Description

Duotest Papers are indicator papers having two complementary indicator zones, separated by a white centre band.

These papers have the following advantages:

Greater accuracy - two different indicator zones on one strip.
Better readability - white centre strip is hydrophobic, does not absorb liquids and hence acts as a contrast medium.
Higher mechanical strength - white centre retains same physical strength as in its dry state.
Dispenser is designed so that end of paper strip is always within reach. No need to open dispenser to retrieve end.
Dispenser design permits fast and easy insertion of readily available, economically priced replacement reels.
