Vereo® Automated Actuators
Proveris’s patented Vereo® automated actuators reliably replicate hand use of nasal and oral spray pumps and metered dose inhalers. Vereo actuator MicroDrive™ technology provides pinpoint accuracy for single-device shot weight and dose content uniformity tests. Moreover, Vereo actuators are the heart of all SprayVIEW® spray pattern and plume geometry measurement instrumentation, and the heart of Indizo® high volume, automated shot weight and dose content uniformity instruments.
Vereo actuators are available in configurations for all types of nasal sprays, including side-actuated and dual-actuated (squeeze bottle) devices. They are also available in configurations for oral sprays and metered dose inhalers.
Powered by Proveris’s Viota Software Platform
Operating through Proveris’s Viota® software platform, Vereo actuators provide the following automated features and benefits:
- Automatic instrument verification, force transducer, calibration, and pump stroke characterization to the Viota software platform
- Programmable velocity and acceleration profiles that users define, store, recall, test, and execute using Viota software
- Real-time force and stroke position data display and recording through the Viota software platform for each spray actuation event to simplify process control and method harmonization
- User-settable calendaring of re-calibration frequency with automatic enforcement
Proveris’s Vereo actuators meet or exceed FDA and U.S. Pharmacopeia recommendations regarding the measurement capabilities, validation status, reliability, and accuracy for automated actuation instrumentation used in pharmaceutical spray testing.
Vereo actuators are designed to satisfy stringent FDA guidelines for using an automated actuation system when performing FDA recommended tests. Pharmaceutical spray and aerosol drug developers around the world and the FDA have standardized testing methods around Vereo actuators.
Vereo actuators can also be used with Malvern Instruments’ Spraytec equipment for single-device tests that employ laser diffraction to measure droplet size distribution, or with cascade impactors to perform particle size distribution tests of nasal sprays and metered dose inhalers.
