fluidicsenhet

Fluidicsenhet refers to a modular unit within a fluidic system that is designed to control the flow and handling of liquids and gases. It typically integrates microchannels, valves, pumps, sensors, and a control interface into a single enclosure or cartridge. The unit can operate on its own or as part of a network of similar modules to form a complete processing line.

Function and design: The fluidicsenhet directs fluid movement using integrated actuators such as pneumatic or electromagnetic valves and miniature pumps. It may include sensors for flow rate, pressure, temperature, and readouts from optical or electrochemical detectors. Control is provided by embedded controllers, field-programmable gate arrays (FPGA), or external software, enabling programmable sequencing, timed mixing, and feedback control.

Materials and fabrication: Fluidicsenheter are made from polymers such as PDMS or thermoplastics, as well as glass or silicon, chosen for chemical compatibility and biocompatibility. Microfabrication methods such as soft lithography, injection molding, or laser micromachining are common. Seals, gaskets, and standardized fittings ensure leak-free operation and reliable connections to tubing and other modules.

Applications: They are widely used in microfluidics, lab-on-a-chip systems, clinical diagnostics, chemical synthesis, environmental monitoring, and food safety. They enable automated sample preparation, reagent mixing, reactions, and analysis in compact, disposable or reusable formats.

Industry context: The concept emphasizes modularity, interoperability, and scalability. Fluidicsenheter are often designed to be stackable or plug-and-play within larger instruments, with standardized electrical and fluid interfaces. Ongoing development focuses on reducing dead volume, increasing throughput, and enabling portable, point-of-care platforms.
