1. A take-up reel in an apparatus for removal of a film seal covering substantially a full width of a plate containing a plurality of liquid samples in discrete wells, wherein the apparatus comprises a source roll of adhesive tape having a tape width substantially the same as a width of the film seal, a first tape path portion, a translation means for moving the plate relative to the first tape path, a collection rod within the first tape path for pressing the adhesive tape against the film seal as the plate is moved past the collection rod, a take-up spindle disposed within a second tape path portion substantially perpendicular to the first tape path portion for supporting a take-up reel and a driver to rotate the take-up spindle, the take-up reel comprising:

  • a cylinder releasably supported on the take-up spindle for receiving a leading end of the adhesive tape and rotating to collect used adhesive tape and removed film seal that is adhered to the adhesive tape, the cylinder having a length substantially the same as the tape width;

    a first side flange and a second side flange disposed on opposite ends of the cylinder the first and second side flanges adapted center the used adhesive tape and removed film seal on the cylinder and to at least partially contain residual liquid on the used adhesive tape and removed film seal; and

    means for preventing slippage of the take-up reel relative to the take-up spindle and maintaining a uniform pulling force on the adhesive tape to pull the adhesive tape along the tape path during rotation of the take-up reel, wherein the pulling force produces a lifting motion at the collection rod to peel the film seal away from the plate.
