Vertical ATR with Interchangeable Crystals for FTIR Spectroscopy

Research grade VAOI vertical ATR (VAOI = variable angle of incidence). 50% Energy throughput continuously variable angle of incidence (25° to 75°). See-through purge cover for ease of consistent placement of sample holder. Interchangeable ATR crystals; ZnSe, Si, Ge, KRS-5 crystals available with 30°, 45°, or 60° angles of incidence. Sample pressure controllable via optional torque hex wrench. Snug seal in Nicolet FTIR compartments for simple purging.
