Claim 12:
13. Method of connecting a combinable cavity tray (10) according to claim 1 or an assembly (100) of combinable cavity trays according to a pipetting apparatus with pipetting tubes (61), the method comprising:
inserting at least one pipetting tube (61) with its first end (62) in a cavity (20) of a first combinable cavity tray (11) through the opening (22) of the cavity (20) with a first force to achieve a friction fit between the at least one pipetting tube (61) and the first combinable cavity tray (11);
inserting at least one further pipetting tube (61) with its first end (62) in a cavity (20) of a second combinable cavity tray (12) through the opening (22) of the cavity (20) with a second force to achieve a friction fit between the at least one further pipetting tube (61) and the second combinable cavity tray (12);
positioning the first combinable cavity tray (11) connected to the at least one pipetting tube (61) and the second combinable cavity tray (12) connected to the at least one further pipetting tube (61) on a rigid base and further inserting the at least one pipetting tube (61) and the at least one further pipetting tube (61) in the cavities (20) with a third force being stronger than the first force and the second force to achieve a fluid-tight connection of the at least one pipetting tube (61) and the at least one further pipetting tube (61) to the cavities (20) and to in particular achieve assembling the first combinable cavity tray (11) and the second combinable cavity tray (12) to form an assembly (100) of combinable cavity trays (10).
