Operation Manual

SECULIFE IF+
20 GMC-I Messtechnik GmbH
To optimize the performance of the SECULIFE IF+, it is recommended that a wetting agent be used to
minimize the surface tension of the test solution. The test solution should be Distilled water mixed with
“MICRO-90.” “MICRO-90” can be purchased from Cole- Parmer in a 1% solution (Part Number A-
18100-01, www.coleparmer.com, 1-800-323-4340). Further dilute the “MICRO –90” by using one part
of “MICRO-90” to 10 parts of Distilled water. If foaming becomes a problem, dilute the “MICRO-90” to a
20:1 solution.
The sheeting action of the test solution has a minor effect on test results. It is recommended to discard
the first reading of a device under test. Run the test and then repeat the test. Only record data from the
second test.
Any droplets remaining in the chamber after a test run will affect the accuracy of the test results.
Adjust the drain rate to minimize the droplets.
OPTIMIZING MEASUREMENTS
CAUTION - FLUID
Only distilled water should be used in the
chambers with the SECULIFE IF+. Do not use tap
water, glucose or any other fluid; this will cause
the tubing to become contaminated.
