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.

Helping Scientists Scale & Succeed
"We used Excedr when it was time for us to make a large capital equipment purchase and the whole leasing process was smooth, quick, and seamless.
As a busy start-up CEO, I am always aware of how important it is to keep our science progressing while on a tight budget.
Working with Excedr made it possible for us to accelerate our scientific discovery pipeline without a large outlay of capital."
Jessica Grossman
CEO, IgGenix
"Building a biotech is a lot of work. Excedr has been a dynamite partner in making that scaling happen.
They were a great partner when scaling Distributed Bio from an 8 member 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."
Jacob Glanville
CEO & President, Centivax
"Securing top-tier lab equipment while managing cash flow is a constant challenge. Excedr has been an invaluable partner in helping KiraGen Bio access the high-quality instrumentation we need without the heavy upfront costs.
Their flexible leasing options and outstanding support allow us to focus on advancing our research rather than worrying about equipment procurement and maintenance. For any biotech startup looking to scale efficiently, I can’t recommend Excedr enough."
Aaron Edwards
Co-Founder & CEO, KiraGen Bio
"Excedr helped us to finance a BLI system about a year ago. Sylvia did an excellent job at helping us to understand our options, since our company was new to equipment financing.
The leasing process was fast and easy when compared with self-funding our purchase, plus the speed and ease with which Excedr onboarded us freed up our team’s time to focus on research and grant management.

General Counsel & VP Operations, Zab Bio
“The lease of our Zeiss EVO10 electron microscope has significantly impacted our outside analysis costs, realizing a significant savings in the 1st year.
Having the instrument on-site has greatly improved our response times to field issues and fabrication challenges, while improving our Engineering and Production Teams' overall understanding of our product lines."
