Ameda's exclusive milk collection system has a unique silicone diaphragm that prevents moisture and milk from entering the tubing. Therefore, under normal use there's no need to clean the pump tubing. This Eco kit can only be used with the Ameda electric breast pump. The bottle has a locking ring cap only, this means it can not be used as a feeding bottle. The milk collection system can only be use to pump into the supplied bottle (will not fit a standard thread baby bottle or milk collection bag). Can not be used to convert between electric and manual pump.
