Replacement Quartz Tube
High-Purity Reaction Chamber for DEAR-MPCVD Diamond Growth
The DEAR-MPCVD Replacement Quartz Tube serves as the primary reaction chamber for the Blue Wave Semiconductor DEAR-MPCVD system. Manufactured from high-purity quartz with rounded, fired edges that protect O-rings during installation and minimize seal wear over repeated changeouts.
Easy tube swapping dramatically reduces cross-contamination between different dopant chemistries, enabling faster process changeovers and cleaner experimental transitions without lengthy in-situ cleaning.
Contact us for pricing. Replacement tubes available individually or in multi-tube sets for labs with frequent process changeovers.
Wholesale & Multi-Tube Sets
Labs running multiple process chemistries benefit from keeping spare tubes on hand. Contact us for multi-tube pricing and institutional discounts.

The Core of Your DEAR-MPCVD Reaction Environment
Diamond CVD Growth
Serves as the primary reaction chamber for MPCVD diamond growth, providing a stable, clean plasma environment with excellent optical transparency for uniform microwave energy distribution.
Rapid Process Changeovers
Easy tube swapping reduces chamber prep time when switching between different dopant chemistries, substrate types, or experimental recipes — no lengthy in-situ cleaning required.
High-Purity Processing
Replacing the tube between runs eliminates impurity carryover from previous experiments, ensuring each growth run starts in a clean, pristine chamber environment.
Plasma Monitoring
The optical clarity of quartz allows visual and optical monitoring of plasma behavior and substrate conditions during the deposition process without opening the chamber.
