Meltmounts™, Electron Microscopy Sciences
Supplier: Electron Microscopy Sciences
Cargille Meltmount™ (optical quality) is a series of mounting media which are specifically formulated for use in microscope slide mounting and in other optical coupling applications.
- Instant thermal mountants that require no-oven-time
- 100% Usable; contains no solvents
- Reversible, thermally, for particle retrieval or re-orientation
- Soluble in toluene for special techniques or clean-up
- Fluid at 65 °C, a temperature chosen because it makes permanent mount and protects the majority of specimens from thermal changes
- PCB-Free
- It is a direct replacement for old mountant mediums (Canada Balsam, Aroclor 5442, Naphrax...)
Melt Mount is also available in a Quick-Stick™ form which can be used to make permanent microscope slide mounts quickly. These Melt Mount sticks can be applied to a slide on a hotplate. As soon as the specimen and cover glass are positioned, and the slide is cooled you have a permanent prepared slide that can be reversed by reheating if you should wish to retrieve a particular particle. Each Quick-Stick™ weighs approximately 2/3 oz. (18 g).
Meltmount™ 1.539 has a refractive index (nD @25 °C) of 1.539 and an Abbe V dispersion of 45. Its optically like Canada Balsam and therefore ideal for mounting many biological specimens but without the long drying time of Canada Balsam. Meltmount™ for Chrysotile Asbestos has dispersion characteristics making it appropriate for mounting chrysotile asbestos.
Meltmount™ 1.582 has a refractive index (nD @25 °C) of 1.582 and an Abbe V dispersion of 33. Its optical clarity makes it the preferred choice for minimum visible absorption. Meltmount™ 1.605 has a refractive index (nD @25 °C) of 1.605 and an Abbe V dispersion of 30, making it appropriate for mounting Asbestiform Tremolite, Anthophyllite, and Actinolite.
Meltmount™ 1.662 has a refractive index (nD @25 °C) of 1.662 and an Abbe V dispersion of 26, optically similar to Aroclor 5442 but is PCB-free.
Meltmount™ 1.680 has a refractive index (nD @25 °C) of 1.680 and an Abbe V dispersion of 25, making it appropriate for mounting Amosite and Crocidolite asbestos. Meltmount™ 1.704 has a refractive index (nD @25 °C) of 1.704 and an Abbe V dispersion of 24, similar to Naphrax.
