Laboratory and Chemical Applications
Our quartz tube blocks are precision-engineered from high-purity fused silica, designed for critical high-temperature applications in tube furnaces and process systems. With exact dimensions (e.g., O.D. 42mm, Height 15mm) and precisely drilled holes (e.g., 8mm, 10mm, 7mm), these blocks provide secure sealing, efficient gas distribution, and robust support for multiple process tubes. Ideal as a replacement part for furnaces like the GSL-1500X-RTP50 (Model QTB42) or for custom-built systems, our quartz blocks offer superior thermal stability, chemical inertness, and contamination control for demanding research and industrial processes.

Exceptional High-Temperature Stability
Crafted from high-purity fused silica, these tube blocks are designed to endure the extreme temperatures found in advanced tube furnaces (e.g., compatible with GSL-1500X-RTP50 and similar systems), ensuring long-term structural integrity and reliable performance.
Precision Sealing & Gas Management
Each block is precisely machined with accurate hole dimensions and spacing, allowing for secure and leak-tight insertion of multiple process tubes. This is critical for maintaining controlled atmospheres, managing gas flow, or achieving high vacuum within the furnace chamber.
High Purity & Contamination Control
The inherent high purity of quartz minimizes the risk of contamination to sensitive samples or processes, making these blocks ideal for applications in semiconductor manufacturing, advanced materials research, and other fields where purity is paramount.
Customizable Design for Diverse Applications
Beyond standard models (like QTB42), these quartz tube blocks offer extensive customization options. This includes varying outer and inner diameters, height, the number, size, and precise placement of holes, enabling them to perfectly integrate into a wide array of specialized furnace setups and unique experimental requirements.
Application Scenario
Multi-Tube Furnace Integration & Sealing
Essential for high-temperature tube furnaces that operate with multiple process tubes simultaneously. These quartz blocks provide precise alignment, support, and a critical sealing interface for individual reaction tubes, ensuring controlled atmospheres or vacuum within each channel.
Gas Distribution & Flow Control in Reactors
Used as a sophisticated manifold or feedthrough block to accurately deliver different gases to multiple reaction zones or samples within a high-temperature reactor. The precisely drilled holes facilitate individual gas lines, enabling complex multi-step syntheses or parallel experiments.
High-Purity Material Processing & Semiconductor Fabrication
Critical in applications requiring ultra-high purity environments, such as semiconductor diffusion, annealing, or epitaxial growth. The quartz material prevents contamination, and the block’s design ensures a stable, clean platform for processing wafers or delicate materials in inert or reactive gas flows.
Custom Laboratory & Industrial Furnace Systems
Highly adaptable for bespoke furnace designs and specialized thermal processing setups. Due to their customizable dimensions and hole configurations, these quartz blocks are perfect for unique research projects or niche industrial applications where standard furnace accessories are insufficient.
Handle with care
Quartz glass products are made from valuable materials and must be handled gently to avoid collisions and falls.
Regular maintenance
The maintenance of quartz tubes must be performed regularly to ensure their long-term stable performance. Regularly check the connections, fixings, and mechanical vibrations of the quartz tubes to prevent abnormalities. The exterior of the quartz tubes is prone to contamination from dust and moisture, so they should be cleaned regularly.
Storage environmen
When storing quartz tubes, care should be taken to avoid exposure to mechanical vibrations, shocks, and excessively high temperatures. They should be kept in a dry, cool, and well-ventilated place, avoiding direct sunlight and high-temperature environments.
While the Model QTB42 is specifically designed for the GSL-1500X-RTP50 furnace, we offer comprehensive customization services. We can manufacture quartz tube blocks with various outer diameters, heights, and custom hole configurations (number, size, and spacing of holes) to perfectly fit and function with virtually any other high-temperature tube furnace or custom process system you may have.
Made from high-purity fused silica, these quartz tube blocks can withstand very high continuous operating temperatures, typically up to 1100°C, with flash temperatures potentially higher depending on the specific grade and design. Their extremely low coefficient of thermal expansion provides excellent resistance to thermal shock, minimizing the risk of cracking even during rapid heating and cooling cycles within the furnace.
The precise machining of the holes allows for a tight, reliable seal when process tubes or gas lines are inserted, effectively isolating each channel or maintaining a single controlled atmosphere throughout the furnace. This design is crucial for preventing gas leakage, ensuring specific gas environments (inert, reactive), or achieving and maintaining high vacuum levels for sensitive high-temperature material processing applications.
