Sigmacote® is a solution of a chlorinated organopolysiloxane in heptane that readily forms a covalent, microscopically thin film on glass. The film repels water, retards the clotting of blood or plasma, and prevents surface adsorption of many basic proteins. Ready to use without dilution; reusable if kept free of moisture.
Sigmacote® has been used to prevent adhesion of the growth factors to plasticware. It has also been used to coat coverslip in order to prevent the adhesion of larval brain during squashing.
Sigmacote® is ideal for glass, ceramics and fiber optics. It is used to treat GC injection glass inserts.
