Fused Quartz Bubbler Tubes & Gas Spargers

Fused Quartz Bubbler Tubes & Gas Spargers

Fused quartz bubbler tubes and gas spargers designed for high-purity semiconductor, chemical, and laboratory processes. Made from ultra-high-purity fused silica and assembled by precision flame-fusion, these components deliver excellent chemical inertness, thermal stability, and clean, precise dispersion of gases into liquids or slurries in critical environments.

What to Provide for a Quote

• Drawing (PDF/STEP) or key dimensions: tube OD/ID/length; immersion depth; bend/arm geometry
• Sparger head style: multi-orifice tip, perforated bulb, slotted tip, or porous head (by request)
• Target bubble size / distribution, gas type & flow-rate range; liquid/chemistry and operating temperature
• Connection type: straight tube, ground joint, ball/socket, hose barb, or KF/ISO/CF adapter
• Cleanliness level and surface finish of wetted areas; backflow/anti-siphon requirements
• Any test requirements (helium leak, flow characterization, hold/pressure test) and packaging level

Key Specifications

• Material: High-purity fused quartz (SiO₂); material certificate available on request
• Configurations: Straight or L-shaped dip tubes; single or multiple bulbs; side ports; integral hangers/positioning collars
• Dispersion Options: Laser-drilled or etched orifices; slotted tips; optional porous diffuser heads
• Construction: Smooth flame-fused transitions and stress-relief annealing; chip-free, polished ends
• Connections: Ground taper joints, ball/socket joints, hose barbs, or vacuum flanges as specified
• Cleanliness: Ultrasonic/DI cleaning; Class-100 compatible packaging
• Service Note: Intended for vacuum or low positive pressure; any pressure rating is design- and test-dependent

Material Properties (Typical)

• Excellent chemical resistance and low extractables (note: HF attacks quartz)
• Very low thermal expansion and good thermal-shock tolerance
• Electrically insulating, low outgassing; optically clean wetted surfaces

Processing & Design Notes

• Match orifice count/size to the target bubble size and gas flow; distribute ports to avoid coalescence
• Provide vent paths for blind cavities to prevent virtual leaks in vacuum systems
• Use generous fillets at junctions to minimize stress and particle traps; polish wetted surfaces where needed
• Define immersion depth and anti-siphon features for safe shutdown; add drain/flush provisions if required
• We can advise practical tolerances for straightness, concentricity, and orifice placement based on geometry

Inspection & Testing

• Dimensional verification: OD/ID/length, bend geometry, orifice size/count/placement
• Optional: helium leak test (vacuum duty), flow-rate and pressure-drop characterization, cleanliness report
• 100% visual inspection for chips, micro-cracks, inclusions, and contamination

Applications

Gas dispersion in wet benches and chemical baths, precursor/vapor bubbling, mixing and aeration in high-purity systems, scrubbing and analytical/lab processes

Packaging & Storage

Protective caps on orifices and ends; anti-static, vacuum-sealed packaging with shock-absorbent foam and rigid outer protection. Store dry (<40% RH) at 10–30 °C, away from HF-containing chemicals.
