Vials for tissue samples

The development of new analytical techniques has made it possible to extract and study the DNA and other molecules from specimens.  Small samples of tissue (muscle, liver, heart) are taken from carcasses during preparation.  It is also possible to obtain DNA from older specimens that have been preserved for hundreds of years. 

Tissues are a steadily increasing component of the Ornithology colleciton. Samples are usually store in vials, such as these, in ultra deep freezers at -80°C, or else in ethanol.
