Heat or cool the jars
Thermal plates provide a path for heat transfer while milling. Their operating range extends from −100 to +100 °C, depending on the complete setup.
TEMPERATURE AS A PROCESS VARIABLE
MM 500 control.
Temperature, considered.
Combine high-energy dry, wet or cryogenic grinding with monitored heating and cooling. Thermal plates transfer heat to or from the jars, helping tailor preparation to temperature-sensitive samples and controlled research methods.
Configuration examples. Accessories may be optional.
FEED SIZE*≤ 10 mm
FINAL FINENESS*~ 0.1 µm
FREQUENCY3–30 Hz
SAMPLE QUANTITY*2 × 45 ml
THE MODEL IN FOCUS
Monitored heating, cooling & temperature-sensitive methods
Monitor the process
The display tracks thermal-plate temperature. Optional GrindControl measures temperature and pressure inside a compatible jar.
Two larger sample positions
Use jars up to 125 ml nominal volume, with useful sample quantities up to 45 ml each and frequencies up to 30 Hz.
HOW IT WORKS
Oscillation.
Impact. Mixing.
Grinding jars oscillate in a horizontal position. The balls’ inertia drives them into the sample at the rounded jar ends. Impact and friction reduce the material while the motion mixes it.
Match ball size, number, jar material, filling level, frequency and time to the sample. Use smaller beads for compatible bead-beating methods; use a validated liquid and dispersion method for wet grinding.
Feed size, final fineness and useful sample quantity depend on the material, tools and operating conditions. Jar volume is not the sample filling volume. The finest result and largest feed or batch are not simultaneous guarantees.
METHOD & CONFIGURATION
Choose the temperature setup with the method.
The mill requires an external tempering device for temperature regulation. Use liquid nitrogen with cryoPad for controlled low-temperature operation, or a compatible circulating thermal fluid for heating and cooling. The displayed thermal-plate temperature is not a direct measurement of sample temperature.
- Thermal-plate range: −100 to +100 °C depending on configuration
- LN₂ with cryoPad: −100 to 0 °C selectable setpoints
- Frequency range: 3–30 Hz; two grinding stations
BUILD THE RIGHT SETUP
The tools make the method.
Select jars, balls and supporting accessories around your material and analysis. Confirm the complete configuration and what is included in the quotation.
cryoPad & nitrogen supply
Liquid-nitrogen operation requires the optional cryoPad and a suitable nitrogen supply. It regulates the thermal plates from −100 to 0 °C in 10-degree setpoint steps.
External thermal-fluid supply
Connect a compatible chiller, cryostat or other specified tempering source for heating or cooling. Achievable conditions depend on the fluid, source and grinding heat load.
Jars & application tools
Compatible jar materials include hardened steel, stainless steel, tungsten carbide and zirconium oxide. Ask about aeration lids, GrindControl, multi-cavity jars and vial adapters.
