Quartz Glass Bell Jar

Upgrade your semiconductor processing with our high-purity fused silica quartz bell jars. Specifically designed for CVD (Chemical Vapor Deposition) and plasma reaction environments, these chambers offer exceptional thermal stability and chemical resistance. Each unit features a precision-welded gas inlet side arm and an integrated internal distributor to ensure uniform gas flow across the wafer surface. Whether you are scaling up production or conducting R&D, our CNC-machined quartz solutions provide the vacuum integrity and purity your process demands.
