Krystalis microscope-slide ringing sealant is used to encase a mounted specimen between the coverslip and the slide. It has excellent adhesion to glass and dries clear, providing a solid, hard-wearing, waterproof barrier between a mounted specimen and the exterior environment. Krystalis is solvent (acetone) based. It was developed to complement Hoyer’s and Euparal mounting mediums but will aid in the creation of permanent mounts using Canada balsam and PVC mediums, providing a germ and fungus-free barrier that does not discolor over time. It is easy to apply and is sold in a range of sizes and in convenient brush-bottle and brush-pen containers. Use all appropriate safety measures when working with Krystalis sealant. Refer to the relevant safety data sheet(s).
