Embodiments are directed to a removable cap with a top hole and a seal with a heat induction closure for sealing an opening of a container. Advantageously, the cap and the seal do not need to be removed for a probe to access contents of the container, when used in a diagnostic analyzer, thereby eliminating operator steps of cap removal and seal peeling/perforation. Automated opening of the cap and seal combination is provided by puncturing the seal. The seal retains its opened shape required for unobstructed, non-contact probe access to contents of the container. The seal is comprised of three layers: a first polymer sealing layer capable of being heat-sealed to a container; an aluminum foil layer on top of the first polymer sealing layer, configured to heat seal the first layer by inductive heating; and a second polymer layer on top of the aluminum foil layer for protection.
