The new DUSA Shaker from Copley Scientific is a small footprint unit that automates the rinsing of Dose Uniformity Sampling Apparatus (DUSA) collection tubes. Automation not only increases productivity, it also enhances the reproducibility of drug recovery and reduces the risk of operator exposure to repetitive strain injury.  

Dose uniformity testing is mandatory for all inhaled products to confirm consistency from batch-to-batch and across the product lifetime. Individual shots are recovered from a DUSA collection tube by thorough rinsing, post-testing, with an appropriate solvent. This manually intensive agitation process is prone to inter-and intra-operator variability and any failure to adequately wet all internal walls compromises drug recovery and the integrity of the results. 

The DUSA shaker is a novel product designed to ensure full, fast and repeatable drug recovery. It securely holds up to 21 MDI or 12 DPI collection tubes on a series of rollers, subjecting them to a controlled lateral shake and rolling action; shaking frequency and duration can both be set according to test requirements. This process ensures that all internal surfaces are adequately wetted and that agitation is performed with a smooth and yet vigorous action. The unit can be supplied with supporting IQ/OQ documentation and has a footprint of just 570 mm by 610 mm, ideal for the laboratory bench.
