LR White Embedding Kit

A very low viscosity (8cps), non-toxic resin, suitable for both Light and Electron Microscopy. LR White is a polar monomer polyhydroxylated aromatic acrylic resin. It can be cured by heat or by UV light. The uncatalyzed version has to be activated prior to use by adding the included catalyst.

Product Details

Description

Activation of uncatalyzed LR White resin

Prior to use LR White resin has to be activated by adding the catalyst (9.9g Benzoyl Peroxid). After adding incubate for 24 hours at RT. After activation store at 4°C. The shelf-life is about 1 year.

Non-activated LR White can be stored at RT with a longer shelf-life.

For detailed information please see 'Catalyst Information' data sheet.

 

Usage of the different grades

In general, resin grades differ in their ability to transmit cutting stresses from the resin to the fixed specimen. Thereby, chattering generated by the microtome while cutting can be minimized.

The hard grade is designed for stiff tissues and specimens such as highly cross-linked polymers and demineralized bone.

The medium grade is designed to span between hard and very soft specimens.

An example of a very soft specimen would be a fixed gelatinous material such as synovial fluid.

The difference between the grades is a combination of two properties: The hardness of the resin itself and its visco-elastic characteristics. This is achieved by a fair balance of cross-linking density and backbone plasticisation.
