The FORMALeasy® tube was specifically designed for small biopsy specimens collected with biopsy tongs. It is prefilled with 10% neutral buffered formalin.
The cap is made of a special polymer that allows the biopsy tongs to pass through it to release the sample inside the tube. Once this operation is completed, simply extract the instrument from the tube.
Thanks to its properties, the cap prevents the liquid from leaking out.
