Device and a method for separating liquid samples
First Claim
1. A device for separating a liquid sample, comprising:
- at least one sample container (12) having an inlet opening (16) and an outlet spout (24) integral with said sample container (12) at its bottom wall (20), said outlet spout (24) joining and enclosing an outlet opening (22) between which inlet opening (16) and outlet opening (22) a separation layer (28) is arranged,at least one collecting container (32) for the liquid emerging through said outlet opening (22), having rim (38) surrounding an opening (36) therein, rim (38) of said collecting container (32) abutting said sample container (12) by at least one of said outlet spout (24) and said bottom wall (20) of said sample container (12) to prevent escape of liquid and aerosols from said collecting container (32),wherein said collecting container (32) comprises tubular wall (37) in which is located channel (39) to provide a non-airtight sealing between said sample container (12) and said collecting container (32), said outlet spout (24) extending through said opening (36) of said collecting container (32) into said collecting container (32).

Abstract
A device (10) for separating liquid samples has a sample container (12), bottom wall (20) of which has an outlet opening (22) provided therein. The outlet opening (22) is joined by an outlet spout (24) extending in the axial direction of the sample container (12). On bottom wall (20) there is a separation layer (28). Below sample container (12), a collecting container (32) is arranged abutting sample container (12) such that an exchange of air between the interior of the collecting chamber (32) and the environment is possible, yet an escape of liquid is largely inhibited. The contact surface between collecting chamber (32) and sample container (12) and end (26) of the outlet spout (24) through which the liquid is discharged, are axially spaced apart.

1. A device for separating a liquid sample, comprising:
-
at least one sample container (12) having an inlet opening (16) and an outlet spout (24) integral with said sample container (12) at its bottom wall (20), said outlet spout (24) joining and enclosing an outlet opening (22) between which inlet opening (16) and outlet opening (22) a separation layer (28) is arranged, at least one collecting container (32) for the liquid emerging through said outlet opening (22), having rim (38) surrounding an opening (36) therein, rim (38) of said collecting container (32) abutting said sample container (12) by at least one of said outlet spout (24) and said bottom wall (20) of said sample container (12) to prevent escape of liquid and aerosols from said collecting container (32), wherein said collecting container (32) comprises tubular wall (37) in which is located channel (39) to provide a non-airtight sealing between said sample container (12) and said collecting container (32), said outlet spout (24) extending through said opening (36) of said collecting container (32) into said collecting container (32).

3. A device for separating a liquid sample, comprising:
-
at least one sample container (12) having an inlet opening (16) and an outlet spout (24) integral with said sample container (12), said outlet spout (24) joining and enclosing an outlet opening (22) between which inlet opening (16) and outlet opening (22) a separation layer (28) is arranged, at least one collecting container (32) for the liquid emerging through said outlet opening (22), having an opening (36) therein, said collecting container (32) having an abutting portion for abutting at least one of said outlet spout (24) and said sample container (12) by the rim (38) of said collecting container (32) at its opening (36), wherein said abutting portion of collecting container (32) is provided with a ring of porous material (47) permeable to air which prevents the escape of liquid and aerosols, and provides a non-airtight sealing.

4. A device for separating a liquid sample, comprising:
-
at least one sample container (12) having an inlet opening (16) and an outlet spout (24) integral with said sample container (12), said outlet spout (24) joining and enclosing an outlet opening (22) in bottom wall (20), between which inlet opening (16) and outlet opening (22) a separation layer (28) is arranged, at least one collecting container (32) for the liquid emerging through said outlet opening (22), having an opening (36) therein, said collecting container (32) abutting said sample container (12) by at least one of said outlet spout (24) and said bottom wall (20) of said sample container (12) by the rim (38) of said collecting container (32) at its opening (36), which provides a means for a non-airtight sealing between rim (38) of opening (36) of collecting container (32), and at least one of outlet spout (24) and bottom wall (20) of sample container (12) which allows for an exchange of air between the interior of collecting container (32) and the environment, and prevents escape of liquid or aerosols from said collecting container (32), said outlet spout (24) extending through said opening (36) of said collecting container (32) into said collecting container (32). - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
