SPR System Leasing for Labs

Lease the SPR system that fits your workflow. Analyze biomolecular interactions in real time—without tying up your budget.

What Is Surface Plasmon Resonance?

SPR is an optical detection technique that measures changes in refractive index to monitor biomolecular interactions in real time—without labels. It's widely used for analyzing binding kinetics, affinities, and concentrations in drug discovery, immunology, and protein characterization. This label-free method enables high-sensitivity measurements of interaction dynamics with minimal sample prep.

Why Lease an SPR System?

SPR delivers high-resolution, real-time data for protein-protein, protein-small molecule, and antibody-antigen interactions. But acquiring an SPR system—especially one with multiple channels, high sensitivity, and advanced software—requires significant capital.

Leasing helps you implement this critical technology without the burden of upfront costs. It’s an ideal solution for biotech R&D, CROs running binding studies, and pharma teams validating hits or optimizing lead candidates. With leasing, you can scale access to precision interaction analysis without compromising cash flow or delaying timelines.

Where Leasing an SPR System Adds Value

Analyzing biomolecular interactions—such as binding kinetics, affinity, and specificity—is critical for drug discovery, therapeutic screening, and diagnostic development. However, advanced platforms offering real-time kinetics, high sensitivity, and multiplexing capabilities can require substantial upfront investment.

Leasing can be a smart choice when:

  • Validating lead candidates or screening therapeutic binders—Quickly access high-sensitivity analysis without upfront financial barriers.
  • Needing flexible throughput or multi-channel kinetic analysis—Adapt instrument capacity and capabilities as your assay demands evolve.
  • Prioritizing capital for pipeline advancement or downstream assays—Preserve financial flexibility while still acquiring critical interaction data.

Whether quantifying affinity or mapping epitopes, leasing biomolecular analyzers supports deeper insights—without straining your resources.

"Excedr's lease structure helped us extend our cash runway, forecast our projects with greater accuracy, and track and manage upcoming expenses more effectively, putting us in a stronger position for our next venture round."

Shawn Gahr

COO & Co-Founder, Novoron

"Building a biotech is tough, and Excedr has been a dynamite partner in scaling. They supported Distributed Bio’s growth from an 8-person lab team to 35 members by the time of acquisition.

When I started Centivax, Jon was one of the first people I called. I recommend them for any biotech startup."
