High-Precision Bag on Valve Spray for Pharmaceutical Inhalers with Micro-Dosing Control & Sterile Packaging
Product Description:
Our bag on valve spray technology sets a new standard for pharmaceutical inhalers, delivering micro-dosing accuracy critical for respiratory treatments like asthma and COPD medications. The airless BoV system ensures each dose is protected from contamination, as the product remains isolated in a sterile inner bag until dispensed. This design eliminates the need for preservatives, extending shelf life and improving patient safety. The precision-engineered actuator releases doses as small as 25 µL with ±5% deviation, meeting FDA and EMA regulatory requirements. Compatible with HFA propellants or compressed air, these sprays offer a quieter actuation than traditional metered-dose inhalers (MDIs), enhancing user compliance. The single-use sterile packaging prevents cross-contamination in hospitals and clinics, while the tamper-evident seal guarantees product integrity. Customization options include dose counters and breath-activated triggers for pediatric use. Trust our BoV sprays to elevate the reliability and efficacy of your respiratory therapeutics.
Bullet Points:
- Bag on valve spray with micro-dosing accuracy (25–100 µL per actuation).
- Airless design eliminates preservatives and extends shelf life.
- Sterile single-use packaging for hospital environments.
- Quiet actuation improves patient experience.
- Compatible with breath-activated mechanisms.
Specific Application Scenario:
Used in rescue inhalers to deliver precise albuterol doses during asthma attacks, ensuring rapid relief without overdosing.
