PTFE Tubing vs Rubber Tubing: Understanding the Differences

PTFE (Polytetrafluoroethylene) and rubber tubing are two different materials used for laboratory applications.

PTFE tubing has several advantages over rubber tubing. PTFE is highly resistant to chemicals, including strong acids, bases, and organic solvents, and is capable of withstanding high temperatures. It is also highly resistant to water absorption and has a low coefficient of friction, making it easy to clean and sterilize. PTFE is also biocompatible, making it suitable for use in biological applications.

On the other hand, rubber tubing is a more flexible material that is easier to stretch and bend. It is also less expensive than PTFE tubing. However, rubber tubing is less resistant to chemicals and may not be suitable for use with strong acids or organic solvents. Rubber tubing can also be prone to degradation over time, especially when exposed to heat, light, or other environmental factors.

In summary, PTFE tubing is a more durable and chemical-resistant option for laboratory applications, while rubber tubing is a more flexible and cost-effective option that may be suitable for less demanding applications.
