Product principle

Vertical oscillation, high-frequency reciprocating motion of the oscillation system, causes the frozen sample in the grinding tube to collide with the grinding ball, and the grinding shear force and impact force generated by it completely breaks the tissue.


Technical parameters

1. Vertical oscillation;

2. Oscillation frequency: 500-1800 times/min;

3. Grinding time: 10 seconds to 99 minutes, which can be set by users;

4. Number of grinding machines: 2;

5. Grinding ball material: stainless steel, chrome steel, zirconia, tungsten carbide, quartz sand;

6. Grinding ball diameter: 0.5-30mm;

7. Fixture travel 3.7cm (vertical);

8. Power: 400W;

9. The door opening and power-off function ensures safety;

10. Power supply: 3-hole socket, 220-240V, 50Hz;

11. Weight: 62kg;

12. Size: 38cm (W) × 46cm(D) × 50cm(H)。



1. One host;

2. Adapter:

2.1  One pair of 8-hole 50ml adapter;

2.2  15-hole 15ml adapter 1 pair (optional);

2.3  100ml stainless steel grinding tank 1 pair (optional);

2.4  200ml stainless steel grinding tank 1 pair (optional);

2.5  1 pair of 300ml nylon cans (optional);

3. One set of alloy fixture;

4. A set of grinding balls.

Operation steps

1. Add the processed sample and grinding ball into the centrifuge tube in turn;

2. Put the centrifuge tube with the sample into the adapter;

3. Put the adapter with sample into liquid nitrogen for freezing for several minutes;

4. Place the frozen sample and adapter in the middle of the fixture and adjust the position;

5. Place the fixture on the sample table, position the positioning slot, tighten the vertical positioning knob, and return the safety lock;

6. Close the safety door of the machine;

7. Set vibration frequency and time;

8. Start the machine and execute the crushing process;

9. Wait for the machine to completely stop vibration, shut down, open the safety door, and take out the sample;

10. Return the instrument.



1. The instrument should be placed in a dry and ventilated environment for use;

2. The sample is symmetrically distributed in the sample holder to ensure the balance of the sample holder;

3. Before closing the safety door, it is necessary to confirm that the clamp has been completely fixed without looseness;

4. When setting the oscillation frequency, it shall not exceed the maximum range of 1800 times/min;

5. When freezing the sample, pay attention to prevent liquid nitrogen from splashing out, causing frostbite.
