LONG-TERM PRESERVATION: Once specimens are fully fixed(they should be well hardened and rigid) they can be transferred for long-term storage in alcohol, or wrapped for shipment to a museum. Formalin should be decanted off(this formalin can be reused but it is advisable to add enough full strength formalin to bring the dilution back to 10% for future use). Specimens should be rinsed in water a few times to remove excess formalin, and then transferred to and stored in 70% ethanol, or 50% isopropyl alcohol. If alcohol is not available for long-term storage, specimens can be stored in formalin. If formalin storage is the only option then care should be taken to ensure that the formalin is well buffered and maintair at neutral pH
SHIPMENT: For shipment of formalin fixed specimens the following procedure is recommended: Specimens should be soaked in water overnight to remove all excess formalin. Strips of cheese cloth, muslin, or loose weave cotton should be dipped in water and excess water squeezed out so that the strips are moist but not dripping wet. Specimens should then be wrapped in the damp material so that each specimen is covered and protected. The material covered specimens should then be place in a plastic bag, along with a clean label O noting the field site number. The plastic bag should be tightly sealed and placed within another plastic bag to ensure that Carefully the specimens remain moist. Once packed the specimens may be boxed and shipped. Fully fixed specimens that remain damp may safely be stored for at least a month, although the sooner they can be unpacked, sorted and preserved ir alcohol the better. Different species captured at the same site can be fixed and stored together but do not to pack the jar too fully.
