Transfer device for laboratory containers
View Patent ↗A device connects a storage container to a working reservoir for transferring a substance from the storage container to the working reservoir. The device includes a housing which is joined to the storage container with either a fixed connection or a coupling means. A passage opening is formed on the housing, and a shutter that is movably connected to the housing serves to close the passage opening. The shutter has a connector port for each working reservoir. The shutter moves in a rotary or sliding manner relative to the housing between an open position and a closed position. In the closed position, the passage opening is closed off by the shutter, and in the open position the interior space of the storage container is connected through the passage opening to the interior space of the working reservoir which is seated in the at least one connector port.
1. A device for transferring a substance from a storage container to a working reservoir, comprising:
a housing;
a fixed connection or a coupling means formed on the housing, through which the storage container is connected to the housing;
a passage opening formed on the housing, the passage opening communicated to an interior space of the connected storage container; and
a shutter, comprising a connector port adapted for seating the working reservoir, the shutter rotating or sliding relative to the housing from an open position to a closed position, such that:
in the open position, the shutter aligns the interior space of the storage container to a mouth of the working reservoir that is seated in the connector port, through the passage opening; and
in the closed position, the shutter offsets the mouth of the working reservoir from the passage opening.
2. The device of claim 1 , further comprising:
a device for inseparably locking the connector port into a seated connection with the working reservoir, when the shutter is in the open position.
3. The device of claim 2 , further comprising
a device for locking the shutter that immobilizes the shutter in the closed position when no working reservoir is connected to the connector port.
4. The device of claim 3 , wherein:
the shutter comprises at least two connector ports; and
the shutter locking device limits rotation or sliding of the shutter only as far as there are connector ports that are occupied by working reservoirs following each other in an uninterrupted sequence.
5. The device of claim 1 , wherein:
the coupling means is adapted to be non-releasably connected to the storage container; or
the device further comprises a storage container lock which locks up the coupling means.
6. The device of claim 1 , wherein:
the means for connecting the connector port to the working reservoir and the means for connecting the coupling means to the storage container are each selected from the group consisting of: a screw connection, a bayonet coupling connection, a snap engagement connection, and a plug-in connection.
7. The device of claim 1 , wherein:
the connector port has a standardized fitting design and is adaptable with an adapter for connecting a working reservoir with a non-standard working reservoir thereto.
8. The device of claim 1 , further comprising:
a chamber or a connector port for attaching a chamber, formed in the housing, the chamber being filled with a desiccant.
9. The device of claim 1 , further comprising:
a gas connector port arranged in the housing.
10. The device of claim 1 , further comprising:
a closure seal device for affixing a seal on a fill opening of the filled working reservoir; and/or
a closure device for putting a stopper plug on a fill opening of the filled working reservoir.
11. The transfer device of claim 1 , further comprising:
a spring element, co-acting with the connector port, to hold the working reservoir set into the connector port under tension against the housing.
12. The device of claim 1 , further comprising
a device for locking the shutter that immobilizes the shutter in the closed position when no working reservoir is connected to the connector port.
