Desiccant > VAPLOK™ Desiccants

Advantek VAPLOK™ Desiccants protect moisture-sensitive devices by absorbing airborne moisture particles which may be present inside a moisture barrier bag after vacuum packaging.

  • Meets EIA Std. 583 and MIL-D-3464, Type I and II.
  • Use with Advantek Humidity Indicator cards and DRYLOK® Moisture Barrier Bags for superior protection
  • Desiccant material can be either Clay or Silica Gel



VAPLOK™ Desiccants are made of Montmorillonite (bentonite) Clay or Silica Gel desiccant material packaged in printed, non-dusting, sulphur-free Tyvek® substrates.


Advantek VAPLOK™ Desiccants are available in several formats designed for small and large applications. Bag sizes vary from 1/6 unit packs to 4 unit packs. A unit of desiccant (33 grams) refers to its drying capacity, not its volume, and is the amount of desiccant which will absorb at least 3 grams of water vapor at 20% relative humidity and at least 6 grams of water vapor at 40% RH at 77F (25C) per JEDEC standard. The product is shipped in airtight packaging to prevent exposure to moisture.

Shelf Life and Storage

We recommend that VAPLOK™ desiccant products be used within 24 months of manufacture. Store this product in its original packaging in a climate-controlled environment where temperature ranges from 20°C +/- 16°C (68°F +/- 61°F) and relative humidity is 50% +/- 30%. Exceeding these recommended storage conditions could result in inconsistent product performance.
