Lyoprotect® Single-use Tray for Sterile Freeze-drying

Simple solution for aseptic bulk freeze-drying of pharmaceutical APIs

Are you looking for a simple solution for aseptic freeze-drying in bulk? At the same time, you wish to avoid an elaborate cleaning process?

With the Lyoprotect® Single-use Tray with Filler Assembly you avoid cross-contamination in your freeze-drier. It offers simple handling and optimum protection of your product and working environment.


Lyoprotect® Single-use Tray with Filler Assembly


Safe Sublimation

During sublimation, the vapor escapes via the hydrophobic ePTFE membrane, which is firmly welded to the single-use tray and ensures a safe cover. The membrane acts as sterile barrier and protects the API against contamination and the working environment and staff against fly-out.

Easy Filling

Thanks to the filler assembly, the Lyoprotect® Single-use Tray can simply be filled via a funnel or tube. An important asset, if time is an issue for the formulation stability.


Filler assembly of Single-Use Tray, cap open

Safe Closure

The cap of the filler assembly is hand-screwed without any tools. Afterwards, the single-use tray can safely be moved to the freeze-drier. Preliminary freezing in a deep freezer is also possible.

For you, this means:  easy filling under the laminar flow for aseptic production, fast closing of the screw-on cap and safe transport between laminar flow and freeze-drier.



The Lyoprotect® Single-use Tray can be sterilized in an autoclave by up to 121°C (250°F) for 20 minutes. The tray must be placed on the edge and the cap must be open for sterilization.
