What Affinite Instruments does

Affinité Instruments Inc., founded in 2015 and headquartered in Toronto, Canada, designs and manufactures portable Surface Plasmon Resonance (SPR) instruments for label-free binding analysis. Its platform is built on a patented lensless SPR architecture that eliminates conventional optics (lenses, prisms, precision alignment), enabling compact, lower-cost instruments that retain publication-quality kinetic data. The product portfolio spans the P4SPR 2.0 (ultra-compact 4-channel static SPR for rapid screening), the P4PRO (benchtop flow SPR with AffiPump for full kon/koff/KD kinetic characterization), AffiCoat proprietary zwitterionic peptide surface chemistry, disposable pre-characterized gold sensor chips and reagent kits, and the AffiLabs.core desktop software with embedded SPARQ in-device run quality diagnostics. The company sells directly to academic labs, biotech startups, pharma R&D groups, and biomanufacturing customers in 15+ countries, reaching 500+ researchers worldwide.

Revenue is generated primarily through one-time hardware sales of P4SPR and P4PRO instruments (quote-based pricing, no public list prices), a recurring consumables stream from single-use sensor chips and reagent kits, and a professional services tail via the Affibio SPR-as-a-service offering, which includes mobile SPR deployment to customer sites. Go-to-market is consultative and direct-to-customer, supported by 80+ peer-reviewed publications validating the platform, content marketing through application notes and a resource library, conference presence (e.g., PEGS 2025), and global lab visits. The company was built entirely on non-dilutive funding and remains privately held under founder control, with no institutional venture capital or PE investment disclosed. Key strategic partnerships include ongoing collaboration with Université de Montréal (origin of the technology) and the CERVO Brain Research Center for SPR-based AAV gene therapy quality control.

Revenue model

1. SPR Instruments: Sale of P4SPR 2.0 (static SPR) and P4PRO (benchtop flow SPR) instruments. Instruments are compact, laptop-powered where applicable, and sold directly via quote requests.
2. Sensors and Consumables: Disposable gold sensor chips with various surface chemistries (Carboxyl, CMD, AffiCoat, NTA, Streptavidin, Protein A/G, etc.) and reagent kits (amine coupling, NTA, SA, IgG capture, immobilization scouting). Sensors are pre-characterized, single-use to avoid carry-over.
3. Software (AffiLabs.core): Desktop software application included with instrument purchase. Software provides instrument control, data acquisition, kinetic analysis, and IQ/OQ validation. P4SPR 2.0 hardware upgrade available for existing owners with improved SNR and expanded surface sensor library access.
4. Affibio Service (SPR as a Service): Expert-run SPR experiments delivered to customers who need results without owning an instrument. Full characterization and scientific collaboration offered. Mobile SPR service brings the instrument to customer facilities for on-site testing.

Core offering

Affinité Instruments designs, manufactures, and sells patented lensless Surface Plasmon Resonance (SPR) instruments — the laptop-powered P4SPR 2.0 for static screening and the benchtop P4PRO with AffiPump for kinetic characterization — together with the AffiLabs.core software, SPARQ embedded run-quality diagnostics, proprietary AffiCoat surface chemistry, disposable gold sensor chips, reagent kits, and Affibio SPR-as-a-Service contract analysis. The integrated platform serves academic, biotech, pharma R&D, and biomanufacturing customers.

Product overview

Affinité Instruments offers a complete SPR (Surface Plasmon Resonance) platform centered on its patented lensless optical architecture. The product portfolio spans two complementary SPR instruments — the P4SPR 2.0 for portable static screening and the P4PRO with AffiPump for full kinetic characterization — supported by proprietary surface chemistries (Afficoat), disposable gold sensor chips and reagent kits, and a unified software ecosystem (AffiLabs.core). Embedded intelligence is provided by SPARQ (in-device run quality diagnostics) and extended by Sparq Bio (cloud AI platform, coming soon). SPR-as-a-service is available through Affibio. The platform is designed as an integrated ecosystem — instrument, microfluidics, consumables, software, and intelligence layer — co-engineered to work as one.

Products and services

• P4SPR 2.0 Ultra-compact, 4-channel, laptop-powered static Surface Plasmon Resonance instrument for rapid yes/no binding screening, concentration estimation in complex or crude media, and assay development; fM detection limit, 150 µL sample volume, and ≤10 min per cycle. Targeted at academic, biotech, and pharma research labs needing portable label-free binding analysis.
• P4PRO Benchtop 4-channel hybrid static/flow SPR system paired with AffiPump for full kinetic characterization (kon 10^3–10^7 M^−1s^−1, koff 10^−5–10^−1 s^−1, KD), with semi-automated injection and 5–100 µL flow injection volume. Targeted at researchers needing publishable kinetic data without core-facility access.
• AffiLabs.core Desktop application for P4SPR and P4PRO instrument control, data acquisition, kinetic and steady-state fitting, leak/bubble detection, ML-powered LED calibration, one-click Excel/CSV export, and IQ/OQ validation (12 automated IQ checks, 43 OQ tests across 6 suites). Targeted at P4SPR and P4PRO users needing compliant, software-driven experimental control and analysis.
• AffiPump Precision peristaltic flow-control accessory for the P4PRO providing stable, controlled flow (0.3–10,000 µL/min) for clean association and dissociation phases in kinetic SPR experiments. Targeted at P4PRO users needing precise kinetic measurements.
• AffiCoat surface chemistry Proprietary zwitterionic peptide self-assembled monolayer for gold SPR sensors that minimizes non-specific adsorption in serum, plasma, and cell lysate, enabling covalent capture-molecule immobilization while preserving enzyme activity.
