Abstract:
1. A container assembly for storing a biological sample, said assembly comprising: a container having a bottom, a side and an open top end, said container having a dimension to contain a volume of a reagent sufficient to treat a biological sample; a closure cap for coupling to said open top end of said container; and a sample holder coupled to said cap and being positioned to be received in said container, said sample holder having an internal cavity with a dimension for receiving a biological sample, said sample holder having a plurality of fluid openings into said cavity to enable free flow of said reagent into said cavity while retaining said biological sample in said cavity, said sample holder having a dimension to fit between said bottom and side of said container and said cap and to immerse said cavity in said reagent, said sample holder including a base member having a width equal to or greater than a width of said internal cavity to displace a predetermined portion of said reagent in said container and to reduce a head space above said reagent in said container and to maintain said internal cavity of said sample holder immersed in said reagent, said cavity of said sample holder having a volume to limit the size of said biological sample to maintain a predetermined ratio of an amount of said biological sample to an amount of said reagent to treat said biological sample.
