== Alcohol Storage ==

Alcohol storage is an old and still widely used preservation method. If storing whole organisms, removal of the intestines is required. Proper storage can be achieved with 70%-90% purity alcohol or methylated spirit. To better preserve the DNA, sodium chloride (Common salt) can be added. 5% Glycerine also supposedly protects the specimen should an accident cause the alcohol to escape or evaporate. The container should be sealed and stored in a dark and cool place, such as a freezer.

The container's alcohol should be replaced at least once, a few weeks after immersion (Or whenever the liquid starts to turn darker or cloudy), as body fluids seep out and contaminate the alcohol. The above-mentioned additives should only be added after the replacement of the alcohol.

While alcohol preservation is very cheap and easy to do, both commercially and DIY (All it takes it some alcohol, a glass container and a freezer), it is overall a very poor preservation method, at least from the perspective of what cryonics tries to achieve: Under a microscopy, they degrade into mush after only a few months.

While biological specimens can be stored for many decades without exterior degradation (Einstein's brain and the Tasmanian Tiger "clone pup", the latter remaining integral after 130 years of alcohol storage), it only preserves macroscopic structure, and maybe enough genetic material to make a clone. Another, less significant issue, is the flammability of alcohol.
