LR White™ Resin System
This one step single component acrylic embedding resin system has many advantages, its ultra low viscosity, only 8 cps, is almost like that of water and will infiltrate just about any type of sample. Even large blocks impregnate surprisingly fast. Another feature is convenience since one can do both TEM and LM sectioning from the same block.

this product was terrific in allowing me to properly embed my samples.

This one step single component acrylic embedding resin system has many advantages, its ultra low viscosity, only 8 cps, is almost like that of water and will infiltrate just about any type of sample. Even large blocks impregnate surprisingly fast. Another feature is convenience since one can do both TEM and LM sectioning from the same block.
Polymerization is started either by heat or when the need to preserve the sample's antigenicity is paramount, then also by a low temperature UV cure. One characteristic of the cured block is that sections tend to be quite hydrophilic.
Polymerization:
All three resin grades can be polymerized either chemically, at low temperature using UV irradiation at 365 nm, or by elevated temperatures, either by conventional oven or microwave techniques. Note that this resin system is not compatible with the use of acetone, since the presence of any ketone will inhibit polymerization.
