Using magnetic beads as the carrier, using the principle that magnetic beads adsorb nucleic acid under high salt and low pH value, and separate from nucleic acid under low salt and high pH value, and then move the magnetic beads or transfer the liquid to realize the entire extraction and purification process of nucleic acid. Due to the uniqueness of its principle, it can be designed into a variety of throughputs, which can be extracted from a single tube or 8-96 samples, and its operation is simple and fast. It only takes 30-45 minutes to extract 96 samples, which greatly improves the The experimental efficiency is low and the cost is low, so it can be used in different laboratories, and it is the mainstream instrument on the market.

Lithium battery evaluation test project
**Lithium Battery Evaluation Test Projects**
**Definition**
- **Fully Charged**: The battery must meet the manufacturer's specified capacity and be charged under recommended conditions (current, voltage, temperature, time, etc.). The battery should be used within one week after charging.
- **Fully Discharged**: The battery is discharged according to the manufacturer’s recommended discharge conditions (current, temperature, etc.) until the specified discharge voltage is reached. The battery should be used within one week after discharging.
- **Newly Produced Battery**: The battery should be less than one month old and have undergone fewer than XX charge-discharge cycles.
- **Battery Cycle**: A cycle refers to a continuous charge and discharge process following the manufacturer’s recommended conditions, where the battery’s calculated capacity has dropped by 40% to 60%.
- **Room Temperature**: In testing, room temperature refers to 20±5°C. This is the standard temperature for most tests.
- **Explosion**: An internal explosion or damage caused by cracking of the battery casing.
- **Fire**: A fire caused by spontaneous combustion or burning inside the battery.
- **Safety Valve Operation**: The safety valve opens during normal use to release internal pressure.
- **Deformation**: Obvious visible deformation due to external or internal pressure.
**Evaluation Test Projects**
**(1) Electrical Tests**
- **External Short Circuit**: Fully charged, newly produced battery at 60°C. Use a resistance of less than 50mΩ to short the two poles. No explosion or fire for more than 6 hours.
- **Forced Discharge**: Fully charged, newly produced battery at room temperature. Discharge to 250% of the rated capacity. If safety mechanisms activate, the test can be stopped without explosion or fire.
- **Continuous Charge and Discharge**: Newly produced battery at room temperature. Charge and discharge continuously for 28 days without explosion, fire, or cracking.
- **Overcharge**: Fully charged, newly produced battery at room temperature. Charge to 250% of the rated capacity. If safety mechanisms are triggered, the test can be stopped without explosion or fire.
- **High-Current Charging**: Newly produced battery at room temperature. Charge with three times the recommended current until over 100% of the rated capacity. No explosion or fire.
**(2) Mechanical Performance Tests**
- **Vibration**: Fully charged or fully discharged, newly produced battery at room temperature. Vibrate in three directions (XYZ) for 100 minutes, amplitude 0.8mm, frequency from 10Hz to 100Hz. After the test, recharge the battery. No explosion, fire, or deformation.
- **Acceleration**: Fully charged or fully discharged, newly produced battery at room temperature. Apply acceleration of 75g, reaching up to -175g in XYZ directions. After testing, recharge the battery. No explosion, fire, or deformation.
- **Drop Test**: Fully charged or fully discharged, newly produced battery at room temperature. Drop from 1.9m height 10 times onto concrete. No explosion or fire.
- **Nail Penetration**: Fully charged, newly produced battery at room temperature. Insert a nail (diameter 2.5–5mm) through the center axis for 6 hours. No explosion or fire.
- **Squeeze Test**: Fully charged, newly produced battery at room temperature. Squeeze between two flat plates with 13kN pressure. No explosion or fire.
- **Impact Test**: Fully charged, newly produced battery at room temperature. Drop a 9.1kg weight from 61cm height onto the top of the battery. No explosion or fire.
- **Water Drop Test**: Fully charged, newly produced battery at room temperature. Drop from 10m height into water. No explosion or fire.
**(3) Environmental Performance Tests**
- **High-Temperature Storage**: Fully charged, newly produced battery. Store at 100°C for 5 hours, then cool down to 20°C for 24 hours. No explosion or fire after 24 hours.
