TrB III Trigger Box – All-in-One Flow Controller
The TrB III Trigger Box ensures compliance with standard pharmacopeial methods, both recording and storing key system parameters, including the actual flow rate and run duration. Many inhaler test methods rely on critical flow conditions across the flow control valve, aiming to ensure the same flow rate on each test. But the TrB III does more – actually measures the flow of each test – so, there are no assumptions.
A calibrated laminar flow element (LFE) internal to each TrB III enables the user to set the flow rate at the beginning of a test sequence; with this LFE, the TrB III then records the flow rate of each test, ensuring against drift, leaks, and other non-ideal behavior that may introduce variability in test results. The TrB III also records the other more traditional run-time parameters, such as the test duration, the pressure drop across the inhaler device (P1), and the flow control pressure ratio (P3/P2, critical flow if ≤ 0.5).1
Additional user-friendly functions are leak checking and synchronized device actuation by using the integrated output port. Device actuation enables the flow to start simultaneously with dose actuation of a metered-dose inhaler, allowing a user- defined, fixed flow volume for MDI total dose testing.

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.

Mixing Inlet - Air-Flow Moderating Inlet (AMI)
The purpose of this product is inhaler testing aimed at achieving greater clinical relevance when testing dry-powder inhalers. Much like traditional mixing inlets, this product allows the user to maintain a constant flow rate into the cascade impactor with any chosen, time-varying flow rate through the DPI itself. We call it the Air-Flow Moderating Inlet (AMI)…a new friend of the inhaler testing community.

Waste Station Ellipta
This is our dedicated waste station for Ellipta. The user puts the Ellipta in a nest and closes a safety cover. The station then automatically mates the inhaler with the mouthpiece adapter, withdraws dose and then reverts. The process is repeated according to a user defined number, with selectable delay-time in between. 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.
