Abstract:
A flow cell for a photometric device includes a module having a body with a distal face defining an annular channel. The body also defines an axial central passage and an axial flow channel. A second module has a body with a proximal face defining an annular channel. The second body also defines an axial flow channel in fluid communication with the first axial flow channel. A light guiding member is within the central passage for exposing a fluid in the flow channels of the modules. An assembly seals an interface between the distal and proximal faces such that the fluid does not leak from the flow channels. The assembly has a metal gasket between the distal and proximal faces, the metal gasket defining a flow path between the flow channels, a first sealing member in the first annular channel and a second sealing member in the second annular channel.

An immersion sensor for analysis of liquids or melts includes an immersion carrier, a detector and a radiation-guiding unit, and a sample chamber arranged in the immersion carrier. The sample chamber has an inlet opening for liquid or melt, and the sensing components for measurement of the liquid or melt act inside the sample chamber.
Abstract:
An apparatus for analysis of a sample and in particular of a biological sample. The apparatus contains a microfluidic chip with dies, adapted to be selectively activated or deactivated by presence of target molecules in the biological sample. The apparatus further contains a light source to emit light for illumination of the microfluidic chip and an optical filter to allow passage of the light from the dies once activated or deactivated by the presence of the target molecules. A method for pressurizing a microfluidic chip is also disclosed, where a chamber is provided, the chamber is connected with the microfluidic chip and pressure is applied to the chamber.
Abstract:
Described and claimed is an interchangeable tip-open cell fluorometer comprising a housing and a fluorometric probe tip interchangeably connected to the housing, the probe tip including a probe tip housing defining an open cell and enclosing a probe optical arrangement, the probe optical arrangement including an excitation source and a fluorescence detector wherein the excitation source is aimed directly into the fluorescence detector such that a sample can be fluorometrically detected.
