Measurement & Laboratory Technology
A laboratory device that became quieter and easier to assemble
A complete relaunch of the Disc Remover in-vitro diagnostics device: EMC-optimised housing design, new electronics, new embedded software on our framework semf.
The task
For nearly forty years Labsystems Diagnostics has been developing technologies for newborn screening and point-of-care testing. The company's neonatal products are in use in more than seventy countries.
The Disc Remover in-vitro diagnostics device was to be redeveloped from the ground up. Three things decided it: assembling the previous device was complicated and slow, field service management cost time and money, and the noise level spoilt the impression of quality.
The solution
The device was developed entirely anew: housing, electronics hardware and embedded software. The electronics design is EMC-optimised for use in a plastic housing. We prepared the documentation for international in-vitro diagnostics regulatory approval.
The result is designed for a long service life, low service and maintenance effort, optimised measurement tolerances and user-friendly operation. The housing was designed in cooperation with MKI · Matzku & Konz.
Technical highlights
The embedded software is built on semf, our own C++ framework. That speeds up development and keeps errors down.
The stepper motor control works to an accuracy of better than 0.1 millimetres. The axes detect their position through light barriers with daylight compensation, and optical sensors detect when a sample is loaded. Control and diagnostics run remotely over USB-VCP. We also wrote test software, which we used to run the performance tests.
