Glass Expansion Chambers
The use of a cascade impactor together with a high volume expansion chamber is used to measure the amount of drug in small particles or droplets in respect of nasal sprays and aerosols. In accordance with the draft guidance, we offer a range of glass expansion chambers to meet these requirements. We offer 3 sizes:
1 L chamber: to maximise drug deposition below the top stage of the impactor (i.e. for nasal aerosols)
2 L chamber: to maximise aerosolisation and impactor deposition (i.e. for nasal sprays)
5 L chamber: for powerful nasal sprays where increased space is required to generate full plume
