Abstract

Um einen Probeträger weiterzuentwickeln, schlägt die Erfindung einen Probeträger mit mindestens einem Flüssigkeitskanal vor, wobei mehrere Flüssigkeitskanäle in einen ringartigen beispielsweise sechseckigen, Entlüftungskanal münden.
Dies hat den Vorteil, dass bei einer Verstopfung im Entlüftungskanal die Entlüftung über eine andere Wegstrecke erfolgen kann.

Figure 00000001
In order to further develop a sample carrier, the invention proposes a sample carrier with at least one fluid channel, with several fluid channels opening into an annular, for example, hexagonal, ventilation channel.
This has the advantage that in the event of a blockage in the venting channel, the venting can take place via a different path.
