Proveris Scientific VEREO - Automated Actuation System for PMDI Inhaler Devices

SHARE

The Automated Actuation System by Proveris Scientific is designed to optimize the performance of pressurized metered-dose inhaler (pMDI) devices by implementing consistent automated actuation, thereby eliminating manual variability. This system precisely controls actuation parameters such as stroke length, velocity, acceleration, and force, making it an ideal choice for conducting repeatable in-vitro tests including spray pattern analysis, plume geometry, and dose content uniformity. It features an integrated shake axis for efficient shake-to-fire intervals essential for unstable formulations. The electromechanical framework ensures high accuracy without the need for compressed air. When used with Viota software, this system provides comprehensive valve performance insights. It can function independently or as part of a larger analytical setup, aligning with regulatory guidelines to offer a robust, efficient solution for aerosol drug delivery testing.

Unrivaled Performance in Automated Actuation

Automated actuation and shaking of pMDI devices eliminates the variables of manual actuation, and keeps parameters consistent across tests. The system ensures precise, reproducible control of stroke length, contact and end-of-stroke limits, actuation velocity/acceleration, hold time, and release velocity/acceleration. In addition, an integrated shake axis with shake angle and frequency control offers rapid shake-to-fire interval for unstable suspension formulations.

Uniform, Consistent Actuation—Every Time

  • Robust, proven functionality lets you model human usage of your product, ensuring precise control of important actuation parameters, including force limit, position, velocity, acceleration, and timing
  • Electromechanical design offers superior control, accuracy and precision—no compressed air or vacuum required
  • Can operate as a standalone benchtop unit or within a Proveris platform, Cascade Impactor (ASPD), or other analytical instruments.
  • Together with Viota® software, offers valuable insight into valve performance, and lets you investigate position and force profiles for each actuation
