Endless potential for efficiency and productivity

The Tissue-Tek® Paraform® Sectionable Cassette System is a novel, innovative, two-part system that helps provide your lab with ultimate productivity.

The Tissue-Tek® Paraform® Sectionable Cassette System is a true innovation in cassette design. The two-part system is composed of a rugged frame and a cassette insert made of an inert proprietary material.

Its unique sectionability makes Tissue-Tek® Paraform® a significant improvement over standard cassettes. Specimen orientation can now be preserved from grossing through to microtomy by simply orienting the grossed specimen in 1 of 6 available Tissue-Tek® Paraform® cassette types: Standard, Biopsy, Orientation, Shaved Biopsy, Core Biopsy, or the 13 x 13 insert, eliminating repeats caused by improper orientation.

After grossing, the tissue section is placed into the Tissue-Tek® Paraform® cassette, positioned as it should be cut, and processed in any tissue processor. The proprietary material is able to withstand exposure to all the volatile reagents and fixatives typically used in histology. Once the Tissue-Tek® Paraform® cassettes are removed from the processor, they are ready for embedding. The Tissue-Tek® Paraform® cassette eliminates the need to open the cassette and reorient tissue during embedding, thus simplifying embedding, increasing productivity, and streamlining tissue preparation.

The Tissue-Tek® Paraform® material used for the cassette has sectioning characteristics similar to paraffin. It lets you cut right through the cassette bottom without artifacts and without damage to the blade. The inert Tissue-Tek® Paraform® material does not pick up stain and does not interfere with microscopic examination.

Although the Tissue-Tek® Paraform® cassette is designed for use with the Tissue-Tek AutoTEC®, Tissue-Tek® Paraform® is compatible with all existing laboratory methods and manual embedding processes. In addition, the 6 unique cassette types accommodate a variety of specimens, even those requiring special orientation such as skin or arterial specimens.

Tissue-Tek® Paraform® provides total automation of the embedding process when used with the Tissue-Tek AutoTEC® Automated Embedding System.



The six innovative cassettes (Biopsy 13mm x 13mm, Standard, Biopsy, Shaved Biopsy, Orientation, Core Biopsy) secure the tissue through processing and  embedding
  • Prevents loss of tissue and misorientation during processing and embedding
The cassettes can be printed and barcoded at grossing, providing accurate tracking of specimens
  • Reduces risk of lost or mislabeled specimens through the processing and embedding 
The Paraform Cassettes can be easily faced by Sakura or other manufacturers' microtome blades
  • Eliminates the need to change the current implemented sectioning process
The Paraform Cassettes can be utilized on most conventional processors, rapid processors, manual, and automated embedding systems
  • Minimizes changes in present implemented processing or embedding systems
