EQius™ stoppers

EQius™ Equilibrium RH Stabilizers are sorbent products that maintain a certain humidity level in pharmaceutical packaging in cases where specific relative humidity conditions are required.

This is specifically of interest to protect Dry Powder Inhalers, Gelatin capsules, Gummies or Marijuana products.

An equilibrium sorbent performs like a humectant (desorber) and desiccant (adsorber) for applications requiring a specific Equilibrium Relative Humidity (ERH) range inside product packaging. EQiusTM can be filled in different platforms as packets, capsules, stoppers or bags to answer specific applications needs.


  • Sensitive formulations protected: Dedicated Relative Humidity levels are available to fit the needs of Dry Powder Inhalers (DPIs), bulk powder prior to processing…
  • Sensitive drug forms protected: Hard and soft gelatin capsules to optimize their performance and delivery.
  • Wide range of products: Configurations include packets, capsules, stoppers and bags at different equilibrium levels from 10% to 90% RH.
  • Standard or customized:  An array of standard products is available, whether off-the-shelf or make-to-order, with customization available.
