[Nhcoll-l] FW: Glycerol as a safer alternative to ethanol for display specimens - Feedback from your practice?

[Callomon,Paul]

Another consideration is the optical clarity of glycerol versus ethanol, both initially and over time. These are display specimens, so it seems a good idea to ensure that whatever medium you use has full-spectrum visibility and is stable over time (and under lighting) in that regard. Also, exudates from the specimens (like lipids) might discolor different fluids to differing extents.
