Proven impact across leading catalysis research labs

University of Central Florida’s Hydrogen Fuel Cell Laboratories

Uses Harrick Scientific’s diffuse reflectance accessories in conjunction with a Perkin-Elmer Spectrum 100 FTIR system to study hydrogen production, storage, and material properties. This integration supports advanced research into alternative fuels and high-temperature reactions

University of Utah’s Nanointerface Engineering Group

Employs a Harrick Praying Mantis HVC reaction chamber along with a Thermo Scientific FT-IR system and Shimadzu spectrophotometers. This setup facilitates precise temperature-controlled reactions in research on material surfaces and nanoscale interfaces.

San Diego State University’s Gu Lab

Integrates Harrick’s VariGATR Grazing Angle ATR accessory with their ThermoFisher Nicolet iS50 FTIR spectrometer, supporting infrared spectroscopy analysis of various materials. This setup is instrumental in their work on chemical imaging and spectroscopic analysis of complex compounds.
