JB-4 Embedding Kit

Polysciences' JB-4 is a water-soluble, GMA based, plastic resin kit intended for use in the preparation of embedded samples for high resolution light microscopy. It is a technique now widely used for research and clinical diagnosis. JB-4 yields semi-thin sections (0.5μ-2.0μ) with excellent morphological preservation. Clear casts are obtained in 90 minutes or less at room temperature. JB-4 is the leading water-soluble plastic embedding kit for light microscopy. It has been successfully used in enzyme histochemistry, immunohistochemistry, immunofluorescence, and auto-radiography.

Poly-Mount

PolyBed 812/DMP-30 Kit

PolyBed 812 is an exact chemical match for Epon 812. Can be substituted in previously developed formulations based on Epon 812. Useful as an embedding medium with acetone or ethanol dehydration. Loss of phospholipids can be kept below 10%.

Osmium Tetroxide, Crystalline, 99.95%

For use in electron microscopy.
Post fix and stain for E.M. Supplied in pre-scored ampoules sealed in plastic bags. The ampoules are label free to avoid cleaning prior to preparation of solutions. Each ampoule is equipped with an ampoule cracker. *Poison pack charge required 

Glutaraldehyde, EM Grade, 70%

Spurr Low-Viscosity Embedding Kit

Exceptional penetration for tissue, mineral, and dense structures. A low viscosity of 60cps allows easy penetration into a variety of difficult materials. May be used to prepare mineral specimens for polishing. The low viscosity of the Spurr formulation allows rapid infiltration into tissues, minerals, and other dense structures. Facilitates embedments with high lipid contents or hard membranes, or highly vacuolated parenchymous tissues.
