Cell Lab stainless steel roller mill jars are ideal for mechanical alloying, powder homogenisation, and sample preparation involving medium-hard or brittle materials. They are widely used in:
Battery material research (cathode/anode powder mixing)
Metal and alloy powder production
Ceramic and composite material milling
Geological and metallurgical sample preparation
Research institutes, universities, and R&D laboratories requiring robust, contamination-resistant milling containers
Q1: How do I choose between 304 and 316 stainless steel?
A: Grade 304 suits general laboratory use; Grade 316 offers higher corrosion resistance and is preferred for samples exposed to acids, chlorides, or moisture.
Q2: Can these jars be used for wet milling?
A: Yes. Each jar includes a silicone sealing gasket and clamping system ensuring leak-free wet milling performance.
Q3: Are the jars compatible with all roller mill systems?
A: The jars follow standard roller dimensions and are compatible with most bench-top and floor-type roller mills. Always check the roller spacing before operation.
Q4: What grinding media should I use?
A: Stainless steel balls (304 / 316) are recommended to avoid cross-contamination. Other media types can be used if hardness compatibility is confirmed.
Q5: How do I maintain the jar’s lifespan?
A: Avoid excessive impact energy, clean promptly after use, and store dry. Periodically inspect sealing gaskets and replace if signs of wear or deformation appear.
