Automatic system for washing sample vessels - includes lever system connected to belt drive which operates diaphragm pump and simultaneously moves spray jet to wash out sample vessel

摘要

Automatic system for washing sample vessels on a conveyor belt is claimed. A diaphragm pump is connected to the belt drive mechanism. This feeds wash liquid to a nozzle for spraying into the sample vessel at the appropriate point. The nozzle is connected to a lever arm which is also synchronised with the pump drive. Thus, the whole action is synchronised with that of the belt and has a common drive. For use on automatic analysis equipment. By having a common drive mechanism, it avoids the need for separate pneumatic or hydraulic drive mechanisms to operate the wash system.
