Abstract
A reciprocable vertical shafts 21 has a pyramid shaped lower tip for piercing a sealing foil 8d secured across the top of an analyzer test cup containing an active substance. The edges of the pyramid divide the foil into triangular segments which are pressed against the inner wall of the cup by the cylindrical root portion of the shaft such that they do not engage any of the active substance or interfere with subsequent injections into or withdrawals from the cup.
