When cold mounting porous specimens it is purposeful to infiltrate them under vacuum, with a low viscosity mounting medium (epoxy resins). The QPREP infiltration device offers a solution for mounting under vacuum.
For transparent cold mounting using methyl methacrylate, these must be cured in a pressure device under positive pressure (2 - 2.5 bar). This increases the boiling point of the mounting material and suppresses the formation of gas bubbles during polymerization. The QPREP Pressure unit is best suited for this purpose.
Product Advantages
Recommended applications
Depending on the shape of the specimen to be mounted, the chosen hot mounting material, and the objectives of the materialographic preparation QPREP's wide range of accessories and tools ensures the best possible analysis results.
The specially designed collar of the new Qmould moulds, combined with the appropriate material selection, allows easy demoulding of the mounted specimens, ensures increased durability and stability of the moulds, and improves handling of the mould filled with mounting compound and the mounted specimen.
To help you choose, we have compiled a table of recommended mounting resin applications for the various mounting moulds.
Choosing a cold mounting mould of the correct size and suitable material the result of the mounting can be optimized. QPREP offers a variety of reusable and chemically resistant moulds of different sizes and materials for this purpose.
