Abstract
A selectively usable particle collector for recovering precious metals in clean condition during use of dental suction apparatus is shown. A reservoir where particles are deposited has a closure cap with ports to one of which can be removably attached a replaceable pick up tube to be inserted in the patient's mouth; the other is adapted to removably receive a flexible hose leading to a vacuum source both ports being in communication with the reservoir. In another embodiment a portion of the cap can be rotated to selectively effect either direct communication from the pick up tube to the flexible hose or through the reservoir. A metering vent is provided to regulate vacuum pressure.
