EOS Srl

What EOS Srl does

EOS Srl, doing business as EOS Instruments, is an Italian private limited company founded in 2014 in Milan that designs, manufactures, and services single-particle optical analysers. The company's core technology is the patented SPES (Single Particle Extinction and Scattering) platform, which measures individual particles in continuous flow and retrieves up to three independent optical parameters per particle (extinction, forward scattering, and side scattering at 90 degrees) to enable classification by both size and effective refractive index in heterogeneous biological, industrial, and environmental fluids. This calibration-free, particle-model-free approach is delivered through the Classizer™ product family: Classizer ONE for liquids, Classizer AIR for aerosols, and Classizer NANO and Classizer HOLO for nano-scale and holographic analysis, complemented by LMS, LAS, and LAD automation accessories, Classizer User Software with PCA and CFA add-ons, and consumables.

The business operates a hybrid revenue model combining hardware sales (Classizer instruments and accessories), professional services (contract analysis and custom hardware/software solutions for specialised R&D and QC workflows), and recurring software licence subscriptions for the PCA and CFA add-ons. Go-to-market is enterprise field sales supplemented by exclusive regional distributors in Italy (Optoprim), Germany (Quantum Design Europe), and UK/Ireland (Analytik), with active participation in industry trade shows (Analytica, SETAC, Making Cosmetics, MECSPE) and a content-driven motion backed by peer-reviewed publications and a 20+ application note library. Pricing is quote-based with multi-year contract cadence, and the customer base spans academic research groups (e.g., University of Bern, Milano-Bicocca, FAU Erlangen-Nürnberg) and industrial accounts (altona Diagnostics, Agfa-Gevaert, Industrie De Nora) across pharmaceuticals, cosmetics, pigments and inks, food and beverage, abrasives, polymers, and environmental sciences.

• Malvern Panalytical: Global leader in particle characterization instruments (Mastersizer, Zetasizer). Directly competes with EOS in laser diffraction and DLS-based particle sizing, and is the most established incumbent in EOS's core market for pharma, materials, and environmental particle analysis.
• Beckman Coulter Life Sciences: Offers particle sizing and counting instruments (e.g., Multisizer, Vi-CELL) widely used in biopharma and life science QC. Comparable to EOS in serving pharma/biotech QC use cases, particularly for cell and particle concentration measurements.
• Microtrac MRB: Manufactures laser diffraction, DLS, and image analysis particle analyzers (Sync, S3500, Bluewave). Direct peer in particle size distribution measurement, particularly for submicron and complex dispersions where EOS's SPES technology competes.
