Product DescriptionTechnical DataMSDSDelivery & Returns
This is a hydrophilic acrylic resin of low viscosity (8 cps) available in three grades of hardness. The resin has wide application, being suitable for both light and electron microscopy. With appropriate fixation, the same specimen may be used for both techniques although the soft grade is not recommended for EM use. It may be thermally cured or cold cured using the accelerator. It has been successfully used for immunocytochemical and immunohistochemical techniques but it is not designed to be used at very low temperatures since the components begin to separate out at about -15°C. Its low viscosity makes it suitable for infiltrating decalcified bone and teeth.
LR White is available in either a convenient premixed and ready to use form, Catalysed LR White, or as a non-catalysed version. The uncatalysed version of LR resin does not need to be kept in a fridge and can be kept at room temperature in a dry place. 24 hours prior to use, simply add in the catalyst (9.9g of catalyst per 500ml of LR White), mix thoroughly and leave for 24 hours to ensure the catalyst has fully dissolved into the resin.
The catalysed version of LR White should be kept at 4°C or lower (air shipment or courier for export).
The resin is an irritant and the accelerator is toxic.
