Applied Photophysics

What Applied Photophysics does

Applied Photophysics Limited is a UK-headquartered manufacturer of high-performance biophysical characterization instruments used in biopharmaceutical development, academic research, and contract research. Its three product lines are the Chirascan family of circular dichroism (CD) spectrometers (VX, V100, and Q100 models differentiated by detector type and automation), the SX20 stopped-flow spectrometer for millisecond kinetic studies, and the SUPR-DSF/SUPR-CM microplate-based differential scanning fluorimetry platforms commercialized via the Protein Stable joint venture with Fluorescence Innovations Inc. Underlying technology includes a proprietary double Czerny-Turner prism monochromator with crystalline quartz prisms, large-area avalanche photodiode (LAAPD) detectors, photoelastic modulators, and HOS Comparison software that performs weighted spectral difference analysis validated against FDA biosimilar guidance. The company sells globally through direct offices in Leatherhead (UK), Charlotte, NC (US), and Shanghai (China), supported by a regional distributor network across Europe, the Americas, and Asia-Pacific.

The business model rests on a one-time capital purchase for instruments (Chirascan, SX20, SUPR-DSF), supplemented by recurring revenue streams that are strategically enforced: a mandatory annual Support Plan is required to preserve the five-year warranty, generating managed-services revenue from preventive maintenance, calibration, priority technical support, and spare parts; Pro-Data SX and Pro-K software licenses add further licensing revenue; and consumables (xenon lamps, PEEK flow circuits, quartz cells, syringes) and training services round out the revenue stack. Pricing is quote-based and not publicly disclosed, consistent with enterprise capital sales cycles.

Applied Photophysics was founded circa 1970 in Leatherhead, Surrey, and operated as an independent private company for over 50 years before being acquired by Nicoya Lifesciences (Canada) in May 2025, at which point it became a wholly-owned subsidiary and Nicoya's European hub. The company is led by CEO Tim Flanagan and holds ISO 9001:2015, ISO 14001:2015, TUV SUD NRTL, and CE Mark certifications. No venture capital or private equity funding history was identified in available sources.

Core offering

Applied Photophysics manufactures and sells scientific instrumentation for the biophysical characterization of biomolecules. Its core product lines are Chirascan circular dichroism (CD) spectrometers (VX, V100, Q100) for studying protein higher-order structure, the SX20 stopped-flow spectrometer for kinetic studies of fast biochemical reactions, and the SUPR-DSF microplate-based differential scanning fluorimetry platform for high-throughput protein stability screening. The company also offers service plans, spare parts, consumables, software licenses, and training to support installed instruments.

Product overview

Applied Photophysics is a provider of biophysical characterization instruments comprising three main product lines: Chirascan circular dichroism systems (including Chirascan VX, V100, and Q100 variants for different sensitivity and automation requirements), SX20 stopped-flow spectrometers for fast reaction kinetics, and SUPR-DSF plate-based differential scanning fluorimetry for protein stability screening. The products are sold alongside specialized accessories including CCD fluorometers, titrators, and temperature control units. Through a joint venture with Fluorescence Innovations Inc (operating as Protein Stable), the company also offers SUPR-CM chemical melt instruments. Applied Photophysics was acquired by Nicoya Lifesciences in May 2025.
