초록 ▼

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.

대표청구항 ▼

A device for separating a liquid sample, comprising a sample container (12) having an inlet opening (16) and an outlet opening (22) between which a separation layer (28) is arranged, said sample container having a bottom wall (20) in which said outlet opening (22) is located, a collecting container (32), for liquid emerging through said outlet opening (22), having a tubular wall (37) and a rim (38) which defines an opening (36) therein, and an outlet spout (24) joining and enclosing said outlet opening (22), said sample container (12) having a unperforated collar (40) formed thereon that is a barrier for, and coaxially surrounds, said outlet spout (24), unperforated collar (40) being shorter than said outlet spout (24), said a perforated collar (40) being located within collecting container (32), and wherein said collecting container (32) abuts at least one of said sample container (12) and said outlet spout (24) adjacent to said rim (38), without providing an airtight sealing, and an end of said outlet spout (24) extending through said opening (36) of said collecting container (32) and into the same.
