using Frontloader drying chamber

Deepwell plates, also microwell plate, are often found in pharmaceutical and biological laboratories for processing a large number of samples. In this application note, BUCHI Frontloader drying chamber demonstrates the successful freeze drying of 300 uL deepwell plates using a Lyovapor™ system. combined with the The high number of samples can be freeze dried in one plate allows quick  and easy handling. This includes freeze-drying as well. T

Freeze-Drying of banana sample in Frontloader drying chamber

Fruits such as bananas, with their delicate texture and high moisture content, present unique challenges in preservation. Anyhow, the sample throughput is limited by available surface in freeze dryer since only a monolayers of sample can be dried in parallel. This application note highlights the process parameters, advantages, and outcomes of banana freeze-drying in a Frontloader drying chamber, offering insights into improved stability and storage.  

Contamination-free and sterile freeze-drying using lyophilization bag

Freeze-drying is typically used to deal with sensitive and expensive samples as it offers a gentle drying process. One way to avoid contamination in the drying process is the use of a container with membrane that protect samples from contamination and secondly keep product flyout in place which protects multiple samples from cross contamination.
