Mechanical pressure-reducing regulator for stable downstream fluid pressure without external power source.
The Western 3003135 Pressure-Reducing Regulator is a precision mechanical device designed to maintain a constant, lower downstream pressure from a higher, variable upstream fluid pressure. It operates without an external power source, utilizing a diaphragm or piston that senses pressure fluctuations and automatically adjusts an internal valve to regulate fluid flow. This regulator is essential for biotechnology laboratories and clinical diagnostics where precise pressure control is critical in bioprocessing systems and molecular diagnostics instrumentation. Its reliable pressure modulation helps prevent over-pressurization, ensuring safety and operational stability in fluid delivery systems. Widely applicable in biomanufacturing environments, it supports high-precision fluid handling required in synthetic biology workflows and live-cell imaging setups. The device is suitable for a variety of laboratory and industrial applications requiring accurate pressure regulation within fluidic and pneumatic infrastructure.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
