摘要:
Sample preparation device for receiving in sealing relation one or more filter assemblies and one or more sample containers, each container uniquely positioned within the device to receive filtered sample from a designated filter. The device includes a body, a lid disposed on the body, a container tray, a base, an integrated seal on the body, a valve and a valve actuator. The tray can be disposed in a vacuum chamber defined by the lid and the body, and one or more sample containers can be disposed in the tray. When properly positioned in the tray in the vacuum chamber, each container is in fluid communication with a single respective filter assembly disposed in sealing relation in a respective aperture in the lid. A single actuation of a valve to place the vacuum chamber under vacuum causes the lid to seal to the base and drives the simultaneous filtration of a plurality of samples.

A container and a container engaging member. The container engaging member may include a sample holder or reservoir, a filtration element and collar. In the assembled condition, the sample holder or reservoir is upstream of the filtration element, the container is downstream of the filtration element, and the sample holder or reservoir is attached to the container. The container engagement member is engageable and disengageable from the bottle or container in a quick attach, quick release manner, such as with only a 90 degree, ¼ turn. A tactile and/or audible indication that the engagement is complete is provided.

The embodiments disclosed herein are directed to an apparatus useful in conducting detection of compounds on blotting membranes. The device is comprised of several layers including a porous support layer below the blotting membrane(s), a flow distributor above the blotting membrane(s) and optionally a well on the flow distributor to contain the liquid to the desired area and to allow for lower starting volumes of such liquid. Preferably, the flow distributor is a non-binding or low binding hydrophilic porous membrane such as a 0.22 micron membrane and the support layer is a grid or sintered porous material. The distributor and support are held together to form an envelope around the membrane(s). The use of a hinge, clips and other such devices is preferred in doing so.

Apparatus and method for Immunohistochemistry, including a slide holder assembly fixture, a slide holder, a slide holder frame, and a slide holder frame assembly adapted to be placed in communication with a driving force to draw fluid through the slide holder. The slide holder may include an injection port that allows consistent fluid delivery and recovery, while minimizing the introduction of air bubbles. The slide holder may include a reservoir that allows for filling, soaking, rinsing, flushing, uniform antibody coverage of the tissue and reduces handling time, space, and errors, and one or more sample chambers. The slide orientation in the slide holder allows for visualization of label information and tissue to confirm adequate antibody coverage. A multi-port frame allows multiple assays to be carried out concurrently, and is removable from a vacuum manifold and allows for easy transport from the vacuum manifold to an incubator/refrigerator and back.
