TrB III Trigger Box Delta – 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). The Delta version can measure pressure drop over, e.g., individual impactor stages to detect blockage, using additional internal sensors.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.

Training and IQ Model III. Can be done remote via Skype or on-site. Request preference. The IQ results in a wet-ink protocol. The user gets a license to copyrighted text for e.g. internal maintenance work. Configurable for inhaler actuation. Configurable for camera sync. Configurable for load cell.
-
Adjustable restrictor to put into flow meter with known inlet (e.g. OD 1/2" or 22 mm, we will work out the ID if model no. is given) to regulate dP of flow into e.g. impactor.
Material: Delrin. -
Volumetric dispenser with a programmable volume in the interval of 10 to 1100 ml. The volume may be repeated to pump several liters in portions. This function may be used for instance to repeatedly fill vessels.
On the picture is shown a product version with a stand. It may also be mounted on a stainless lab trolley or with the lower part under a table.
All parts in liquid contact are corrosion resistant, allowing handling of aggressive liquids and solvents. It is also available for dilution purposes with extra valves.
Easy to operate via touch panel. No PC is needed. Just type in the desired volume in ml and the dispenser will withdraw the volume from the container and dispense it from the outlet.
Different liquids will need different withdrawal and infusion (dispensing) speeds which is easily changed through the panel.
Exact dosage of liquid volumes is in the range of < 10 – 1100 ml. The set volume can be repeated, thus it is also possible to dispense for instance 999 x 1100 ml.
Standard deviation less than 0.02.
Volume accuracy and precision: fault < 0.5 ml in the interval 30 – 300 ml and in the interval 300 – 1100 ml < 0.4%.
The concept can be made in other configurations, such as compact models with shorter but broader cylinders, when a slighty less accurate delivery is acceptable. Lower volume ranges, e.g., 500 ml are also available.

The Controlled Pump is designed to run 32 different pump programs that are easy selectable by two thumb wheels on the front panel. A program consists of one infusion motion and one withdrawal motion which are both configurable with stroke length and speed.
Start a selected pump program by press of the green “START/STOP” push button at the front panel. The pump will start infuse with parameters from the selected pump program. When the pump reach the programmed end position, it will immediately withdraw and then infuse and so on, as long as the latched push button is in its inner position.
