Molecular Sieve desiccant bags

WHS-B-MS4006

  • Molecular Sieve is ideal for RH <5%
  • Protects against moisture ingress during shipping and transit
  • Suitable for long-term, controlled-environment storage
  • Manufactured from low-dust, sulfur-free materials compliant with ISO Class 5+ cleanroom standards

These high-performance Molecular Sieve moisture adsorbents are specifically engineered to safeguard semiconductor wafers, microchips, and sensitive electronic components throughout packaging, storage, and transportation.

WHS® Desiccant Bags effectively lower relative humidity (RH) within sealed packaging, helping to prevent oxidation, corrosion, and material degradation. Designed to meet cleanroom and semiconductor industry requirements, these desiccants support reliable contamination control and product integrity.

WHS® Desiccant Bags are available in a standard 6 g format. Custom weights, sizes, and configurations can be provided upon request. Please contact us for additional details.
