Cargille Mounting Media

Cargille Meltmount^TM for Microscopy and Optical Coupling

The Cargille Meltmount^TM series of mounting media are specially formulated optical-quality thermoplastics for use in microscope slide mounting and in other optical coupling applications

Cargille Meltmounts^TM Are:

• Instant - they are thermal mountants and require "no oven time"
• 100% useable - contain no solvents
  
• Less Expensive per slide
  
• Reversible - thermally, for particle retrieval or re-orientation
  
• Soluble - in toluene if needed for special techniques or clean-up
  
• Fluid - at 65°C - a temperature chosen because it makes a permanent mount and protects the majority of specimens from thermal changes.
• PCB-FREE
  
• Direct replacements for "older style" media

Notes on use:

• Meltmount is a Thermal Plastic Material. This means its viscosity is dependent on temperature (inversely dependent). As the temperature increases the viscosity decreases. There is no sharp melting point. Being thermal plastic, it is capable of "cold flow". This means the Meltmount, the specimen, the slide, and the cover slip can all move independently of each other given a mix of time, temperature, and lateral pressure or gravity.
  
  
• Storage of prepared slide: treat them as the valuable items they are. Store:
  • Flat, cover slip on top
  • In the dark
  • Away from dust and fumes
  • At 60° to 85°F. Meltmount is meant to be thermally reversible, don't allow this to happen inadvertently by storing or transporting prepared slide above 85°F.

Meltmount^TM Price List and Description

MELTMOUNT* 1.539       Code 53      Cat.#24140       Patent Pending       51.00/fl.oz.

Meltmount* 1.539 has a refractive index (nD @ 25°C) of 1.539 and an Abbe V dispersion of 45 making it optically similar to Canada Balsam and, therefore, ideal for mounting many biological specimens but without the long drying time of Canada Balsam.

MELTMOUNT* FOR CHRYSOTILE ASBESTOS      Code 25761       Cat.#24145       Patent Pending       101.00/fl.oz.

Meltmount* Code 25761 has dispersion characteristics making it appropriate for mounting chrysotile asbestos.

MELTMOUNT* 1.582       Code 5870      Cat.#24150       Patented        51.00/fl.oz.

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       Code 5870      Cat.#24152       Patented       51.00/fl.oz.

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       Code 5870      Cat.#24160       Patented       51.00/fl.oz.

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       Code 5870      Cat.#24165       Patented       51.00/fl.oz.

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       Code 5870      Cat.#24170       Patented       51.00/fl.oz.

Meltmount* 1.704 has a refractive index (ND @ 25°C) of 1.704, similar to naphrax, and an Abbe V dispersion of 24.

QUICK-STICK^TM

Cargille Meltmount* is now available in a convenient stick form called Quick-Stick*. It can be used to make permanent microscope slide mounts quickly.

Quick-Stick* 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.

R&D Laboratory
