A punch tool for the punching of a shape through a sheet of material. The punch tool includes a punch and a die portion disposed within a housing having a slot for receiving a sheet of material. A lower ramp is disposed within the housing and, when rotated, raises the punch to engage the die. The lower ramp may be rotated regardless of the orientation of the punch tool. Thus, the punch tool may be used even when in an inverted position.

Invertible punch tool

An automated liquid handler includes a probe assembly with a probe foot that can be moved down against the top of sample containers of a variety of sizes and shapes defined by racks, tubes or plates. A seal at the bottom of the foot provides a seal between the foot and the containers making it possible to prepare a SPE sample by using positive, probe introduced pressure within the containers to force liquid samples out through media at the bottom of the container. The foot seal is self sealing without the need for adhesives or other potential contaminates, and is removeably mounted to the probe foot.
