<p>I recently had a graduate student request 100% absolute ethanol to use for preserving tissue samples (fish muscle and/or fins). We routinely use 95% ethanol (and all tissue samples are then stored in a -80 freezer); however, the student is adamant that 100%
is the only preservative that is acceptable for tissue preservation. Does anyone have an opinion on 95% versus 100% ethanol for tissue preservation? There is a very steep price difference between the two fluids, and my understanding is that 95% ethanol preserves
tissues just as well as 100%.</p>
<p> </p>
<p>Thanks,</p>
