For repairing valve leaks in a used AKTA protein purifier, you can take the following steps: 1. Locate the leaking valve: Inspect all valves and their connections for visible signs of leakage, such as dripping liquid or loose fittings. 2. Basic troubleshooting: Tighten any loose connections appropriately (avoid over-tightening to prevent component damage), and clean the valve seals and surrounding areas to remove debris that may affect sealing performance. 3. Replace worn components: If the leak is caused by damaged seals, gaskets, or O-rings, replace them with compatible genuine spare parts to restore proper sealing. 4. Professional repair support: If the above measures do not resolve the issue, or if the valve body itself is damaged, it is recommended to seek help from a professional instrument maintenance service provider.
