In analytical chemistry, most sample preparations rely on some form of shaking to ensure homogeneity of the formulation. For example, inhaler shaking is an essential step for Metered Dose Inhaler (MDI) and some Dry Powder Inhaler (DPI) testing. Adequate and consistent sample preparation is a key requirement for reliable and repeatable data. For inhaled drug delivery testing, the shaking technique may change the characteristics of the delivered dose.
Automating inhaler shaking reduces the margin for error, ensuring higher, more consistent outputs.
