ABSTRACT:
A pusher blade and its housing are described, in which the blade has a stiff front end for engaging slide-type test elements, and a flexible body portion and back end. The housing forces the blade to curve through an angle, preferably about 90.degree. C., to minimize the extension in one direction the blade would have if it were entirely rigid.
The housing can provide for separate stacks of elements in separate environments to be engaged by the blade, since sealing means are provided for preventing substantial intermixing of the environments when the blade is activated.
