The invention relates to a substrate for testing samples, in particular cells or molecules, wherein the substrate comprises a fluid system comprising a sample chamber configured in the substrate for storing and testing samples and at least one liquid reservoir in fluid communication with the sample chamber, and wherein the substrate comprises a passive blocking element capable of assuming a closed position and an open position, wherein in the closed position a fluid exchange between the sample chamber and the liquid reservoir is blocked.

Substrate for testing samples and system comprising the same

The present invention relates to a cover device for a sample carrier, comprising a sticky surface area for connection to the sample carrier, wherein the sticky surface area is configured such that the sample carrier is covered in liquid-tight fashion after connection of the cover device to the sample carrier in the sticky surface area.

Cover device for sample carrier

The invention relates to a sample chamber for testing samples, comprising a bottom plate and a cover plate connected thereto, a sample reservoir for receiving a liquid and/or a sample to be tested, and a contact electrode which is arranged entirely in the bottom plate, in the cover plate or between the bottom plate and the cover plate and which is electrically conductively connected to a conductor element or semiconductor element disposed in and/or on the sample chamber, wherein the bottom plate and/or the cover plate are designed in such a way that an electrical contact with the contact electrode can be established from the outside in such a way that an electrically conductive connection to the conductor element or to the semiconductor element can be established from the outside through the bottom plate or through the cover plate via the contact electrode.

Sample chamber

The invention relates to a method of positioning an organic, biological and/or medical specimen in a desired partial region of a specimen carrier, comprising the steps arrangement of a gel in a partial region of the specimen carrier, polymerization or gelification of the gel, by means of which a polymerized gel is obtained, whereby the polymerized gel at least partially, in particular horizontally, delimits the desired partial region and introduction of the specimen into the specimen carrier, in particular into the desired partial region of the specimen carrier.

Method of positioning an organic, biological and/or medical specimen

A microfluid device for producing diffusively built gradients comprising a bottom plate and a cover plate, wherein the cover plate has recesses and is connected to the bottom plate in a liquid-tight manner so that the recesses form at least two reservoirs and one observation chamber, which connects the reservoir, a reservoir can be filled particularly through an inlet/outlet through the cover plate, and the cross-sectional surface of the observation chamber is at least 5 times, preferably at least 200 times smaller at the aperture of the observation chamber into one of the reservoirs than the maximum cross-sectional surface of the reservoir in parallel to this cross-sectional surface of the observation chamber.

Microfluid device and method of producing diffusively built gradients

The invention comprises a sample chamber for microscopic examinations, comprising a reservoir for receiving a sample, the reservoir being defined by a bottom plate and a side wall, and a parting plate disposed in the reservoir and being parallel to the bottom plate, the parting plate in the reservoir being disposed at a height which is lower than the minimum height of the side wall, so that it divides the reservoir into an upper and a lower partial reservoirs, the lower partial reservoir and the upper partial reservoir being laterally completely bordered by the side wall, and the upper and the lower partial reservoirs being connected by at least one inlet/outlet.

Sample chamber with parting plate

A laboratory dish comprises an incubation container, containing cultured cells, for observation through a microscope, in which a partitioning member partitions an interior of the incubation container into a plurality of incubation chambers by substantially perpendicular walls. The partitioning member tightly fits to a bottom portion of the incubation container, thereby capable of retaining in separation a liquid inputted in each of the incubation chambers from liquids in the other incubation chambers. A cover member covers an upper portion of each of the incubation chambers partitioned by the partitioning member and tightly fitted to the partitioning member. A whole or part of the cover member is formed of a transparent member, and the upper portion of each incubation chamber is formed with an opening via which to input the liquid.

Incubation container

The invention relates to a sample chamber with a cover plate and a bottom plate which is joined thereto in a fixed manner, wherein a recess is provided in the cover plate so that a reservoir is formed by the bottom plate, wherein a planar element with holes is provided in the reservoir, wherein the holes have a predetermined arrangement and/or size.

Sample chamber and method for the production thereof

The invention relates to a specimen carrier for the study of cell growth, comprising a substrate with a reservoir with a bottom, wherein the reservoir is filled up to a predetermined height of the side wall, which is smaller than the complete height of the reservoir, with a carrier material for cell growth and the side wall of the reservoir is formed such that a predetermined contact angle of the carrier material can be adjusted with respect to the side wall.

Specimen carrier for the study of cell growth

The present invention relates to a valve unit for a microfluid system comprising a first and a second fluid reservoir, a flow chamber, a fluid channel array and a conveying means, said first fluid reservoir being, via the flow chamber, in fluidic communication with the second fluid reservoir through the fluid channel array, wherein the valve unit can be brought from a first state to a second state so that, in said first state, a fluid can be conveyed by the conveying means from said first fluid reservoir through the flow chamber in a predetermined direction of flow into the second fluid reservoir, and so that, in said second state, a fluid can be conveyed by the conveying means from said second fluid reservoir through the flow chamber in a predetermined direction of flow into the first fluid reservoir.

Valve unit for a microfluid system

The present invention relates to a sample chamber for a liquid, wherein at least one part in the interior of the sample chamber comprises a fluid-absorbent and/or fluid-permeable plastic, which is essentially degasified in at least one area and/or in which a predetermined fluid and/or predetermined solid is stored in soluble form in at least one area.

Sample chamber for a liquid

The invention relates to a device for microfluid analyses for a substrate with plane base surface and cover surface, wherein a chamber is integrated in the substrate for receiving liquid with at least two admissions and a semipermeable or permeable membrane is arranged in the chamber, wherein the chamber is subdivided by the membrane into two sectional chambers with at least one admission each.
