ERWEKA TPK 2 valve box for pharmacopoeial dry powder inhaler airflow and dose testing.
The ERWEKA Copley TPK 2 Valve Box is a pharmaceutical testing unit and critical flow controller for dry powder inhalers (DPIs). It regulates airflow from a vacuum pump to help meet current pharmacopoeial test requirements.
For dry powder inhaler testing, the emitted dose and fine particle dose depend on the strength and duration of patient inspiration. The TPK 2 allows the operator to adjust airflow accordingly and supports controlled inhaler performance evaluation in pharmaceutical quality control and inhalation research.
The unit is described as being in very good cosmetic condition and 100% functionally tested.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
