Preparations that make a difference - MO Precursors

To produce pure, perfectly reliable, and exact LEDs, the fundamentals have to be right. Our high-purity metalorganic precursors and dopants offer batch-to-batch uniformity, for producing high-quality LEDs.

You can choose between solid and liquid materials to find the best solution for your needs. We offer a wide choice of bubblers to ensure material transfer is secure, quick and 100% reliable.?

We’ve also spent decades perfecting our logistical and transportation systems to ensure?every?delivery of pure materials?is kept?safe?and sound, even before you start?making preparations?for the epitaxy chamber.?Regional I&A support is part of the package you buy from us.
