Most mixing tips only cover a single cartridge range. This one is an exception: it works with both Flexitime Correct (reference 66002186) and Provil (reference 65209225), two Kulzer VPS silicones positioned as complementary ranges within the same mixing system. A practice using both materials can therefore keep just one tip reference in stock.
Flexitime is built around a flexible working-time concept: depending on the material chosen within the range, the practitioner adjusts the setting speed to their own clinical workflow, rather than being locked into a fixed time. Provil, an older line in the Kulzer catalogue, remains positioned for the same precision impression uses.
The 1:1 ratio matches the standard dosing of the two components. Manufacturer reference 66001988 corresponds to the 48-unit box.
