Patch Removal
The Bresle Method DeFelsko Patch peels off the surface easier and
with less residue than conventional Bresle patches. Remove it
immediately after the test and dispose.
The Bresle Method PosiPatch lifts cleanly off the surface, with
absolutely no residue. The user may
choose to discard the PosiPatch and
begin the next test with a new one, or
simply rinse it with DI water and reuse
for several more tests until worn.
Rinsing the Test Cell
Rinse the test cell with unused DI
water several times after each
measurement, shaking the water out
after each rinse.
