Product Name: High Purity Gradient Conical Quartz Reducer Tube with Grooved Inner Wall
Dimension: Large End Outer Diameter Φ30mm * Small End Outer Diameter Φ25mm * Total Length 100mm
Structural Feature: Precision flow guide grooves processed on inner wall, integrally thermoformed
This conical tube is integrally thermoformed from high-purity quartz with customized flow guide grooves inside and smooth step-free tapered surface. It features high temperature resistance, resistance to hydrofluoric acid and concentrated acid/alkali, zero metal ion precipitation, high light transmittance, enhanced gas-liquid mass transfer and anti-blocking performance. The inner grooves strengthen medium turbulence and mass transfer efficiency, serving as adapter for different-diameter pipelines, bubbling washer and gas phase concentrator. Widely used in laboratory chemistry, semiconductor PV, lithium battery new materials, waste gas detection and tube furnace.
Core Advantages (vs Ordinary Smooth Quartz Conical Tubes and Metal Reducer Joints)Outstanding Corrosion Resistance: Withstand long-term flushing of hydrofluoric acid, concentrated strong acid and alkali at high temperature. Ordinary borosilicate glass cannot resist HF while metal joints tend to rust and release metal impurities contaminating high-purity materials.
Wide High-Temperature Service Range: Stable continuous operation at 200–1100℃, ultra-low thermal expansion coefficient and superior thermal shock resistance without cracking, chipping or deformation under cold-hot alternation.
Ultra-Low Impurity Precipitation: Integrally formed from 99.99% high-purity quartz without heavy metal dissolution, free of contamination to wafers, electronic carrier gas, high-purity electrolyte and micro lab reagents.
Enhanced Mass Transfer with Inner Grooves: Exclusive flow guide groove structure actively agitates gas and liquid media, produces finer bubbles and larger contact area, with better washing, absorption and deoxygenation effect than smooth-wall conical tubes.
Anti-Crystallization and Anti-Blocking: Grooves cut continuous adhesion surface of salt crystals to mitigate pipeline clogging, lower maintenance frequency for continuous production.
Full-Band High Transparency for Visual Inspection: High UV and visible light transmittance, allowing direct observation of internal bubbling, condensation and crystallization reactions for optical online monitoring experiments.
Precise Dimension and Excellent Sealing Performance: Strict tolerance of large and small end outer diameters for perfect matching with standard quartz tubes, good air tightness after assembly for vacuum and closed reaction systems.
