- Rapid Measurements at acquisition rates of up to 10 kHz capture the dynamics of any spray process in exceptional detail.
- A Patented High Concentration Analysis delivers accurate spray results at spray concentrations where other techniques would simply fail.
- Automated software and advanced analysis features ensure repeatable aerosol measurements can be made, time and again.
- Hardware Design : Learn more about how the Spraytec measures spray particle size distributions.
- Software Functionality : The Spraytec’s software provides many advanced features to ensure users get the most from the system’s extensive spray and droplet sizing capabilities.
- Pharmaceutical Applications : Discover how Spraytec is aiding researchers in developing and testing nasal spray, inhaler and nebulizer drug delivery devices.
- Industrial Applications : Find out how the Spraytec enables the routine characterization of industrial spray systems such as fuel injectors, agrochemical sprays and coating sprays.
Accessories
A range of accessories is available for use with the Spraytec system these further enhance the measurement capability of the instrument.
Accessories for Nasal Spray Testing: The Spraytec Nasal Spray System (NSS) is intended to help users in the pharmaceutical industry meet FDA recommendations for the testing of nasal sprays and aerosols.
Inhaler and nebuliser testing: The Spraytec's unique Inhalation Cell enables the rapid characterization of pharmaceutical inhalers and nebulisers.
Aerosol Mount: Enables to accurate positioning of aerosols and sprays relative to the Spraytec measurement zone.
Purge System: Designed to enable continuous operation of the Spraytec without spray droplet contamination when measuring extremely wide spray plumes.
Wet Dispersion Accessory: Enables the measurement of powders, suspensions and emulsions using the Spraytec system.
Extraction Systems: HEPA rated extraction systems to reduce the risk of operator exposure to the spray for laboratory spray measurements.
