What is typically contained within a peristaltic pump's flexible tube?

A peristaltic pump is designed to move fluids through a flexible tube by means of rollers or shoes that compress the tube in a rhythmic manner. This mechanism creates a vacuum that draws the fluid into the section of the tube that is being compressed, allowing it to be pushed forward without contact between the fluid and the pump's mechanisms.

The primary function of a peristaltic pump is to transport liquids, making fluids the correct and most relevant choice. The design allows for the handling of various types of fluids, including viscous or sensitive ones, without risk of contamination, as the liquid does not touch the pump's internal components. Consequently, options such as air, solid particles, or gases are not typically suitable for transportation through this type of pump, as they do not align with its intended purpose of conveying liquid substances safely and effectively.
