Abstract
A wafer for use in selectively connecting and disconnecting plastic tubes is in the form of a heatable plate having side walls and having a leading end and a trailing end. An outwardly extending scoop is formed on each of the side walls between and spaced from the leading end and the trailing end. A pair of slits is formed in the trailing end in line with the scoops for reducing the amount of plastic material remaining on the wafer.
