The fact that this fusion instrument allows the easy loading of crucibles, molds and beakers, that it has over ten preset fusion programs and that is ready to use right of the box without any training makes it really easy to use. LeNeo fusion instrument is also known to enhance security for the operator since its safety door automatically locks to protect him against heat. The fully automated pouring avoids the manipulation of hot vessels.
Claisse LeNeo fusion instrument helps obtaining superior analytical performances as well as accurate and precise results. Its programmable fusion parameters ensure high fusion success rate.
