Equipping a dental laboratory: making a plaster trap.
A plaster trap is a necessity for any dental laboratory. This article describes a technique for making an inexpensive plaster trap from a 3 1/2 gallon bucket and two trap adaptors. The materials are readily available and the armamentarium necessary to assemble the plaster trap is minimal. Making a plaster trap has two advantages. First, it can be made for a fraction of the cost of those purchased commercially and second, the plaster trap is easily cleaned by replacing the bucket without remaking the lid portion.
