Key Considerations for High Purity Tubing

When selecting or buying high purity tubing, several key considerations should be taken into account:

  1. Material: High purity tubing is typically made from materials such as fluoropolymers (e.g., PTFE, FEP, PFA), polyethylene, polypropylene, or other specialty polymers. The material chosen should be compatible with the intended application and the substances it will come into contact with.

  2. Purity Level: High purity tubing is designed to minimize leaching of contaminants into the fluid being transported. Ensure that the tubing meets the required purity standards for your specific application.

  3. Size and Dimensions: Consider the inner and outer diameters, wall thickness, and length of the tubing to ensure it can accommodate the necessary flow rates and pressures in your system.

  4. Temperature and Chemical Compatibility: High purity tubing should be compatible with the temperature range and chemicals used in your application to prevent degradation or contamination.

  5. Flexibility and Bend Radius: Evaluate the flexibility and bend radius of the tubing to ensure it can be easily installed and routed without kinking or collapsing.

  6. Sterilization and Cleanability: In applications requiring frequent sterilization or cleaning, choose tubing that can withstand the required sterilization methods (e.g., autoclaving, gamma irradiation) without compromising performance.

  7. Regulatory Compliance: Ensure that the high purity tubing complies with relevant industry standards and regulations, such as FDA, USP Class VI, or ISO standards, depending on the intended use.

  8. Manufacturer and Quality Assurance: Consider sourcing high purity tubing from reputable manufacturers known for product quality, consistency, and reliability. Look for certifications or quality control measures implemented by the manufacturer.

By considering these factors, you can select high purity tubing that meets the specific requirements of your application while ensuring optimal performance and product integrity.
