These ceramic jar bodies have been formulated to provide about 4 times the wear rate of our competitor’s porcelain jars. Lower silica content cuts silica contamination by more than half. High-strength, impact-resistant composition minimizes chipping and breakage.

Features

  • Positive lid locking bar and hand well for quick, easy opening and closing
  • Precision ground cover and gasket seat assure leak-proof fit
  • Wide mouths for fast emptying, cleaning, loading
  • Gaskets are oil, solvent and chemical-resistant Neoprene rubber
  • Inside surfaces are unglazed

Features

  • All sizes have quick-change snap-in liners This feature isespecially significant when varied materials are milled and cross contamination must be avoided
  • Using a separate liner for each material protects the product, saves clean-up time, reduces number of jars required
  • Jars are carbon steel
  • Recommended where silica contamination must be held to an absolute minimum
  • Buna-N, EPDM, Low-Ash rubber, Neoprene, and Polyurethane liners are available

 Note: Cover liners are not snap-in; a different cover is needed for use with each liner
