The Organic Impurities test is a widely used, simple procedure to determine presence of organic compounds in fine aggregates. Gilson offers a complete HM-137 Organic Impurities Test Set or individual set components for your convenience.

Samples are shaken in a special graduated bottle with a 3% sodium hydroxide solution then allowed to stand for 24 hours. If the resulting color of the liquid above the test sample is darker than a reference standard color, organic compounds may be present and further testing should be done before approval.

The set includes six graduated 240ml (8oz) colorless glass Impurities Test Bottles, a 1lb (454g) bottle of standard grade Sodium Hydroxide (NaOH) Pellets and a Color Reference Chart. The Color Reference Chart has been upgraded to meet the latest ASTM revisions, and has five permanent reference colors mounted in a durable protective plastic case. The sodium hydroxide pellets make enough 3% solution to perform over 150 tests. For strict compliance to ASTM and AASHTO Standards, order HM-818 Reagent Grade Sodium Hydroxide Pellets.

For areas with shipping restrictions, the HM-137F includes all items listed except the sodium hydroxide reagent. The HM-817 Test Bottles are graduated in oz and ml and have watertight screw-on caps.

Features:

  • Sodium hydroxide pellets supply enough 3% solution for over 150 tests
  • Upgraded five-color Color Reference Chart meets latest ASTM revisions
  • Sodium Hydroxide Pellets available in standard or reagent grade formulations
