Ultra-Precision High-Purity Quartz Capillary Tube Custom Solution
Case Overview
This case targets customized mass production of ultra-fine quartz capillary tubes for a professional overseas laboratory analytical instrument manufacturer. The client’s core equipment involves micro-fluid delivery, high-precision gas sampling and constant-temperature capillary reaction testing, which puts forward extremely strict requirements on tube inner diameter consistency, surface smoothness, high-temperature stability and chemical purity. We delivered a full-set customized solution including ultra-fine aperture customization, uniform wall thickness control, high-purity treatment and stress-free finishing, completely solving the client’s problems of unstable fluid flow, easy tube blockage, corrosion damage and low test data repeatability caused by traditional capillary accessories.
Client Pain Points Before Cooperation
Traditional glass capillary tubes had large inner diameter tolerance and uneven tube walls, resulting in unstable micro-fluid velocity and inaccurate quantitative analysis data in precision testing.
Common low-purity capillaries were prone to chemical corrosion when contacting acidic reagents, organic solvents and high-temperature gas media, leading to inner wall peeling and short service life.
Ordinary capillary products had residual internal stress, and were easy to deform and block the pipeline under long-term constant-temperature working conditions, causing frequent equipment shutdown and maintenance.
Generic capillary tubes could not meet the client’s ultra-clean testing standards, and trace impurity precipitation would interfere with micro-component detection, reducing experimental accuracy and product qualification rate.
Our Customized Quartz Capillary Tube Solution
High-Purity Material Screening: Adopt 99.99% ultra-high-purity synthetic fused silica raw material with ultra-low metal ion and hydroxyl content. The material features excellent chemical inertness, avoiding impurity precipitation and ensuring zero interference for micro-analysis and high-precision testing.
Ultra-Fine Precision Sizing Control: Adopt professional one-time drawing molding process for quartz capillaries. Strictly control ultra-small inner diameter, outer diameter and wall thickness with high precision, realizing micron-level dimensional tolerance control. The inner tube hole is uniform and smooth to ensure stable and consistent fluid and gas transmission.
Stress-Free High-Temperature Treatment: All capillary tubes undergo secondary high-temperature stress relief annealing treatment to completely eliminate internal processing stress. The finished products feature strong thermal stability, not easy to deform or block during long-term constant-temperature operation and slight temperature fluctuation.
High-Grade Surface Finishing: Adopt high-temperature flame smoothing and ultra-fine cleaning process. The inner and outer walls of the capillary tube are free from burrs, micro-pits, bubbles and particle residues, with excellent light transmittance and ultra-clean surface performance, meeting laboratory high-purity testing standards.
Diversified Customized Specifications: Support customized production of various ultra-fine apertures, different length specifications and special cutting flat ends. Products are applicable to micro-fluid delivery, gas chromatography detection, capillary reaction and other multi-scene equipment matching requirements.
Delivery & Actual Operation Effect
We completed technical confirmation, sample testing verification and batch mass production efficiently. All products passed strict full-size dimensional inspection, high-temperature durability test, chemical corrosion resistance test and ultra-clean cleanliness detection before delivery, with all indicators meeting the client’s industrial precision standards.
After long-term continuous operation and equipment debugging by the client, the customized high-purity quartz capillary tubes achieved excellent practical application results: stable micro-fluid transmission with zero flow fluctuation, effectively improving the accuracy and repeatability of experimental detection data; no corrosion, deformation or pipeline blockage after long-term contact with chemical reagents and high-temperature gas; ultra-clean material performance realized zero impurity interference, greatly improving the qualified rate of precision testing; durable structural performance extended the service life of equipment accessories and reduced the frequency of equipment maintenance and replacement costs significantly.
