Apparatus for performing saturation analyses

Claim 1

A DEVICE SUITABLE FOR PERFORMING A SATURATION ANALYSIS IN WHICH BY THE USE OF A SEPARATING AGENT A RADIOACTIVE-SUBSTANCE BOUND TO A COMPETIVE BINDER IS SEPARATED FROM ITS UNBOUND FORM WHICH DEVICE COMPRISES A TUBULAR MEMBER OPEN AT BOTH ENDS AND CONTAINING IN A LOWER PART THE SEPARATING AG*NT AND CONTAINING IN AN UPPER PART A REACTION COMPARTMENT CONTAINING A RADIOACTIVE REAGENT, SAID REACTION COMPARTMENT BEING A CONTAINER CLOSED WITH RESPECT TO THE SEPARETING AGENT AND HAVING A NON-POROUS BOTTOM PORTION FACING THE SEPARATING AGENT WHICH MAY BE RENDERED PERMEABLE TO LIQUID AND SAID NON-POROUS BOTTOM PORTION INCLUDING A HYDROPHOBIC POROUS FILTER CAPABLE OF BEING MADE PERMEABLE TO LOQUID BY SHAKING OR BY PROVIDING A PRESSURE DIFFERENTIAL BETWEEN THE REACTION COMPARTMENT AND THE REMAINDER OF THE TUBULAR MEMBER.

Claim 2

A DEVICE SUITABLE FOR PERFORMING A SATURATION ANALYSIS IN WHICH BY THE USE OF A SEPARATING AGENT A RADIOACTIVE-SUBSTANCE BOUND TO A COMPETIVE BINDER IS SEPARATED FROM ITS UNBOUND FORM WHICH DEVICE COMPRISES A TUBULAR MEMBER OPEN AT BOTH ENDS AND CONTAINING IN A LOWER PART THE SEPARATING AG*NT AND CONTAINING IN AN UPPER PART A REACTION COMPARTMENT CONTAINING A RADIOACTIVE REAGENT, SAID REACTION COMPARTMENT BEING A CONTAINER CLOSED WITH RESPECT TO THE SEPARETING AGENT AND HAVING A NON-POROUS BOTTOM PORTION FACING THE SEPARATING AGENT WHICH MAY BE RENDERED PERMEABLE TO LIQUID AND SAID NON-POROUS BOTTOM PORTION INCLUDING A HYDROPHOBIC POROUS FILTER CAPABLE OF BEING MADE PERMEABLE TO LOQUID BY SHAKING OR BY PROVIDING A PRESSURE DIFFERENTIAL BETWEEN THE REACTION COMPARTMENT AND THE REMAINDER OF THE TUBULAR MEMBER.

Claim 3

A device suitable for performing a saturation analysis in which by the use of a separating agent a radioactive-substance bound to a competitive binder is separated from its unbound form which device comprises a tubular member open at both ends and containing in a lower part the separating agent and containing in an upper part a reaction compartment, said reaction compartment being a container closed with respect to the separating agent and having a non-porous bottom portion facing the separating agent which may be rendered permeable to liquid and said non-porous bottom portion being constituted by a layer of wax the melting point of which lies between 40*C and 100*C.

Claim 4

A device suitable for performing a saturation analysis in which by the use of a separating agent a radioactive-substance bound to a competitive binder is separated from its unbound form which device comprises a tubular member open at both ends and containing in a lower part the separating agent and containing in an upper part a reaction compartment, said reaction compartment being a container closed with respect to the separating agent and having a non-porous bottom portion facing the separating agent which may be rendered permeable to liquid and said non-porous bottom portion being constituted by a layer of wax the melting point of which lies between 40*C and 100*C.

Claim 5

A device suitable for performing a saturation analysis in which by use of a separating agent a radioactive-substance bound to a competitive binder is separated from its unbound form which device comprises a tubular member open at both ends and containing in a lower part the separating agent and in an upper part is provided with a reaction compartment, the upper part and the lower part of the tubular member being joined to one another by an intermediate member provided with a central bore and in which a slide is mounted displaceable in a direction at right angles to the axis of the bore so as to entirely close the bore in one extreme position and to entirely open the bore in the other extreme position.

Claim 6

A device suitable for performing a saturation analysis in which by use of a separating agent a radioactive-substance bound to a competitive binder is separated from its unbound form which device comprises a tubular member open at both ends and containing in a lower part the separating agent and in an upper part is provided with a reaction compartment, the upper part and the lower part of the tubular member being joined to one another by an intermediate member provided with a central bore and in which a slide is mounted displaceable in a direction at right angles to the axis of the bore so as to entirely close the bore in one extreme position and to entirely open the bore in the other extreme position.
