The invention provides for a medical system (700) for determining a quantity of an analyte (602, 602') in a blood sample (600) using a cartridge (100). The medical instrument comprises the cartridge. The cartridge is operable for being spun around a rotational axis (102), wherein the cartridge comprises: an inlet (108) for receiving the blood sample; a blood separation chamber (118) for separating blood plasma from the blood sample, wherein the blood separation chamber is fluidically connected to the inlet; a processing chamber (124) containing at least one reagent comprising at least one specific binding partner (611) which is operable to bind to the analyte to form at least one analyte specific binding partner complex; a first valve structure (122) connecting the blood separation chamber to the processing chamber; a measurement structure (130) for enabling measurement of the quantity of the analyte, wherein the measurement structure comprises a chromatographic membrane (134), wherein the chromatographic membrane comprises an immobilized binding partner (620) for direct or indirect binding of the analyte or the at least one analyte specific binding partner complex, wherein the measurement structure further comprises an absorbent structure (132), wherein the absorbent structure is nearer to the rotational axis than the membrane; a second valve structure (128) connecting the processing chamber to the measurement structure; and a fluid chamber (136, 136') filled with a washing buffer (1202), wherein the fluid chamber is fluidically connected to the measurement structure, wherein a seal keeps the washing buffer with the fluid chamber.

Systems and methods for continuous flow polymerase chain reaction (PCR) are provided. The system comprises an injector, a mixer, a coalescer, a droplet generator, a detector, a digital PCR system, and a controller. The injector takes in a sample, partitions the sample into sample aliquots, dispenses waste, and sends the aliquot to the mixer. The mixer mixes the aliquot with a PCR master mix and diluting water, and sends the mixture (separated by an immiscible oil) to the coalescer. The coalescer coalesces the mixture with primers dispensed from a cassette, dispenses waste, and sends the reaction mixture (separated by an immiscible oil) to the droplet generator. The droplet generator converts the sample mixture into an emulsion where aqueous droplets are maintained inside of an immiscible oil phase and dispenses droplets to the digital PCR system. The digital PCR system amplifies target DNAs in the droplets.

A multi-well fluid container that includes a container body is provided for use in an in vitro diagnostics automation system. The container body includes a first well having a first well size configured to hold a first fluid and an openable first well closure that covers a first well opening. The first well opening provides access to the first fluid in the first well when the openable first well closure is opened. The container body also includes a second well having a second well size configured to hold a second fluid and having an openable second well closure that covers a second well opening. The second well opening provides access to the second fluid in the second well when the openable second well closure is opened. The first well size of the first well is different than the second well size of the second well.
摘要:
A method and apparatus for locating and selecting a colony of microorganisms on a culture dish and identifying microorganisms in said selected colony using MALDI. The method comprises the automated steps of locating and selecting a colony of microorganisms on a culture dish; obtaining a sample of said selected colony of microorganisms; depositing at least some of said sample of said selected colony of microorganisms on a target plate; and transferring said target plate with said sample in an apparatus for performing MALDI for identification of said sample of said selected colony of microorganisms. A sample of a colony of microorganisms is automatically deposited on a depositing spot such that the sample covers at most approximately half of said one of the depositing spots of the target plate. A suspension of a sample of microorganisms is automatically prepared by automatically picking the sample with a picking tool and submerging the picking tool with said sample in a suspension, after which the picking tool is vibrated in vertical sense only to release the sample from the picking tool.
