Inhalation preparation drug tester Shanghai Chengwei

Inhalation preparation drug tester one, the implementation standard in line with YY/71743-2021 for the instrument of the standard two, technical parameters 1.
The flow rate from 15L/min to 100L/min adjustable; 2.
Contains 7 layers of impactor and a micro-hole collector; 3.
With 8 movable collection cups; 5.
The impactor contains a pre-separator, which can be used to detect inhaled aerosols, inhaled sprays, inhaled powder aerosols and inhaled liquid preparations
.

The pre-separator can effectively remove large particles of 10-15 μm generated by the dry powder inhaler; 6.
The collection cup is the impact surface, placed on the tray, directly below the nozzle; 7.
The dose uniformity test
of inhaled powder aerosol, inhaled aerosol and inhaled spray can be completed.
