1. A method for forming a peristaltic pump cassette, the method comprising:
- attaching at least one connector to a tubing segment;
applying a predetermined force to stretch the attached tubing segment;
cutting the attached tubing segment at a predetermined length; and
attaching the at least one connector with the tubing segment to the peristaltic pump cassette.

Abstract
A method for forming peristaltic pump cassettes includes cutting tubing segments to different lengths based on the physical properties of the individual tubing segments. The size variations compensate for the physical parameters of the tube and improve accuracy in a peristaltic pump using the cassettes.
