Capillary Quartz Tube Factory & Exporters Serving Bordeaux

For precision-drawn micro-capillaries used in HPLC flow cells, gas chromatography, or fiber optic collimators, our CNC-controlled thermal pulling towers hold inner diameter (ID) tolerances to ±0.005 mm (±5 μm) for bores between 0.1 mm and 1.5 mm. For standard analytical tubing (ID 2.0 mm to 10.0 mm), standard production tolerances are held to ±0.02 mm to ±0.05 mm. Every batch destined for critical optical or analytical facilities in France is validated using optical microscopy and air-decay pressure decay tests, with full dimensional inspection reports provided prior to dispatch.

Capillary tubes and ultra-thin quartz products are exceptionally vulnerable to transit bending stress and harmonic vibration. We isolate each individual capillary tube within dedicated high-density grooved EPE (Expanded Polyethylene) foam beds, sealed inside shatterproof acrylic rigid tubing, and packed into multi-wall export cartons. For bulk consignments or large diameters, these cartons are suspended inside custom, ISPM-15 fumigation-certified marine plywood crates equipped with shock-watch indicator labels. We provide a 100% transit breakage guarantee: in the rare event of transit damage documented upon arrival, immediate replacement units are fabricated and dispatched via priority air express at our expense.

For enological laboratories conducting UV spectrophotometric assays (such as measuring total polyphenol index at 280 nm, anthocyanin color ratios, or enzymatic NADH/NADPH tracking at 340 nm), JGS1 (Synthetic Fused Silica) is recommended. JGS1 guarantees over 90% transmission down to 185 nm and has virtually zero fluorescence interference. If your application is limited to visible/near-IR spectrum measurement or general chemical digestion (e.g., Kjeldahl nitrogen determination in must), cost-effective JGS2 is ideal. If your focus is Fourier-Transform Infrared (FTIR) spectroscopy of volatile aromas, JGS3 is required due to its low hydroxyl (OH⁻ ≤ 5 ppm) content that eliminates the water absorption band at 2730 nm.

Fused quartz glass products entering France from China typically fall under EU TARIC / Combined Nomenclature code 7002.31.00 (Tubes of fused quartz or other fused silica) or 7017.10.00 (Laboratory glassware of fused quartz). We routinely trade under DAP Bordeaux, CPT Mérignac Airport, or CIF Port of Bassens, and can provide full DDP (Delivered Duty Paid) arrangements through our forwarder partners. Standard air courier shipments (via DHL/FedEx/UPS Express) arrive at your facility in Bordeaux within 4 to 7 business days following dispatch. Custom prototyping takes 7–10 days; mass production runs take 2–3 weeks depending on geometry.

Yes. OEM/ODM custom fabrication is our core specialty. Our processing facility accepts blueprints in PDF, CAD (DWG/DXF), and 3D STEP/IGES formats. We execute micro-drilling (holes down to 0.3 mm), precision surface grinding, fire polishing of capillary apertures, quartz-to-quartz optical contact welding, and specialized glass-to-metal graded seal transitions. Our engineering department reviews manufacturability and returns formal technical feedback along with a quotation within 5 business hours.

We maintain an engineer-friendly procurement model. For standard capillary tubing and catalog tubes, the MOQ starts at just 1 to 10 pieces, enabling university researchers, startup engineering teams, and winery R&D departments to evaluate prototypes without excessive capital expenditure. For complex CNC-machined wafer carriers, quartz boats, or specialized cuvettes, sample batches of 1–5 units are readily supported before committing to series volume production.
