SPI-Chem™ Water Soluble Embedding Media
Select from fine completely and also partially water soluble systems
Introduction:
Most embedding of samples today, for life science work, is done with various epoxy based
systems, which are preferred because of a combination of favorable factors: Ease of use,
low (relative) cost, and "moderate" on the scale of hazardous chemical exposures (relative
to the acrylics, for example). But all epoxy systems require a complete (usually alcohol)
dehydration which is not so terrible for those doing strictly structure and morphology,
but could be catastrophic for those doing delicate immuno reactions and immuno electron and
light microscope.
The ideal embedding media then would be one that did not require any dehydration, that the
wet sample could literally be plunged into the monomer and polymerized. Such systems are
called "completely water soluble" since absolutely no alcohol dehydration is needed.
Partially water soluble media are those systems where only a partial dehydration is required.
Such systems seem to be quite acceptable for many of the normal requirements but there does
seem to be a subset of samples, for example, bone and cartilage, that require the use of a
completely water soluble system.
