Protein purification injection valveFunction of:

1. Sample introduction: Select the injection port by rotating the valve body, and introduce the pre treated sample (such as centrifuged or filtered protein solution) into the system.

2. Flow path switching: After the sample fills the valve body, switch to the flow state and push the sample to the chromatographic column.

3. Multi channel support: supports multiple injection methods, can be switched without changing the pipeline, and adapts to samples of different volumes.

Key selection points:

1. Number of channels: Select according to the scale of the experiment (such as using 2 bits and 4 channels for small-scale experiments, and 6 bits and 14 channels for large-scale experiments).

2. Pressure resistance and flow rate: Models with a pressure resistance of over 10MPa are required for high-pressure experiments, and the flow rate range should cover the experimental requirements (such as 0-200mL/min).

3. Material: Components in contact with the sample must be resistant to chemical corrosion.

Maintenance points:

1. Regular cleaning: Avoid residual contamination of the sample.

2. Sealing inspection: prevent leakage from causing experimental failure.

3. Follow the operating procedures: ensure safety and experimental reproducibility.

　　Protein purification injection valveThrough its precise structural design and operational procedures, it provides an efficient and reliable sample introduction solution for protein purification. Strictly following the operating procedures and regular maintenance during use can maximize its performance advantages.
