Capilary PTFE
Capillary PTFE refers to a type of tubing or capillary made from polytetrafluoroethylene (PTFE), a synthetic fluoropolymer known for its exceptional chemical resistance, heat resistance, and non-stick properties.
PTFE is a high-performance polymer composed of carbon and fluorine atoms. It is known for its unique molecular structure, which imparts excellent properties such as chemical inertness, low friction, and high temperature resistance.
Capillary PTFE tubing is characterized by its small diameter, typically ranging from fractions of a millimeter to a few millimeters in size. This fine diameter allows for precise fluid handling and sample delivery in analytical instrumentation, chromatography, medical devices, and other applications where precise fluid control is essential.
Despite its small diameter, Capillary PTFE tubing remains flexible and pliable, allowing for easy handling and routing in complex systems or tight spaces. It is also highly durable and resistant to mechanical abrasion, ensuring long-term reliability and performance in demanding environments.
Maintenance and replacement:
- Visual Check: Inspect the PTFE capillary tube for any signs of physical damage, such as cuts, abrasions, or discoloration.
- Handle capillary tubes with care to avoid bending, kinking, or excessive pressure that could cause damage or affect the flow characteristics.
- Physical Damage: Visible cuts, scratches, or wear that compromise the integrity of the capillary tube may indicate that they need to be changed
- Performance Issues: Reduced flow rate, inconsistent results in applications (e.g., chromatography), or leaks due to tube damage is a sign that they need to be replaced.
-
Chemical Compatibility: If the tube has been exposed to incompatible chemicals that may have caused degradation, you may need to replace capilary.
- Storage: Store spare capillary PTFE tubes in a clean, dry environment away from direct sunlight and extreme temperatures to prevent degradation.
