MJ14 2L Air-tight Milling Jar for MTI Lab Roller with Corundum, Polyurethane, or Nylon Construction
MJ14 is designed to provide a sealed environment for grinding a variety of metals and non-metals using the MTI MSK-SFM-14 lab roller mill. This 2-liter jar is engineered to prevent air and water ingress, ensuring sample integrity during milling processes that require contamination control and moisture exclusion.
The jar is available in three material options—corundum, polyurethane, and nylon—each suited for different milling applications and sample compatibilities. The air-tight design supports efficient grinding by maintaining a controlled atmosphere inside the jar. The milling media included varies by jar material: alumina balls accompany the corundum jar, while yttria-stabilized zirconia (YSZ) balls are supplied with polyurethane and nylon jars. Users should pre-mill the empty jar with the milling media to minimize surface contamination before processing samples.

Typical Applications
Ideal for laboratory-scale grinding and mixing of metals and non-metallic materials where air and moisture exclusion is critical. Suitable for sample preparation in materials science, chemistry, and related research fields requiring contamination-free milling.
Configuration & Operating Notes
Users must select the jar material according to their milling needs. The jar comes with corresponding milling balls but additional milling media can be purchased separately. It is strongly advised to mill the empty jar with the milling balls before introducing samples to reduce surface contamination. The jar is compatible with the MSK-SFM-14 lab roller mill. Proper sealing ensures air-tight and water-tight operation during milling cycles.
