When selecting PTFE capillary tubes, several key points need to be considered. First, pay attention to the tube diameter, as this directly affects its performance in practical applications. Second, corrosion resistance is an important consideration, as PTFE material has excellent corrosion resistance and can withstand various harsh environments. Furthermore, the accuracy and stability of the capillary tube must be considered, both of which are crucial for high-precision measurement and control applications. Finally, price and delivery time are also factors that cannot be ignored, as they directly affect project costs and schedules.
Here are some practical suggestions for selecting PTFE capillary tubes:
First, prioritize high-quality PTFE material, as this directly determines the tube's chemical stability and high-temperature resistance.
Second, avoid selecting excessively thin capillary tubes, as slow flow rates will affect separation efficiency.
Furthermore, during use, be sure to avoid bending or flattening the tube to ensure its performance and lifespan are not affected.
