Vibration Isolation Case Studies

DVIA-ULFB700 installation report (serial 260202R1-5) for a Thermo Fisher Scientific Axia SEM at End User Shanghai Opotong Instruments Co., Ltd. in Shanghai, China. Measured with the equipment turned on/IDLE, the floor read VC-B vertically, VC-E left-to-right and VC-D front-to-back, while the DVIA-ULFB700 platform reached VC-F, VC-G and VC-G on the same axes. Published figures: the vibration specification page from the equipment pre-installation manual, per-axis VC Curves, Autospectrum and Transmissibility captured from the UI program, and an equipment photo.

DVIA-ULF1000 (S/N 260415R5) tuning and vibration measurement at ASM Hwaseong Plant Building 1, 4F laboratory for a ZEISS FE-SEM GeminiSEM 560; tuning on May 11, 2026; report dated May 14, 2026. Equipment turned on/IDLE; measurement summary with floor and platform RMS per the report; vertical, left-to-right, and front-to-back VC curves, autospectra, and transmissibility; on-site installation photo. Decorative banner and reference EMF graphic omitted — Reference uses the standard VC markdown table.

Installation report for Thermo Fisher Scientific SEM (Helios model) on DVIA-ULF1000 (S/N 260320R1) at Beijing for Citic Metal; tuning 13 May 2026. Prepared for and End User both list Citic Metal—the public page omits a duplicate Prepared for block. Vibration specification is UI capture only; Measurement Summary uses the report’s eight-column RMS and PASS/FAIL layout. Publishes VC curves, Autospectrum, and Transmissibility for vertical, left-to-right, and front-to-back axes plus equipment photo; Reference is the standard Generic Vibration Criteria markdown table only (Word EMF omitted). Decorative header logo strip before the title block is not published.
