Paramat is the original British blend of paraffin wax and plastic polymers and it has been used in histology labs throughout the world for over 20 years. It has been found that when plastic polymers are added to the paraffin the elasticity of the final block is greater as compared with paraffin alone. As well the mixture offers improved tissue penetration, easier ribboning of sections, reduced tendency to crumble, and improved overall results with fibrous tissue.
A recent development to Paramat is the addition of a very small amount of dimethyl sulfoxide (DMSO) which produces PARAMAT EXTRA. This formulation offers additional advantages, such as faster penetration of the tissue with a more homogeneous matrix to support the specimen.

Asynthetic polyester wax with a verylow melting point (37°C). Invented by Dr. H.F. Steedman, as a ribboning embedding medium. Its main advantage over paraffin and ester waxes is its low melting point, which reduces tissue hardening, shrinkage, and eliminates the need for infiltration ovens.
The wax is soluble in most organic solvents, including alcohol, ethers, esters, ketones and hydrocarbons. The wax is water tolerant, almost opaque, and sections easily. No electrification of ribbons occurs during sectioning. Sections of 2 microns and more may be cut at room temperatures between 10 and 22°C. It is advantageous to keep the wax in its solid state prior to use.

Polyfin is a mixture of highly refined paraffins and co-polymer alloys in a convenient wax pellet. This unique formulation provides optimal tissue support while maintaining exceptional clarity. Our Polyfin™ has been institutionally tested and found to function flawlessly in pressure/vacuum fluid flow processors. Its low melting point (55°C) eliminates any tissue distortion caused by excessive heat during processing. In a recent study conducted by a Medical Center Histologist, monitored by a CPA firm using standard blind protocols, POLYFIN™ clearly demonstrated the least compression of seven popular paraffins.

This gel is highly viscous, water-soluble embedding medium for frozen sections that "stays put". The gel is packaged in a pump-dispenser bottle that instantly dispenses the gel in any desired position. The dispenser has a built-in "guillotine" that cleanly severs the gel from the pump spout and prevents any "stringy" medium from pulling away when the bottle is removed. Simply dispense gel on a room temperature block-holder. Use cold heat extractor to form a base layer. Dispense additional gel. Place the tissue on top of gel. Use cold heat extractor to freeze tissue and form block.

A water soluble embedding media which is based on Glycol Methacrylate (GMA) plastic embedding. It is intended for use in preparing samples for high resolution microscopes (HRLM). The catalyzed monomer acts as a dehydration and infiltration agent; therefore, complete dehydration through 100% ethanol is not necessary (although recommended for large or dense tissues). Conventional paraffin sections have a greater degree of shrinkage and produce inadequate morphology when compared to JB-4.
- Thin sections (.5-2.0 micron) with excellent morphological structure preservation
- Water-clear blocks; casts in 90 minutes max. at room temp
- Good lipid and enzyme retention when processing at low temperatures (4°C)
- Removal of JB-4 resin prior to staining is not necessary
- Clearing agents such as xylene and chloroform are not needed
- Higher clarity and contrast than with paraffin sections
- Easy processing of difficult specimens such as calcified bone and delicate embryonic tissue
- It produces harder blocks which is ideal for dense samples, such as bone
