Tube tray for secondary tubes, secondary tube handling module, and method of handling secondary tubes in an automated processing system

A secondary tube handling module for an automated processing system for automatically processing a biological sample, provided as a component arranged inside a housing of the automated processing system, wherein:

• the secondary tube handling module is adapted to hold at least one secondary tube tray comprising a base module and a secondary tube insert, the secondary tube insert being adapted for holding a plurality of secondary tubes in parallel, the secondary tube insert being inserted into said base module, wherein the base module comprises a substantially closed bottom side with at least one discharge opening for discharging secondary tubes, the secondary tube insert is a hollow body with at least one insert opening in its bottom side, and the secondary tube insert comprises a blocking mechanism in the form of a blocking bar movably arranged on an inside of the secondary tube insert, said blocking mechanism blocking the at least one discharge opening in the bottom side of the base module when the blocking mechanism is not moved from a closed state to an open state, wherein the blocking mechanism is adapted to be openable from outside of the base module;
• the secondary tube handling module comprises a separator for extraction of secondary tubes from the secondary tube insert of the secondary tube tray, the separator comprising a tilting mechanism for tilting the secondary tube tray about a lateral axis;
• the secondary tube handling module comprises at least one blocking mechanism actuating member for actuating the blocking mechanism to block/unblock the discharge opening in the bottom side of the base module;
• and
• the secondary tube tray and said blocking mechanism actuating member are movable relative to each other by means of said tilting mechanism to move the blocking mechanism actuating member through the discharge opening in the bottom side of the base module and through the insert opening in the bottom side of the secondary tube insert, to engage with the blocking mechanism.
