Abstract: A container assembly for collecting amorphous specimens that includes a tube member, enclosed by a plastic bag and both these housed by two jacket members. Each jacket member has one porous plug inside. The jackets are urged together by a rubber band and the tube member is firmly sandwiched between the plug members. One of the jackets is longer than the other so that the former can be used as a test tube.

Abstract: A kit for collecting specimens that includes a trocar member 20 which is partially housed, at its ends, by jacket members 30 and 40 and rubber band 50 wrapped around jacket members 30 and 40. The first alternate embodiment includes trocar 30' which has a porous lateral wall or the lateral wall includes small apertures so that the moisture can escape thereby permitting a user to do an occult blood test. The second alternate embodiment corresponds to trocar 30" that includes larger apertures around its lateral wall. The second alternate embodiment is intended to be used in hystopathological procedures. A mixer member is coaxially mounted within either jacket member 30 or 40. A reagent is preferably stored in the other jacket not having the mixer member.
