High-Access SEM Acoustic Enclosures

Technological advancements in electron microscopy make operating in a quiet and stable environment necessary. Herzan’s latest acoustic enclosure for electron microscopes ensures maximum protection from disruptive acoustic noise originating from pumps, chillers, and other loud laboratory equipment.

Every SEM acoustic enclosure can be customized to the electron microscope’s specific requirements and research needs, ensuring the researcher receives optimal results from their microscope.

Product Highlights

  • Designed for EMs: modular/paneled design for maximum performance and utility.
  • Leading Performance for Acoustically Sensitive EMs: multiple layers of sound dampening material for broad frequency acoustic isolation.
  • Accessibility for Ease-of-Use: multiple cable access ports and double-access doors allow for uncompromised access to the electron microscope at all times.
  • Mobile and Removable: detachable caster jacks allow for high portability and accessibility when needed.

The multi-layered, variable density materials lining the walls of the High-Access SEM Enclosure allow for high-performance acoustic isolation across a broad frequency spectrum.

NOTE: performance may vary depending on the size and unique features of the researcher’s room and any customizations made to the SEM Enclosure

Performance Highlights

  • 36 dB of sound loss at 200 Hz
  • 37 dB of sound loss at 500 Hz
  • 36 dB of sound loss at 1,000 Hz
  • 36 dB of sound loss at 1,500 Hz
  • 39 dB of sound loss at 2,000 Hz


Every enclosures acoustic lining can be tailored to specific noise frequencies measured within the environment. Share your site survey with a Herzan engineer today to optimize the enclosure for your lab.
