20110020195 | SAMPLING AND DISPENSING DEVICE - The present invention relates to a device and method for easy collection, dilution, mixing and dispensing of a liquid specimen in a self-contained system. The present invention can be used in combination with numerous testing means for performing chemical, biochemical or biomedical qualitative or quantitative assays in the field of both clinical and hygiene testing. | 01-27-2011 |
20120201726 | REAGENT PREPARATION AND DISPENSING DEVICE AND METHODS FOR THE SAME - A reagent preparation and dispensing device includes a body. A reagent reservoir containing a reagent is disposed within the body. A solution reservoir containing a solution is disposed within the body. The device further includes an activator movably coupled with the body to open the reagent reservoir and the solution reservoir. The activator is operable to mix the solution with the reagent to form a reagent mixture. A dispensing reservoir tip is coupled with the body. The dispensing reservoir tip is sized and shaped to dispense the reagent mixture from the device. | 08-09-2012 |
20130195734 | REAGENT BOTTLE - A reagent bottle includes a reservoir adapted to contain a reagent, a pipette tip defining a fluid channel extending into the reservoir and a resilient seal fixedly disposed within the reservoir and surrounding the pipette tip, the seal functioning to reduce reagent loss when the pipette tip is withdrawn from the reagent bottle. The fluid channel of the pipette tip is defined by the pipette tip being in direct fluid communication, or interrupted fluid communication, with the exterior of the reagent bottle, the pipette tip being directly or indirectly engageable through a fluid-tight fitting with a pipette. A base member of the reagent bottle is adapted for selective engagement with one or more rotation pin and has an indexing feature for properly aligning the reagent bottle within an automated system. The base member adapted for selective engagement with one or more spring pins for raising and lowering the reagent bottle. | 08-01-2013 |
20130243665 | SAMPLER - Disclosed therein is a sampler. The sampler includes: a chamber accommodating a fluid or solid reagent therein and being sealed at both ends with penetrable films; a tube joined with the chamber at one side, the tube having a hollow portion therein; and a movable bar having a tip which is formed at one end and has a specimen extracting portion, the tip being guided and moved through a hollow portion, the tip being adapted for mixing the specimen extracted by the specimen extracting portion with the reagent so as to form a diluted solution while penetrating through one end of the chamber and adapted for quantitatively discharging out the diluted solution while penetrating through the other end of the chamber. | 09-19-2013 |
20140341787 | Mechanically Actuated Vacuum Controlled Fluid Collection - A mechanically-actuated vacuum-controlled fluid collection system includes a mechanically-actuated vacuum controller (MAVC) to draw fluid into a chamber through the opening to the chamber. The system may include a releasable seal to seal the opening, and the MAVC may include a spring-loaded plunger to create a vacuum within the chamber when sealed. The system includes multiple fluid chambers, and may further include a single actuator or multiple corresponding actuators. The system may be configured to add a pre-loadable reagent to fluid drawn into the one or more chambers, and may be configured to add the reagent in proportion to a volume of the fluid. The system may be controllable to release collected fluid to another device, such as for assay and/or transport. The system may be configured to draw a liquid biological sample such as urine, and may include a fluid interface to draw fluid from a biological sample container. | 11-20-2014 |
20150125364 | REAGENT PREPARATION ASSEMBLY - A reagent preparation assembly includes a body and a reaction chamber adjacent the body, the reaction chamber includes a reagent therein, such as a lyophilized reagent. An access port extends into the reaction chamber, and the access port is configured to receive an instrument. A seal extends across a portion of the reaction chamber and the access port. A reconstitution assembly is movably coupled with the body. The reconstitution assembly includes a plunger, a syringe and a piston. The plunger is movably coupled with the body. The syringe is selectively engaged with the plunger. The syringe includes a solution reservoir containing a solution, and movement of the syringe pierces the seal. The piston is selectively engaged with the plunger, and the piston is movably coupled within the syringe. Movement of the piston pushes the solution into the reaction chamber. | 05-07-2015 |
20150375223 | Disposable Tip for pricking septum of a sample vial for sample preparation and/or analysis. - This invention relates to a disposable pipette tip or tube designed to perform biological or chemical sample preparation, purification or separation where the samples are in a closed bottle with a lid with septum or membrane. In an automatic sampler for HPLC or Gas chromatography, septum closed vials are used to prevent samples from drying out or evaporating during the analytical process. The auto sampler needles are used to prick the septum at the vial to get the sample out for injecting in injector for the analysis. The same needle takes the samples from each vial, and therefore a contamination of the samples is possible. | 12-31-2015 |
