A kit for centrifugal isolation of a fraction of interest from a multi-component composition according to density, comprising: a separation chamber (200) having an inlet (210) for introducing the multi-component composition and a base through-hole (220); characterized in that the separation chamber (200) comprises: an inlet section (211) communicating with the inlet (210), a base section (212) communicating with the base through-hole (220), wherein the inlet section (211) and the base section (212) communicate with each other via a necked duct (230) for detaching the inlet section (211) and the base section (212) at the necked duct (230), wherein the separation chamber (200) has a form of a syringe in which the inlet of the separation chamber (200) is connectable with an extension nozzle or needle (215) for drawing the multi-component composition, and wherein the kit further comprises a plunger (240) for embedding and being slidably moved within the base section (212) of the separation chamber (200), wherein the plunger (240) comprises a plunger handle (242), removably attached to a plunger base (241), for sealing the base through-hole (220), and wherein the diameter of the necked duct (230) lumen is selected so as to maintain the multi-component composition, after detaching the inlet section (211) and the base section (212) at the necked duct (230), in the inlet section (211), by virtue of a partial negative pressure created within the inlet section (211) when the inlet (210) is sealed.

A dosimetry device includes a first chamber formed on a substrate with a first decomposable barrier sensitive to radiation and a first chemical component. A second chamber is formed on the substrate in proximity of the first chamber and includes a second decomposable barrier sensitive to radiation and a second chemical component. Upon a radiation event, decomposition of the first and second barriers of the first and second chambers permits a mixing of the first and second chemical components to cause a visible change of the dosimetry device.
