Any specimens that fit into a jar or vial may be "pickled" by using any of several different preservatives. Do not pack the specimens into the jar. The U.S. National Herbarium attempts to keep Formalin fixed, EtOH preserved (see below) portions of most specimens, with the exception of Corallines, which are kept in 3-5% Formalin. Most specimens are kept either in 4-dram (21 x 70 ml) shell vials inside canning jars, or in 20-ml scintillation vials with urea/ poly-seal cone caps, filled with the preservative.
