Lyoprotect® Stainless Steel Tray for Lyophilization

The Lyoprotect® Stainless Steel Tray for Lyophilization, multiple use, is designed for freeze-drying of pharmaceutical APIs (Active Pharmaceutical Ingredients). Thanks to the polished surface, cleaning is easy. The serial number engraved on the tray facilitates the documentation e.g. of the filled-in substances. All components, including the Lyoprotect® Membrane, can be sterilized in an autoclave. APIs can be produced aseptically in compliance with GMP.

The membrane is designed for single use and can be easily replaced before every new drying cycle. During sublimation, the vapor can escape smoothly via the hydrophobic membrane which protects the API against contamination and also protects the working environment and staff against fly-out.

Process development

The dimensions of the Stainless Steel Trays permit individual upscaling. In combination with the Stainless Steel Cups this allows for a continuous process development from a few milliliters in the laboratory up to a filling volume of 6 liters on a GMP production level. Especially in the last expansion stage, it is economically viable to make optimum use of the existing shelves by adjusting the dimensions of tray and membrane accordingly.


The combination of single-use and multiple-use components helps to reduce waste. The highgrade stainless steel tray is very resistant, only the membrane must be discarded.
