Abstract
We describe a fast method for firm attachment of large plastic sections to glass slides with EVA-copolymers, commonly known as hot melt sticks. Solid hot melt sticks dissolve slowly in xylene to form an adhesive gel within 6 hours. Small drops of hot melt gel are applied to the corners of the sections and surrounding slide surface at ambient or elevated temperatures. The gel sticks to both the plastic and the glass slides. The hot melt “corner point method” prevented detachment of sections in staining procedures. As an additional technique, we suggest the use of hot melt adhesive for attaching plastic specimen blocks to wooden blocks or metallic specimen holders.
