Product description

Refurbished D540-B320 OxyProbe II sensor offers fast, accurate DO measurement with autoclavable 316L stainless steel design.

The Broadley-James D540-B320 OxyProbe II is a high-precision dissolved oxygen sensor engineered for laboratory and bioprocessing applications requiring reliable and rapid oxygen measurement. Featuring an autoclavable and sterilizable 316L stainless steel cage with a polished N5/Ra15µ surface finish, the sensor minimizes microorganism adherence essential for molecular diagnostics and synthetic biology research.

Key technical specifications include:

12 mm probe diameter suitable for benchtop and inline bioprocess monitoring
Unique expandable inner silicone bladder membrane designed to prevent membrane distention under high pressure, reducing maintenance risks during biopharmaceutical production
Quick, on-site membrane replacement within two minutes, enhancing operational uptime in critical cell culture oxygen monitoring workflows
Gold-plated contacts housed in a glass insulator provide superior signal isolation via the D9 straight cable connector, ensuring accuracy and signal stability in fluorescence analysis and live-cell imaging environments
Wetted O-rings FDA and USP VI compliant, aligned with stringent clinical diagnostics standards

This sensor is widely used in biotechnology laboratories and research environments where sterility and precise dissolved oxygen measurement are vital for gene editing and bioprocess control. The OxyProbe II’s robust design and rapid response time make it indispensable in both molecular biology and biomanufacturing settings, supporting reproducible data generation and quality control. Please note, the product is refurbished and does not include the computer or software interface.

€134 sits below most gas analysers here. The middle half of the 55 with a price runs from €179 to €1,411.

Why Questpair exists

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.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
