Miniature pumps for NASA Glenn research projects

As part of the OASIS (Observation and Analysis of Smectic Islands in Space) project, tested in 2015 on the International Space Station (ISS), the formation of single-layer liquid crystals and the analysis of defect formation mechanisms were carried out in microgravity, which is difficult to reproduce on Earth. The goal is to develop liquid crystal displays (LCD) that work better in space. The experimental analyzer was equipped with our ultra-compact pumps (miniature syringe pump and miniature peristaltic pump).

Challenges and solutions

In order to reduce the cost of rocket transport to the International Space Station (ISS) and because the test space inside the station was limited, pumps were sought that were as small and light as possible. During development, the specifications of the syringe pump were reviewed several times and changed according to the results. The test equipment itself was successfully launched and tested in 2015 after various long-term checks, including ground tests and zero-gravity tests with aircraft.

Test equipment for space experiments must be extremely compact and lightweight to minimize launch costs, without compromising on quality and accuracy. NASA was very pleased with the flexibility and adaptability in terms of the results of multiple tests, as well as the quality of our high-quality products.
