About

Dimer Instruments is a Santa Barbara, California company building analytical instrumentation for the biopharmaceutical industry. Founded in 2023 by Dr. Stephen Minne and Dr. Michael Larkin, both veterans of light-scattering instrument maker Wyatt Technology, it applies multi-angle and dynamic light scattering (MALS and DLS) and biophysical characterization to drug discovery, formulation, and manufacturing. Its instruments measure protein stability, molecular binding interactions, and protein expression, including process analytical technology (PAT) applications for real-time monitoring during manufacturing.

Founded by light-scattering instrumentation veterans, the company targets real-time, in-process biophysical measurement (PAT) rather than offline benchtop-only analysis, aiming to move protein characterization onto the manufacturing line.
