Durable 12mm polarographic dissolved oxygen sensor with autoclavable 316L stainless steel body for bioprocess monitoring.
The Broadley-James D145-B220-PT-D9 is a rugged and versatile *polarographic dissolved oxygen sensor* designed for precise DO measurement in benchtop bioprocess vessels. It features a 12 mm diameter body constructed from 316L stainless steel with RA32 finish, ensuring exceptional durability and compliance with FDA standards. The sensor is equipped with a semi-permeable Silicon/Teflon composite membrane, reinforced with stainless steel, enhancing its chemical resistance and longevity in cell culture and biomanufacturing environments.
This sensor incorporates a right-angled Pg13.5 connector, minimizing cable fatigue and improving extraction grip, ideal for integration in compact setups like spinner flasks and small-volume bioreactors. The design enables direct fitting into standard 12 mm multipurpose ports via compression fittings or threaded connections.
Engineered for demanding bioprocess monitoring, the sensor supports autoclave and steam sterilization, making it suitable for high-temperature sterilization cycles common in molecular diagnostics and synthetic biology workflows. Internal EPDM O-rings ensure a secure, leak-proof assembly during extended operation.
Key technical specifications include:
Widely used in biotechnology research, molecular diagnostics, and biopharmaceutical production pipelines, this sensor is essential for real-time dissolved oxygen monitoring integral to live-cell imaging, fermentation control, and synthetic biology research applications. Its autoclavable stainless steel construction and advanced membrane technology make it a reliable choice for high-precision oxygen measurements in controlled laboratory environments.
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.
