The Osseous Coagulum Trap (OCT) offers an improved method of collecting osseous material. Osseous material is collected directly from the aspirator tip into a sterile filter. It is also excellent for retrieving root tips and precious metals. The OCT can be chemiclaved, autoclaved or dry heat sterilized. It comes with three filters. Additional filters are available in packages of three. The OCT connects into a high volume cut-off valve or 1/4" surgical tubing. Any surgical aspirator that fits a high volume cut-off valve will fit into the OCT cap.
