Product Description:
How long with they remain preserved?
As long as the original container seal is unbroken, specimens will remain usable indefinitely. If the seal on the specimen bag has been broken during transit, the shelf life is affected only slightly. Just close the bag with a rubber band or some other type of closure. Keep tightly sealed. Exposure to air will not cause decay, but specimens will gradually dry out. Between classroom sessions, return specimens to tightly closed plastic bag or airtight container.
What if they seem to dry out?
If specimens are to be dissected over an extended period of time, they can be remoistened with NASCO-Guard® Humectant Fluid (item numbers SB17218M, SB12631M, SB32395M, or SB32396M).
Can I use water to moisten the specimens?
No, do NOT add water. Do NOT add formaldehyde or any other preservative to NASCO-Guard® specimens. Your specimens are completely preserved and the addition of water or other preservatives might have undesirable effects on the specimens.
