Clear capillary glass tubes from Xinxiang Xinbo Glass Quartz Products Co., Ltd. are precision-drawn tubes made from optical-grade quartz glass, designed for laboratory, chemical, and medical applications requiring high thermal stability and light transmission. The tubes are manufactured with consistent wall thickness and low bubble content, with dimensions customizable to customer requirements. Transmittance exceeds 91.8% across the visible spectrum, meeting standard optical glass performance thresholds.
The material is classified as JGS1 or JGS2 quartz glass, known for low thermal expansion and high purity. Surface quality is maintained at 40/20 or 60/40 scratch-dig standards per ISO 10110. Thickness ranges from 0.8mm to 30mm, with tolerances of +/-0.01mm to +/-0.2mm depending on specification. These tubes are not tempered but are produced for structural integrity under thermal stress, commonly used in heat radiation plates and chemical reactors.
Buyers include manufacturers of analytical instruments, semiconductor equipment, and industrial heating systems. Applications span from UV lamps and boiler sight glasses to chromatography components. Orders are accepted in quantities from 1,000 pieces per size. Packaging is in foam-lined cardboard boxes with individual tube separation. Shipping is handled from Shanghai, Qingdao, or Lianyungang ports under FOB or CIF terms.

Before ordering, confirm the exact quartz grade (JGS1, JGS2, or JGS3) and surface quality specification (scratch-dig rating). Request a material certificate and transmittance report for the batch. Verify that the thickness and outer diameter match your application’s fit requirements. Do not assume certifications like CE or CCC are valid unless the supplier provides valid documentation with test lab accreditation.
Confirm the Incoterms offered - FOB Shanghai or Qingdao is typical. Lead time is 20 to 35 days for custom sizes, longer for large batches. Payment terms are commonly T/T or L/C. Request a sample batch before full production to test for dimensional accuracy, surface flaws, and optical clarity under your intended lighting conditions.
Quality inspection should include dimensional checks with micrometers, visual inspection under 20x magnification for bubbles or inclusions, and transmittance verification with a calibrated spectrophotometer. Each shipment should include a packing list with batch numbers and a certificate of conformity. For critical applications, request third-party inspection reports from SGS or Bureau Veritas.
