winner 311XP Spray Particle size analyzer

Winner311xp is desktop spray laser particle size analyzer, with a number of patented technology including lens protection device. It could test size of droplet in the air without touch. It’s mainly apply to droplet detection of small spray equipment, such as medical atomizer,atomizing drugs and aerosol.
( Such as Orally inhaled and nasal drug products.
Particle size is a key parameter in defining the deposition pattern and bioavailability of drug materials delivered using pump sprays and inhalers to the nasal mucosa and respiratory system.)

Working Principle:

Main Features:
1) Unique patented technology
Based on laser scattering principle, adopt a single beam of parallel light path and
the dual-lens, dual-array detector technology to ensure high collection of scattering light at different angles, extends the measurement limit, improve the resolution of the instrument.
2) Unique air flow protection device
Airflow protection system can effectively protect the lens to avoid droplet pollution of the lens in the testing process.
For the national pharmacopoeia of inhaled aerosols, sprays, size requirements and the development of inhalation and other desktop spray laser particle size analyzer, can be a variety of aerosols, sprays and other small spray device for testing, integration of micro-nano the company a variety of patented technology, is the best choice of small spray particle size testing
