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.
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.
