Abstract
Disclosed is a ringing sealant defined by the addition of ethyl centralite to a solution of cellulose nitrate dissolved in acetone.

Claims10
A process of preparing a microscope slide ringing sealant comprising the steps of:
- dissolving ethyl centralite in a proportion equal to about 1% of the total weight of the resulting mixture in a solution of cellulose nitrate.
A ringing sealant for microscope slides, said sealant comprising:
- a cellulose nitrate lacquer made with an acetone solvent base plus an additive of ethyl centralite.
A method of preparing a microscope slide comprising the steps of:
- placing a specimen on a surface of the microscope slide;
- placing a cover glass on the specimen;
- and,
- applying a ringing sealant around the specimen and along a periphery of the cover glass so that a gap between the surface of the microscope slide and the cover glass is filled by the ringing sealant,
- allowing the ringing sealant to dry;
- and,
- wherein the ringing sealing comprises a cellulose nitrate lacquer made with an acetone solvent base plus an additive of ethyl centralite.
