Abstract

The invention relates to a lab-top work station which is designed for use in the manual application of liquid to a slide or microwell plate and consists of a slide holder, a bridge for support of manual liquid dispensers at a predetermined location with respect to the slide holder, and a manual incremental advance mechanism for manually moving the slide holder a predetermined distance.

Claims

1. A manual lab-top work station comprised of a fat base means, a slide or plate holding means supported on said flat base means between guide means, a bridge means adapted to support a manual liquid dispensing pipette means having a plurality of manual liquid dispensing pipette tip means at a predetermined location with respect to said slide or plate holding means and to guide the pipette means to a precise plate or slide location, bridge support means horizontally fixed to said flat base means for supporting the bridge means above said flat base means for incrementally manually moving said slide or plate holding means a predetermined distance on said flat base means and wherein said guide means guides the slide or plate means in a fixed orientation past said horizontally fixed bridge support means.

2. The work station of claim 1 wherein said slide or plate holding means has a plurality of recesses for manual removal of a slide or plate from said slide or plate holding means.

4. The work station of claim 1 wherein said bridge support means have a plurality of slots adapted to support bridges at different heights above the slide or plate holding means.

5. The work station of claim 1 wherein said bridge means has a plurality of notches adapted to hold pipette dispensers in place with respect to said slide or plate holding means.

6. The work station of claim 1 wherein said bridge means has a pair of slots counterbored at an end adapted to fit in said bridge support means.

7. The work station of claim 1 wherein said bridge support means have snap lock pins adapted to hold said bridge means in horizontally fixed position.

8. The work station of claim 1 wherein said means for manually moving said slide or plate holding means include a notched incremental control rod with both a notched and flat surface adapted to engage a ratchet clip to move said slide or plate holding means.

3. The work station of claim wherein said slide or plate holding means is square in shape with a rectangular recess adapted to receive and hold a slide or plate in a desired orientation with respect to the pipette means.
