Knit-Trax Plain are 100% cotton cords that are knitted into interlocking chains to facilitate easy packing of cord into sulcus. This minimizes unraveling and fraying during packing. Also during crown preparation knitted cord will not entangle diamond burs. Knitted loops absorb and transport significantly greater quantities of hemostatic solution or gel providing more effective hemostasis. (100 inches [254 cm] per bottle). All Knit-Trax Cords can be soaked in hemostatic of choice with no contraindications for use with impression materials or epinephrine.
