Accubath™ Heated Quartz Process Tank

Accubath Heated Quartz Process Tank Silicon Nitride Etch


Imtec has set the global standard for both static and recirculating heated quartz baths. Our complete line of Accubath systems deliver unsurpassed process performance, reliability, and safety in wet systems throughout the world. Our commitment to engineering excellence has consistently given Imtec’s customers exceptionally dependable and advanced process equipment. The Accubath combines the highest quality materials and engineering designs to create a quartz bath that enhances your process.

Our quartz tanks are suitable for use in processes using quartz-compatible chemistries up to 190°C. Quartz is known for its durability and non-reactivity to a variety of chemistries. We employ experienced quartz welders and machinists to create high purity, uniform tanks in a variety of standard and custom sizes, with the ability to add high-strength welded quartz inlets and probe holders.

For the most rigorous processes, we offer our patented AquaSeal technology, which protects against the leading cause of vessel failure. It incorporates a dual sealing feature by directing DI water to flow over the RTV seal area, cooling it while forming a barrier against chemical fumes. Please see our material compatibility chart to find out which material works best for your process.
