Tissue Embedding Media
& Histology Reagents

ParaPro™ Blue

Tissue processing and embedding medium (paraffin) composed of light blue pellets. ParaPro™ Blue may be used with all tissues, but is ideal to use with small biopsy tissue specimens for better visualization of the tissue. Optimized for dermatology and urology specimens. A blend of highly refined paraffin with additives of synthetic polymers. Section down to 3µm thickness with excellent ribbon continuity; melting point 56°C. 

Sold in cases of 8 bags, 1kg/bag.

NEW Paraplast^®

Paraplast^® is recommended for general tissue processing and embedding. Paraplast^® is very compatible with tissue processor rotary valves. It is composed of a refined mixture of highly purified paraffin containing plastic polymers of regulated molecular weights. This supports improved tissue infiltration and quality sections with minimal compression. Paraplast^® gives brittle, difficult to section tissue an innate elasticity, promoting wrinkle-free sections. Melting point: 56°C (133°F) (ASTM).

Sold in cases of 8 bags, 1kg/bag.

Paraplast Plus^®

Tissue embedding medium for faster penetration. Paraplast Plus^® is recommended for large tissues and tissues which are difficult to process. Section down to 2µm thickness with excellent ribbon continuity; melts rapidly at 56-67°C. Double filtered paraffin containing plastic polymers of regulated molecular weights and a small percent (0.8%) of dimethyl sulphoxide (DMSO) for more efficient infiltration of dense and difficult to process tissues. No stainable residue. 

Sold in cases of 8 bags, 1kg/bag.

Paraplast X-TRA^® Tissue Embedding Medium

Optimum tissue embedding medium composed of clear pellets of low-molecular weight polymers and highly purified paraffin. A low viscosity paraffin. Low melting point of 52° to 54°C. Recommended for low temperature processing, small biopsy tissues and for general tissue embedding. Excellent sectioning qualities. Sections down to 2µm thickness with exceptional compression resistance and ribbon continuity. Cut sections are free of distortion; sample morphology is preserved. Low viscosity permits complete infiltration of dense tissue. Sections adhere perfectly to slides without leaving stainable residue. 

Sold in case of 8 bags, 1kg/bag.

NEW TissueGuard™ Gel

TissueGuard™ is an aqueous gel used to stabilize fragile histology and cytology specimens during processing. It encapsulates and retains specimens during histological processing while allow chemical reagents to penetrate the specimen. This is an alternate to other agarose stabilizers, appropriate for cytology and histology applications such as fine needle aspirates, urine specimens, needle biopsies, nerves, small arteries, aggregates, lymph nodes, small tissue fragments, or any other specimens utilizing cell block preparation. Product can be applied in either centrifuge tube, or in conjunction with BioMesh tissue cassettes, or using tissue paper. After application, specimen is ready for processing within minutes, or sooner if aided with a cooling block.  

This box contains 12 tubes, each with 10mL of Hydroxyethyl Agarose TissueGuard™ Gel. Cytology specimens must be ethanol preserved cell suspensions and histology specimens can be either formalin-fixed or unfixed tissue. Keep refrigerated when not in use and out of direct light. Once a tube of TissueGuard™ Gel has been opened, it is not recommended to use for longer than one week. For further technical information and protocols see the technical note below:

Polyshield^® Paraffin Repellent

PolyShield^® is a liquid paraffin repellent used as a protective coating on laboratory surfaces that are exposed to paraffin residue. PolyShield^® can also be used to clean paraffin that has adhered to lab countertops and equipment.
