The present disclosure provides methods for reducing the viscosity of a cell lysate or tissue lysate by: contacting the cell lysate or tissue lysate with a compressible and open-cell foam filter having a pore size from about 0.65 mm to about 1.22 mm, compressing the filter to recover the lysate absorbed in the filter, and collecting the filtered lysate; and also provides kits therefor.

A mixing device for operating biological, chemical or biochemical materials used in an assay includes a mixing member formed with a plurality of chambers, each having a sealable port provided along an edge of the mixing member. The mixing device also includes one or more compartments that are movable along the edge of the mixing member between selected ones of the sealed chambers. This compartment is operable to receive materials from and transfer materials between the chambers. Selected ones of the chambers include associated processing elements, for example, including heating and cooling elements, magnetic elements, membranes and lateral flow devices. The mixing device is also pivotable, for example, to facilitate the application of gravity force in the transfer of materials between the chambers and one or more compartments. The mixing device may operate manually by hand-held unit. Also, this mixing device may operate automatically with at least one driving unit.

Devices, systems and methods including a sonicator for sample preparation are provided. A sonicator may be used to mix, resuspend, aerosolize, disperse, disintegrate, or de-gas a solution. A sonicator may be used to disrupt a cell, such as a pathogen cell in a sample. Sample preparation may include exposing pathogen-identifying material by sonication to detect, identify, or measure pathogens. A sonicator may transfer ultrasonic energy to the sample solution by contacting its tip to an exterior wall of a vessel containing the sample. Multipurpose devices including a sonicator also include further components for additional actions and assays. Devices, and systems comprising such devices, may communicate with a laboratory or other devices in a system for sample assay and analysis. Methods utilizing such devices and systems are provided. The improved sample preparation devices, systems and methods are useful for analyzing samples, e.g. for diagnosing patients suffering from infection by pathogens.

Multi-component separation devices configured to separate components of a liquid sample by centrifugation are provided. Aspects of the separation devices include a container having a distal end and a proximal end and a buoy configured to be displaced along a longitudinal axis within the container where the buoy includes one or more sealed chambers. Also provided are methods of using the subject devices to separate components of a multi-component liquid sample such as whole blood, bone marrow aspirate or stromal vascular fraction as well as systems suitable for practicing the subject methods.

A liquid analyzing device includes a carrier, a driving unit, a rotating plate and a transmission mechanism. The driving unit is adapted to drive the carrier to rotate. The rotating plate is rotatably disposed on the carrier and adapted to support an analyzing cassette. The transmission mechanism is connected between the carrier and the rotating plate. When the driving unit drives the carrier to rotate to enable a rotation speed of the carrier to be changed and cross a predetermined rotation speed, the rotating plate rotates relatively to the carrier.

A liquid analyzing device includes a carrier, a rotating plate, and a driving unit. The rotating plate rotatably connected with a pivot portion of the carrier contains a test liquid. The rotating plate or the driving unit has a stopping portion. When the driving unit drives the rotating plate to rotate so the stopping portion moves to a first position and interferes with the carrier, the driving unit applies driving force to the pivot portion of the carrier along a first rotation direction through the rotating plate. When the carrier rotates along the first rotation direction and the driving unit applies driving force to the rotating plate along a second rotation direction opposite to the first rotation direction, the rotating plate rotates relative to the carrier, the stopping portion moves to a second position and interferes with the carrier, and the driving unit applies driving force to the pivot portion of the carrier along the second rotation direction through the rotating plate.

A microscope slide holder comprising a slide support member and at least one acoustic source for introducing acoustic waves to a microscope slide in communication with the slide support member such that one or more fluids present on the surface of the microscope slide are contactlessly mixed.
