ABSTRACT:
Unitary biological processing apparatus for processing specimens therein is described wherein a perforated receptacle member with two arc shaped abutment means and a third hook shaped abutment means is attached through a frangible hinge portion to a perforated lid member with two arc shaped detent means at the two edges of the lid member which are perpendicular to the lid member edge extending along the hinge portion, and a third detent means engageable with the hook shaped abutment means. When the lid member is swung about the hinge the arc shaped engagement means become engaged even before the lid member mates against the receptacle member and the two arc shaped engagement means provide with the third engagement means a three-point lock of the lid member onto the receptacle member.
