Poly/Bed® 812 Embedding Kit, with DMP-30
Poly/Bed® 812 for electron microscopy and histology
for studies requiring beam stability, low shrinkage and good contrast.
Epoxy formulations are lower in viscosity than Araldite formulations,
and hence provide better penetration into tissue samples. Instructions included.

"Spurr" Low Viscosity Kits
ERL 4221 has replaced ERL 4206. ERL 4221 has a higher viscosity than the previously used ERL 4206.
Spurr AR, 1969. A low-viscosity epoxy resin embedding medium for electron microscopy. J Ultrastruc Res, 26, p. 31.
Ellis, E Ann, Solutions to the Problem of Substitution of ERL 4221 for Vinyl Cyclohexene Dioxide in
Spurr Low Viscosity Embedding Formulations, Microscopy Today, V 14, No 4, July 2006
The Spurr Kit gives excellent penetration for tough materials particularly in the studies of botanical, mineral and
other hard biological specimens. When the mixture is kept at room temperature for 24 hours its viscosity will
increase to 140cP, as is the case with other resins. When fully formulated, the Spurr’s resin will store
in a deep-freeze for two months and at room temperature for two days. Curing is done at 70ºC for about 8
hours (see our Microwave system for significant time saving during epoxy processing).

Resin with initiator (BPO) packaged separately. Accelerator #18185 can be used for cold-cure (room temperature). Heat cure is 24 hours between 50°C and 65°C. Gelatin capsules are recommended for temperatures below 60°C. Tightly closed BEEM® Capsules and PTFE Molds with ACLAR® as cover (#10506 or #10508) work well at 65°C. Widely used because of excellent immunolabeling results. LR White is a polar, monomer polyhydroxylated aromatic acrylic resin (see PTFE Molds).
* LR White Soft is not recommended for electron microscopy. |

Sections from LR White appear "bumpy" in contrast to Epon resin sections. It is possible that
Epon links covalently to tissue proteins while LR White links more weakly. "LR White appears to act in
a manner similar to ice in a freeze-fractured specimen."17 A. Yamamoto and Y. Tashiro, using AFM, found
a strong relief surface on LR White sections, 3-4nm on average. Depressions ranged from 6 to 30nm. Protrusions
could be seen on the complimentary surface. Epon sections show relatively smooth surfaces.18 Micrographs appear
similar to freeze-etched images but scaled to nm instead of µm. Viscosity ~= 8cP
