This is a small-scale, high-precision size. It's used for applications where the sample material is:
- Extremely Valuable or Rare: e.g., experimental pharmaceuticals, novel catalyst materials, rare geological samples, or precious metals.
- Required in Very Small Quantities: e.g., for research where only a few grams of nano-powder are needed for analysis (like X-ray diffraction, electron microscopy).
- Experimental Trial Runs: Testing a new milling process or material combination before scaling up to a 500ml jar.
As with the 500ml jar, this specifies the highest grade of zirconia.
Benefits: Exceptional wear resistance, extreme hardness, superb fracture toughness, and excellent chemical inertness.
Importance for Small Jars: In a small jar, the surface-area-to-volume ratio is higher, making the purity and non-reactivity of the jar material even more critical to prevent contamination.
D50: The internal diameter is 50 mm. This is a compact size, suitable for smaller planetary mills or multiple jars on a single mill disc.
H60: The internal height is 60 mm.
Why this matters: This small, specific form factor is essential for fitting the mounting systems of compatible mills. Using an incorrectly sized jar is impossible and unsafe.
The description says "Jars" (plural). It is common to purchase these small jars in a set (e.g., 2 or 4 jars) to maximize the use of a milling run. You can process multiple different materials or formulations simultaneously.
