Technovit® 9100

Newly introduced! Technovit® 9100 is an embedding medium system based on methyl methacrylate (MMA), which hardens at low temperature. It is designed for the embedding of mineralized tissues with extensive possibilities of staining for light microscopy.

Applications:

• Heavy duty microtome technique for preparing thin sections – such as pelvic biopsy, small low and high density bone samples.
• Cutting grinding and micro-grinding system (contact point technique) - such as jaw and teeth segments with and without implant.
• Combined contact point and heavy duty microtome technique (target preparation) - such as interface regions and examination of tissues surrounding metal implants and cement-free endoprothesis (target tissue preparation).

Properties:

Technovit® 9100 Polymerization takes place under the exclusion of oxygen with the help of a peroxide/amine catalyst. Additional components such as PMMA-powder and a regulator allows for a controlled polymerization at temperatures between –8 and –20°C, which guarantees for the dispersion of the heat generated during polymerization. The polymerization time is between 18 and 24 hours using a volume between 3 and 15 ml in the above temperature range. All the routine techniques such as preparation tissues, staining, immuno- and enzyme-histochemistry, in-situ hybridization techniques can be performed.

• Basic Solution – is composed of organic monomers, with at least one carbon-carbon double bond (C=C). The stabilizer added to this solution is for storage-stability. Hydrophilic properties are improved by the addition of a special hydrophilic generating agent.
• PMMA-Powder – is an internal filler and it is made up of PMMAmicro pellets. It is used to:
  - Reduce the polymerization shrinking effect.
  - Reduce the heat generated during the polymerization process.
  - Improve the quality of the polymerization block.

• Hardener 1 – is one of the components of the polymerization initiation system. It is a derivative of dibenzoyl peroxide, which in combination with Hardener 2, makes the polymerization take place.
• Hardener 2 – it works catalytically upon hardener 1 to allows for a controlled polymerization, even at temperatures below 0°C.
• Regulator – is composed of a reactive organic compound, which allows a controlled polymerization, even with large volumes of polymer, without increases in the temperature during the polymerization reaction.
• PMMA-Granulate, EXART® - this granulate acts as an additional internal filler when larger amounts (500-1000 ml) of polymer are to be used, for example, in the case of femur shaft with noncemented endoprosthses. The amount of monomer (basic solution) is thereby reduced, at the same time making the polymerization easier to control.
