Testing & Storing Nembutal The Storage of Liquid Nembutal
Veterinary liquid comes in sealed, sterile glass 100ml bottles. It is best not to disturb the seal on the bottle until it is needed.
Do not break the seal or decant the liquid into another container as this will expose the drug to the air. Store the original bottles in a cool dark place. Refrigeration is fine, but do not freeze as the bottle can break.
The liquid should be clear and colourless. Any coloration or precipitation of the liquid means that further testing and assay will be required.
Note about Nembutal capsules, tablets and long term storage
Note: Pharmaceutical grade Nembutal capsules or tablets are no longer produced. Those who have access to these drugs and are planning their use, should be aware that because of their age, these drugs are likely to have deteriorated, and should be tested.
Note: Previous editions of The Peaceful Pill eHandbook outlined a method of long-term storage that involved the conversion of the salt (sodium pentobarbital, CAS No 57-33-0 ) to the free acid (pentabarbital CAS No 76-74-4).
However, the success of long-term, vacuum-packing of the soluble salt has made this process unnecessary, and it has now been removed from the eHandbook.
