Cartridge and apparatus for preparing a biological sample
First Claim
1. A cartridge for processing a sample carried on a substrate, the cartridge comprising:
- a cartridge body comprising;
a reaction chamber;
walls that surround the reaction chamber and define an opening extending between the walls and across the reaction chamber;
a fluidic inlet system configured to provide at least one reagent fluid to the reaction chamber;
a fluidic outlet system configured to receive fluid from the reaction chamber; and
corresponding pump membranes positioned in the fluidic inlet system and the fluidic outlet system, wherein the corresponding pump membranes are configured to induce a pressure-driven fluid flow from the fluidic inlet system through the reaction chamber to the fluidic outlet system;
wherein the fluidic inlet system, the reaction chamber, and the fluidic outlet system are configured to be closed to an exchange of liquids with an environment outside the cartridge by the walls of the cartridge body and a wall of the substrate carrying the sample in response to an attachment of the substrate carrying the sample over the walls of the cartridge body and the opening.

Abstract
A cartridge and an associated apparatus for preparing a biological sample includes a reaction chamber configured to be closed by a substrate carrying the biological sample, where the reaction chamber is connected to a fluidic inlet system and a fluidic outlet system. When the substrate closes the reaction chamber, the fluidic inlet system, the reaction chamber, and the fluidic outlet system constitute a fluidic system that is closed to an environment outside the cartridge with respect to an exchange of liquids. Further, a pressure-driven flow through the reaction chamber may be induced by actuation of deformable membranes formed in the cartridge.
