When using this machine the operator, after inserting a full rack of filled tubes between the sealing jaws, manually closes and locks the sealing jaws starting the automatic heat sealing cycle. A light signals the end of the cycle when the jaws may be opened.
The hand operated machines are available in three jaw lenths: 4 inches, 8 inches, and 14 inches. To select the machine of correct length for your needs, allow approximately 1/4 inch between flattened tubes along the sealing jaws.
Production speeds are a function of the type of tube sealed and the skill of the operator. Two to four rack loads of tubes can usually be sealed per minute.
