The CoMax has a special patented ergonomic mechanism for comfortable handling. The handle minimizes the dispensing force needed to express heavily filled composites. The top flange is pulled back to insert a compule, and easily pulled back again to release it. The CoMax accepts most mfg.’s composite compules. The unit is autoclaveable, and carries a 2 year warranty. The CoMax Composite Dispenser received a 5 Star Award from Reality Publishing.
