Abstract
In an apparatus used for perfusion-treating objects within a defined treatment area of a liquid bath, the apparatus having a ring having a lower edge which is sealingly placeable on the bottom of the liquid bath and an interior for connection to a liquid conveying device. The ring includes a holding member for receiving an inlet member of the liquid conveying device, or a wall having at least one wall chamber which communicates with the holding member on the ring and with the interior of the ring.
Claims28
A device for treating objects within a defined treatment area of a liquid bath, comprising:
- a ring having a wall portion, a lower edge portion, an upper edge portion and an interior space, said lower edge portion being capable of being sealingly positioned on the bottom of said liquid bath to form said defined treatment area;
- a holding member connected to said upper edge portion and in communication with said interior space, said holding member being capable of engaging a tip-like inlet member of a liquid conveying device in a non-positive, detachable manner;
- wherein a liquid in said liquid conveying device can be discharged into said defined treatment area of said liquid bath when said liquid conveying device is engaged with said holding member, said defined treatment area being formed in said interior space of said ring by sealingly positioning said lower edge portion on said bottom of said liquid bath,
- wherein said wall portion comprises a soft elastic material and wherein said holding member is formed by sealingly piercing said wall with said inlet member.
A device for treating objects within a defined treatment area of a liquid bath, comprising:
- a ring having a lower edge portion, an upper edge portion, an interior space and a wall portion with an interior chamber in communication with said interior space, said lower edge portion being capable of being sealingly positioned on the bottom of said liquid bath to form said defined treatment area;
- a holding member positioned on said upper edge portion and in communication with said interior chamber, said holding member being capable of engaging a tip-like inlet member of a liquid conveying device in a non-positive, detachable manner;
- wherein a liquid in said liquid conveying device can be discharged into said defined treatment area through said interior chamber when said inlet member is engaged with said holding member, said defined treatment area being formed in said interior space of said ring by sealingly positioning said lower edge portion on said bottom of said liquid bath,
- wherein said lower edge portion comprises a soft elastic coating.
A mounting ring for a pipette having a tip-like end portion, comprising a ring surrounding said tip-like end portion and having a wall portion, a lower edge portion, an upper edge portion and an interior space, said lower edge portion facing away from said tip-like end portion and being capable of being sealingly positioned on the bottom of said liquid bath to form said defined treatment area,
- said ring having a holding member being positioned in said interior space of said ring and connected to said upper edge portion, said holding member being fixed to said tip-like end portion;
- wherein a liquid in said pipette can be discharged into said defined treatment area of said liquid bath, said defined treatment area being formed in said interior space of said ring by sealingly positioning said lower edge portion on said bottom of said liquid bath.
A method for treating objects within a defined treatment area of a liquid bath with a perfusing liquid flow conveyed by a liquid conveying device having an end portion from which liquid is conveyed, the steps of which comprise:
- positioning an object treating device sealingly on said liquid bath to form said defined treatment area, said object treating device comprising a ring having a wall portion made of a soft elastic material, a lower edge portion, an upper edge portion and an interior space, said lower edge portion being capable of being sealingly positioned on the bottom of said liquid bath to form said defined treatment area, and a holding member connected to said upper edge portion and in communication with said interior space, said holding member being capable of engaging said end portion of said liquid conveying device in a non-positive, detachable manner;
- engaging said end portion of said liquid conveying device with said holding member by sealingly piercing said wall with said end portion, said liquid conveying device containing a perfusion liquid;
- and
- discharging said perfusion liquid from said liquid conveying device into said defined treatment area.
A method for treating objects within a defined treatment area of a liquid bath with a perfusing liquid flow conveyed by a liquid conveying device having an end portion from which liquid is conveyed, the steps of which comprise:
- positioning an object treating device sealingly on said liquid bath to form said defined treatment area, said object treating device comprising a ring having a wall portion, a lower edge portion with a soft elastic coating, an upper edge portion and an interior space, said lower edge portion being capable of being sealingly positioned on the bottom of said liquid bath to form said defined treatment area, and a holding member being positioned on said upper edge portion and in communication with said interior space, said holding member being capable of engaging said end portion of said liquid conveying device in a non-positive, detachable manner;
- engaging said end portion of said liquid conveying device with said holding member, said liquid conveying device containing a perfusion liquid;
- and
- discharging said perfusion liquid from said conveying device into said defined treatment area.
A method for treating objects within a defined treatment area of a liquid bath with a perfusing liquid flow conveyed by a liquid conveying device having an end portion from which liquid is conveyed, the steps of which comprise:
- positioning an object treating device sealingly on said liquid bath to form said defined treatment area, said object treating device comprising a ring having a wall portion, a lower edge portion with a soft elastic coating, an upper edge portion and an interior space, said lower edge portion being capable of being sealingly positioned on the bottom of said liquid bath to form said defined treatment area, and a holding member being positioned in said interior chamber of said ring, said holding member being capable of engaging said end portion of said liquid conveying device in a non-positive, detachable manner;
- engaging said end portion of said liquid conveying device with said holding member, said liquid conveying device containing a perfusion liquid;
- and
- discharging said perfusion liquid from said liquid conveying device into said defined treatment area.
A device for treating objects within a defined treatment area of a liquid bath, comprising:
- a ring having a wall portion, a lower edge portion, an upper edge portion and an interior space, said lower edge portion being capable of being sealingly positioned on the bottom of said liquid bath to form said defined treatment area;
- a holding member connected to said upper edge portion and in communication with said interior space, said holding member being capable of engaging a tip-like inlet member of a liquid conveying device in a non-positive, detachable manner;
- wherein a liquid in said liquid conveying device can be discharged into said defined treatment area of said liquid bath when said liquid conveying device is engaged with said holding member, said defined treatment area being formed in said interior space of said ring by sealingly positioning said lower edge portion on said bottom of said liquid bath,
- wherein said holding member is positioned in said interior space of said ring.
