Desiccant washers provide protection from moisture as alternatives to drop-in style desiccants. Assembled to the inside of standard pharmaceutical caps, desiccant washers rest in the neck of pharmaceutical containers instead of intermingling with package contents.

Washers are compatible with commonplace screw-on caps, including those with tamper-evident and child resistant features. Benefits include:

• Desiccant washers are conveniently integrated into pharmaceutical closures.
• Desiccant washers remain in the cap, ensuring that container remains desiccated even after opening.
• Desiccant washers can be customised to meet customer needs.
