Cryogenic Grinder - Liquid Nitrogen Freezer Mill - 0.1-100 g - 5-15 Hz Impact

The Master Science Cryogenic Grinder freezes samples in liquid nitrogen and breaks them with electromagnetic impact, making it possible to grind materials that are too tough, elastic or heat-sensitive to mill at room temperature. A typical grinding cycle takes about 2 minutes.

Typical samples include polymers, rubber, textiles, grains, hair, nails, skin, bone and muscle tissue, as well as food, mineral, drug and plant material for DNA and biochemical work.

Common Laboratory Problems and How This Grinder Helps

How the Master Science Cryogenic Grinder handles difficult samples:

• Elastic samples smear instead of breaking: cryogenic freezing makes them brittle.
• Volatile or heat-sensitive compounds lost: grinding stays at liquid nitrogen temperature.
• Running out of nitrogen mid-run: level sensor and auto top-up.
• Many small samples: 12 × 3 mL jars per batch.
