Radiation Shield film for loading doors made of acrylic glass
Loading doors made of acrylic glass have a special, transparent film on the
exterior side of the acrylic glass door. This film reduces the transfer of
radiant heat onto the product and ensures homogeneous freeze-drying
results. It addition, it reduces any potential thawing effects and ensures
safe and quick drying close to the freezing point.
NOTE
Comply with the cleaning instructions concerning the film (see chapter
8.1.2.1 - "Lamination of the loading door with a special film")!
Special equipment: Solvent Shield film for loading doors made of
acrylic glass
The acrylic glass door of the freeze-dryer can additionally be equipped with
a special, transparent and chemical-resistant film that protects the interior
side of the acrylic glass door against aggressive chemicals. As a result,
solvents such as acetonitrile or alcohols, which are very common in freeze-
drying applications, can be used without the need for a stainless-steel door.
The product remains perfectly visible during the freeze-drying process,
thereby enabling unrestricted observation of the product.
NOTE
Comply with the cleaning instructions concerning the film (see chapter
8.1.2.1 - "Lamination of the loading door with a special film")!
