1.3.4 Chemical Resistance of the Peristaltic Pump Tube (Isolera LS)
The Isolera LS system is delivered with two kinds of peristaltic pump tubes. Ensure that the used
pump tube is compatible with the solvents and sample to be used.
NOTE
The peristaltic pump tube has limited use. To avoid the risk of cross-
contamination and decreased pump performance, it is recommended that
the peristaltic pump tube is discarded after each run. If you still want to
reuse the peristaltic pump tube, clean the tube as soon as possible as
described in section 5.8.1 on page 5-5.
Limited: The peristaltic pump tube must be discarded after each run.
The chemical resistance was tested in room temperature as follows: The peristaltic tube was
1) weighed, 2) submerged in solvent for three hours, 3) dried and visually inspected, 4) submerged for
another three hours, 5) dried, visually inspected, and weighed, and 6) dried for 24 hours and weighed.
