Vertical oscillation is currently an efficient method for sample grinding, offering significant advantages in terms of efficiency, homogeneity, and contamination prevention:

1. High grinding efficiency : High-frequency vertical acceleration imparts greater impact kinetic energy to the grinding beads, enabling rapid fragmentation of hard tissues in only one-third to one-half the time required by horizontal oscillation;

2. The results exhibit good uniformity. : All samples are subjected to uniform stress, with minimal variation between wells or tubes, ensuring high experimental reproducibility and completely eliminating inter‑individual variability associated with manual grinding.

3. Prevention of cross-contamination : The sample is completely sealed within the tube/plate, preventing aerosol dispersion and avoiding cross-contamination between samples, thereby complying with biosafety requirements;

4. More diverse modes : Supports wet grinding, dry grinding, and low-temperature grinding modes, accommodating samples of various properties.

It features a wide parameter adjustment range and fast acceleration/deceleration response, allowing flexible optimization of the most suitable grinding conditions based on the sample type.

1. Homogenization speed: continuously adjustable from 0 to 70 Hz; low speeds are suitable for soft samples, while high speeds are ideal for hard samples.

2. Timing range: Precisely adjustable from 0 to 99 seconds, accommodating varying degrees of crushing and particle size requirements.

3. Acceleration and deceleration performance: Both acceleration and deceleration can reach the target speed within 2 seconds, with smooth operation and no sample splashing.

4. Cycling Mode: Supports an intermittent “grinding–stop” cycling mode, with adjustable dwell time and number of cycles, enabling effective control of sample temperature rise.

1. Operating procedure: Immerse the alloy module in liquid nitrogen for 5 seconds to quickly establish a cryogenic grinding environment; when used with the intermittent mode, low temperatures can be maintained for extended periods.

2. Core function: Minimizes nucleic acid degradation and protein denaturation caused by frictional heat during the grinding process, thereby ensuring the integrity of extracted nucleic acids or proteins.

3. Applicable scenarios: Grinding of temperature-sensitive biological samples, such as RNA extraction, active protein isolation, and enzyme sample preparation.

Built-in program control system, balancing ease of operation with experimental flexibility:

1. Preset Programs: The device features 10 built-in preset program controllers, allowing quick access to the appropriate parameters for different sample types without the need for repeated configuration.

2. Custom Programming: Supports free configuration of parameters such as grinding time, vibration frequency, and intermittent mode; saved settings can be recalled directly.

3. Ease of Use: Parameter settings are intuitive, requiring no complex training; even novice laboratory personnel can quickly become proficient.

1. Worktop requirements: Place the instrument on a level, stable laboratory workbench and adjust its horizontal alignment using the leveling mechanism at the base.

2. Environmental requirements: Place in a dry, well-ventilated indoor location; avoid moisture, corrosive gases, and strong magnetic fields; keep away from heat sources and direct sunlight.

3. First-time use: After unpacking, remove the internal transport securing devices, verify that the chamber is free of foreign objects, and run the equipment under no-load conditions to confirm there are no unusual noises or mechanical jams before loading samples.

4. Power Requirements: Use a properly grounded power supply and avoid sharing the same outlet with high‑power equipment.

The operating noise is less than 55 dB, placing it in the low-noise category and making it suitable for standard laboratory environments.

1. Imported linear bearings: Utilize high-quality imported linear bearings with a low coefficient of friction, ensuring smooth operation, excellent wear resistance, and reduced mechanical noise.

2. Internal Cavity Soundproofing Design: The instrument’s internal cavity is lined with sound-absorbing foam, effectively absorbing and blocking operational noise.

3. Optimized motion control: Independent control of the motion mechanism ensures smooth acceleration and deceleration, minimal impact noise, and stable operation.

4. Noise Level: Under full-load operation, the noise is less than 55 dB, ensuring no acoustic disturbance to the laboratory environment.

1. Grinding bead materials: Supports alloy steel beads, chrome steel beads, zirconia beads, tungsten carbide beads, quartz sand beads, and more; selection can be made based on sample hardness and experimental requirements.

2. Grinding bead specifications: Available in diameters ranging from 0.1 to 30 mm; small beads are ideal for fine grinding of soft samples, while large beads are suitable for breaking down tough tissues.

3. Final particle size: An optimized vertical oscillation mode, combined with appropriately sized grinding beads, achieves a final sample particle size of approximately 5 μm, enabling thorough release of cellular contents and meeting the requirements of downstream assays such as nucleic acid and protein extraction.

Multiple safety protection mechanisms and standardized maintenance can significantly extend the instrument’s service life.

1. Safety Design: A robust lid-lock mechanism ensures automatic shutdown upon opening, guaranteeing safe operation; equipped with multiple safeguards, including overload protection and abnormal‑stop alarms.

2. Routine Cleaning: After experiments, wipe the chamber and adapter surfaces with 75% ethanol to prevent sample residues from causing cross-contamination; do not rinse the interior directly with water.

3. Regular Maintenance: Periodically inspect the operating condition of linear bearings and keep the housing dry; if the unit is not used for an extended period, cover it with a dust‑proof cap and store it in a cool, dry place.

4. Warranty Information: The entire unit is covered by a one-year free warranty, with free repairs provided for non‑human‑caused damage. After the warranty period expires, lifetime technical support will be offered.
