Frequently Asked Questions by Odesa & Regional Buyers
Key technical, logistical, and commercial inquiries answered directly by our chief quartz application engineers.
What are the exact dimensional tolerances for quartz capillary tubes supplied to Odesa? +
For standard precision fused silica capillary tubes, our outside diameter (OD) and inside diameter (ID) tolerances are held to ±0.01 mm. For ultra-precision chromatography, laser fiber ferrule, or electrophoresis capillary applications, we produce micro-bores with tolerances down to ±0.003 mm and concentricity within 0.002 mm. Each custom shipment includes a factory Certificate of Conformance (CoC) and micrometer inspection report.
How does your factory protect fragile quartz tubes and lamps from freight breakage to Ukraine? +
Fragile quartz glassware and IR lamps require multi-tier isolation packaging. Individual tubes are packed inside sealed polyethylene dust-free sleeves, nested within high-density shock-absorbing EPE (expanded polyethylene) foam channels, and cased in heavy-gauge 5-ply fluted export cartons. For air and multimodal shipments to Odesa via Constanța or Poland, cartons are secured inside fumigated wooden crates with tilt/impact indicator labels. Our historical transport damage rate is strictly below 0.15%.
Can you produce custom infrared emitters based on old, unbranded lamps taken from our plant machinery? +
Yes. Many industrial processing plants in Odesa operate legacy European, Turkish, or Asian equipment where original lamp part numbers are worn off or obsolete. If you can provide the total length, heated filament length, voltage (e.g., 120V, 220V, 380V), wattage, tube profile (single tube 10–12 mm or twin tube 11x23 mm / 15x33 mm), ceramic end-cap type, and high-resolution photos, our engineering office will draft a manufacturing CAD drawing within 24 hours for your confirmation.
Which HS Codes and documentation do you provide for customs clearance into Ukraine? +
For clear fused quartz capillary tubing and solid rods, we export under HS Code 7002.31.00.00 (Tubes of fused quartz or other fused silica) or 7002.20.90.00. For halogen and carbon fiber infrared lamps, shipments fall under HS Code 8539.49.00.00 (Ultraviolet or infrared lamps). We supply certified Commercial Invoices, Packing Lists, Certificates of Origin (CO), and test data sheets required by Ukrainian customs brokers for smooth import tariff processing.
How does a short-wave halogen lamp compare with a medium-wave carbon fiber lamp in energy efficiency? +
Efficiency is governed by how effectively the target material absorbs specific wavelengths. Short-wave halogen emitters (peak at 1.0–1.2 µm) provide deep penetration and reach 100% output within 1 second, making them unbeatable for rapid PET preform reheating, metal coating curing, and dense composite heating. Medium-wave carbon fiber lamps (peak at 2.0–2.4 µm) match the natural absorption bands of water, wood, plastics, and solvent-based inks, drying surface layers up to 40% faster while eliminating surface skinning or blistering.
What is the minimum order quantity (MOQ) for custom quartz capillary configurations? +
For standard bore diameters and wall thicknesses that we regularly pull on our drawing lines, MOQ begins at just 8 to 10 pieces. For custom tooling runs requiring specialized die setups (e.g., unusual multi-lumen profiles or custom synthetic silica purity tiers), sample trial runs typically start at 25–50 pieces, transitioning to full production runs upon physical testing sign-off.
Can your quartz glass instruments resist exposure to strong acids used in maritime testing labs? +
Yes. Fused silica quartz exhibits exceptional chemical resistance against practically all acids—including hydrochloric, sulfuric, nitric, and aqua regia—at both room temperature and elevated operational levels. The only substances that actively attack quartz glass are hydrofluoric acid (HF) and concentrated phosphoric acid at temperatures above 150°C. This makes our capillary products and flow cells the gold standard for testing port water, bunker fuel, and industrial effluents in Odesa.
