PIPETTE
A pipette includes a capillary, a pressure chamber, a drive unit, and a control unit. The capillary has a first end and a second end that are two ends in a length direction and that are open. The pressure chamber communicates with an inside of the capillary via the second end. The drive unit changes a volume of the pressure chamber. The control unit controls the drive unit. The control unit outputs a vibrational movement signal that drives the drive unit so that a liquid moves from a mid-position in the capillary to a finish position that is located closer to the second end than the mid-position. The vibrational movement signal has a waveform that drives the drive unit so that the volume of the pressure chamber alternately increases and decreases repeatedly.
CAP HAVING A RIBBED INNER SURFACE
A cap having a lower portion, an upper portion with an opening formed therein, and a plurality of longitudinally oriented ribs disposed on an inner surface of the cap. The inner surface of the cap is defined by the opening formed in the upper portion of the cap, and each rib is associated with a concave recess disposed directly opposite the rib on an outer surface of the upper portion of the cap. The recess extends along at least part of the length of the rib.
SAMPLING DEVICE FOR BIOLOGICAL SPECIMEN
The present invention is directed to a sampling device for the collection and isolation of a biological specimen from a sample or from a location. The sampling device comprises a swab tip and a support body wherein the support body has a hollow conformation with a first end and a second end and wherein said first end is in fluid connection with the internal surface of the swab tip. Typical for the present sampling device is that the swab tip comprises a filter material with a pore size that decreases from the external surface of the swab tip to the internal surface of the swab tip. The invention further also discloses the use of said sampling device and a method for the collection and isolation of a biological specimen.
LATERAL FLOW IMMUNOASSAY DEVICE
A lateral flow immunoassay device includes a porous test strip, a sampling channel having an inlet at a first end to receive a biomarker and an outlet at a second end, opposite the first end, the outlet communicating with the test strip. The sampling channel has an air vent opening at or adjacent the second end thereof, and a diluent reservoir having an outlet communicating with the test strip. The outlet of the sampling channel and the outlet of the diluent reservoir are sealed by a common removable seal to prevent communication between the sampling channel and the test strip, and the diluent reservoir and the test strip, until the seal is removed.
Pretreatment method for specimen held in microchannel, pretreatment apparatus for performing pretreat method, and analysis system provided with pretreatment apparatus
A pretreatment apparatus includes a pretreatment container placement section where a pretreatment container which is housing a specimen holding member including a microchannel for holding a specimen is placed; a carrying mechanism for carrying the pretreatment container that is placed at the pretreatment container placement section; and a pretreatment section including a port where the pretreatment container that is carried by the carrying mechanism is placed, the pretreatment section being configured to perform pretreatment including a shaking process of shaking the pretreatment container to extract the specimen from the specimen holding member in the pretreatment container that is placed in the port.
Vaporizer Device Microfluidic Systems and Apparatuses
Microfluidic features regulate the flow of fluids in a cartridge for a vaporizer device. The microfluidic features prevent leaks of liquid vaporizable material and enhance the functioning of the cartridge when there is a differential pressure between a storage chamber containing the liquid vaporizable material and ambient conditions outside the cartridge. Related systems, apparatuses, and processes, are also described.
SYSTEMS AND METHODS OF SAMPLE DEPOSITING AND TESTING
The present application is generally directed to systems, methods, and devices for diagnostics for sensing and/or identifying pathogens, genomic materials, proteins, and/or other small molecules or biomarkers, for example, using loop-mediated isothermal amplification (LAMP). Some implementations include additional improvements, such as improvements to sample and reagent mixing, sample deposition, and compensation of inhibitors in the sample. Also disclosed herein are nucleic acid primers for use in the sensitive and specific detection of pathogens in biological samples by LAMP, which may be performed in the devices disclosed herein. The biological samples may be derived from patients including humans, plants, food, soil, contaminated surfaces, or animals such as livestock.
Blood Sample Management Using Open Cell Foam
A specimen mixing and transfer device adapted to receive a sample is disclosed. The specimen mixing and transfer device includes a housing, a material including pores that is disposed within the housing, and a dry anticoagulant powder within the pores of the material. In one embodiment, the material is a sponge material. In other embodiments, the material is an open cell foam. In one embodiment, the material is treated with an anticoagulant to form a dry anticoagulant powder finely distributed throughout the pores of the material. A blood sample may be received within the specimen mixing and transfer device. The blood sample is exposed to and mixes with the anticoagulant powder while passing through the material.
Particle analysis in an acoustic cytometer
The present invention is a method and apparatus for acoustically manipulating one or more particles.
