Abstract

Abstract A microscopic preparation marker includes a tape carrying a series of self-bonding marks which in use become preferentially bonded to the preparation. The device includes a spool with a supply of the marker-carrying substrate tape and another spool that drives the tape so that the tape leaves on the surface of the cover slide of the preparation, surrounding an area of interest that is to be later examined in more detail, a new mark each time the substrate tape is advanced and pressed against the cover glass. The device can be applied in scientific fields that use optical microscopes.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 132 words
A method for marking areas on surfaces of microscopic preparations to identify areas for further study, comprising: mounting a supply of circular marker-bearing tape to a slide revolver of a microscope, so as to extend along a path between a supply spool and a take-up spool; at a site intermediate the supply and take-up spools, successively pressing the tape against a surface of a microscopic preparation, and, in conjunction with each such pressing, advancing the tape in order to bring a next marker into position to be pressed onto the surface; the tape on the supply spool and to said site carrying a series of prefabricated circular markers each adapted to detach from the tape and preferentially attach to said surface when the tape at said site is pressed against said surface.
