Glass Frit Impinger DUSA

Used as an alternative to the DUSA after proper equivalence testing (ask us how!). Used by many of the leading companies within OINDP testing. This filter comes in various forms but adheres to the principles which was published in a USP stimuli article 1993. ¹  It lends itself to high-capacity testing and automation since it is washable with good recovery and minor carry-over.

Dose Station Turbuhaler ®

This is our dedicated delivered dose uniformity test station for Turbuhaler ®, using the brilliant impinger filter dose collector. The latter is washable in-situ and can be ready for the next dose as part of the wet chemistry work-up procedure. The user works with the equipment in a fixed process which starts by the user placing the device in an inlet which mates with the dose collector. The inlet is a highly sophisticated construction with an inflatable gasket which seals around the mouthpiece. Above the gasket there are channels which efficiently rinses the gasket and the filter with solvent. The user is aided by the station with functions such as dose actuation, solvent delivery, sample agitation and dose collector cleaning, after which the user collects the sample manually. The process is ended with an automated drying procedure. The integration with FIA’s TriggerBox III gives the user full control of the flow process and relevant data recorded on file or printer. Turbuhaler ® is one of the devices on this product category, see also Ellipta ® implementation, but can be made for essentially all devices upon customer request. See also attached flyer for in-depth information.

Automated Waste Station Turbuhaler/ICORes

can be customised according to your device, the example shown here is for Turbuhaler/ICORes. The station can be made to withdraw doses in different angles, i.e., different orientation of the device, to overcome “memory effects” of reservoir inhalers. Actuation can be by push, pull or as shown here, with a twist. The doses are collected on a high-capacity filter, with a holding capacity of about 10 g. The disposable filter is then safely and easily replaced. The integration with FIA’s TriggerBox III gives the user full control of the flow process and relevant data recorded on file or printer. Can be equipped with anti-static-device. See here for more information.
