Abstract:
A small sample cup rack adapter having a spring biased plunger moveably disposed within a generally cylindrical outer body, with the plunger adapted to support a small sample cup within the outer body. After initial contact between an aspiration probe and the bottom of the small sample cup, the probe may be lowered an additional distance, minimizing the "dead volume" of sample.
Abstract:
A tube holder (10) is disclosed which comprises a web portion (12) having a plurality of apertures (26, 28, 30), and a base portion (14) disposed relative to the web portion (12) such that the apertures (26, 28, 30) are aligned relative to the base portion (14). The base portion (14) is configured such that a distance between the base portion (14) and the web portion (12) at one of the apertures (26, 28, 30) is different to a distance between the base portion (14) and the web portion (12) at another one of the apertures (26, 28, 30) so that tubes of differing lengths can be accommodated in the tube holder (10).
Abstract:
A multivolume pipette (1) is provided. In an exemplary embodiment, the multivolume pipette includes a pipette body (50) , a piston (3) disposed within the pipette body, a first chamber (7) , a second chamber (8) , and a valve F (13) . The first chamber and the second chamber are defined at least in part by an inner wall (52) of the pipette body and the piston. The valve is capable of placing the second chamber in fluid communication with an external environment to provide a first volume range of the multivolume pipette. The valve is also capable of placing the second chamber in fluid communication with the first chamber to provide a second volume range of the multivolume pipette.
Abstract:
A self-contained sampling probe characterized by a drive module and a syringe module removably coupled coaxially to the drive module to allow for different syringe modules to be interchangeably coupled to the drive module. The coupling is effected by quick connect and disconnect devices, and the syringe module may carry an identifier. The probe is engageable by a gripper or insertable in an interface device, both of which provide for communication of the probe with other system components.
Abstract:
A plurality of container assemblies are provided. Each container assembly has substantially identical external dimensions. However, the internal volumes of certain container assemblies differ from the internal volumes of other container assemblies. The container assemblies are configured in accordance with the required volume of material to be collected or maintained in the respective container assemblies and to enable uniform head spaces despite the different volumes of materials in the respective container assemblies. Each container assembly may have an inner container and an outer container. The inner and outer containers may be assembled together or formed integrally by molding.
Abstract:
The invention relates to a temperature-regulating block for laboratory thermostats. Said block comprises receivers on a receiver side to pick up the areas in containers filled with sample liquids having large area contacts and at least two temperature-regulating devices which conduct heat by contact to the temperature-regulating block to produce different temperatures in different sections of the temperature-regulating block. Said block is further characterized in that the temperature-regulating devices are in contact in a large area with adjacent limiting fields of the contact side lying opposite the receiving side of the temperature-regulating block.
Abstract:
Microarray slide holders for loading multiple microarray slides into a microscope system are disclosed. An apparatus for simultaneous microengraving and imaging of microwell arrays is disclosed. Also disclosed is a liquid run-off tray for simultaneous processing of multiple microarray slides.
Abstract:
A multi-well test plate assembly comprises a base member (2) with at least one opening (3) for receiving and housing at least a portion (1A, 1B) of a well strip (1), and at least one first insert member (21) arranged to fit into the opening, for supporting the portion (1A, 1B) of the well strip in the opening. This assembly makes it possible to process samples in portions of a well strip, such as in a portion with four well strips divided off a well strip with eight wells, with the portion of the well strip kept in a desired position in relation to the edges of the base member. Also disclosed are a method for adaptation of a well strip for use in the assembly, a method of preparing a test plate for analysis of at least one sample, and use of the multi-well test plate assembly for sample analysis.
Abstract:
A thermal cycler system for use with a sample holder (20) configured to receive a plurality of samples includes a sample block (14) having an upstanding peripheral side wall and being configured to receive the sample holder (20) and an adaptor (28) having an upstanding peripheral side wall configured to be positioned about the peripheral side wall of the sample block (14). When the peripheral side wall of the adaptor (28) is positioned about the peripheral side wall of the sample block (14) and the sample holder (20) is received in the sample block, the peripheral side wall of the adaptor (28) extends in an upward direction toward the sample holder (20).
Abstract:
The invention consists of an assembly of a reaction block a holder that contains arrays of vials. The vials can contain one or more of reagents, catalysts, and solvents for carrying out the series of chemical reactions.
