Product description

High-performance sterilizable dissolved oxygen sensor with silicone bladder in stainless cage and D9 connector.

The Broadley-James D540-B320-PT-D9 OxyProbe II is a high-precision dissolved oxygen sensor optimized for laboratory and bioprocessing applications. Manufactured in 2011, this refurbished turnkey unit features:

  • Membrane Design: A 25mm expandable inner silicone bladder secured inside a durable 316L stainless steel cage, enabling steam sterilization and autoclaving without compromising sensor integrity.
  • Connector: Equipped with a D9 connector housing hermetically sealed gold-plated contacts for enhanced signal isolation and reliable transmission essential in molecular diagnostics and biomanufacturing workflows.
  • Hygienic Surface: The sensor body includes a polished N5 surface finish that resists microorganism adhesion, critical for aseptic operations in synthetic biology and cell culture monitoring.
  • Modular Maintenance: Designed for quick field replacement of membrane and sensor inner components, reducing downtime during bioprocess monitoring or clinical diagnostics procedures.
  • Compliance: Constructed from FDA-positive listed materials and meets USP Class VI standards, ensuring biocompatibility in live-cell imaging and biotechnology research environments.
  • Specifications: Sensor diameter of 12mm; weight approximately 1.09 kg; fully autoclavable for seamless integration into sterile bioprocess equipment.

Widely adopted in biotechnology, molecular biology, and biomedical engineering applications, this oxygen sensor is essential for accurate dissolved oxygen measurement in fermentation, bioreactor monitoring, and molecular cloning workflows. Its robust design and sterilization compatibility make it ideal for high-demand environments requiring consistent oxygen monitoring and control.

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?

Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
