L.R. White Embedding Media

L.R. White is the first low viscosity acrylic embedding medium product made by London Resin Company. Used for routine light and electron microscopy, histochemisty and immunohistochemistry, L.R. White can be cold or thermally cured. Accelerator for room temperature curing of the resin is available for those applications where simple heat catalysis is inappropriate.

L.R. White and L.R. Gold, are made in London, England, and are available to you from fresh stock held at Polyscience’s warehouses in Pennsylvania and Germany. LR resins are a blend of hydrophilic monomers which exhibit low viscosity for rapid and thorough penetration. Sections may be cut at 1-5µ or ultra thin for EM work. Stable for 1 year when stored at 4° C, these very low viscosity (8cps) embedding media rapidly penetrate tissue due to their hydrophilic nature.

In Europe Only - L.R. White is sold in three different grades: soft, medium and hard. All grades can be obtained in either catalyzed or uncatalyzed form.
