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.

Lined Steel Grinding Jars
Lined Steel Grinding Jars

Features:

  • All sizes have quick-change snap-in liners This feature is especially 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.
    Note: Cover liners are not snap-in; a different cover is needed for use with each liner

  • 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

Model 612A (Low Ash), 612B (Buna-N), 612E (EPDM),
