China Wholesale Quartz Condenser Tube Manufacturers & Supplier Serving Jakarta

Quartz condenser tubes and fused silica laboratory apparatus are classified under HS Code 7017.10.00 (Laboratory, hygienic or pharmaceutical glassware, whether or not graduated or calibrated, of fused quartz or other fused silica). Nivra Quartz provides comprehensive export documentation including Commercial Invoice, Packing List, Certificate of Analysis (CoA), and Form E (ASEAN-China Free Trade Certificate of Origin), which allows qualified Indonesian importers holding an active NIB (Nomor Induk Berusaha) to claim preferential import duty concessions (0% tariff rates) under ACFTA regulations.

Our condenser spiral tubes undergo a multi-stage thermal annealing process at 1150°C to release all residual mechanical and flame-working stresses, validated under polariscopic cross-polarization inspection. With a negligible coefficient of expansion (5.5 × 10⁻⁷ /°C), our fused quartz tubes operate seamlessly with cooling water pumped directly from local ambient sources (28°C to 34°C) while condensing reflux vapors exceeding 800°C without risk of catastrophic thermal fractures.

Yes. A primary share of our production consists of custom OEM/ODM quartz equipment. If your facility possesses an imported European, Japanese, or legacy reactor system with obsolete or cracked condenser glassware, you can send us a dimensional sketch, DWG/DXF/STEP file, or high-resolution photos with dimensional callouts. Our engineering team confirms tolerances (typically ±0.2mm on standard diameters, ±0.05mm on precision ground ground-joints like NS 29/32 or NS 45/40) before producing pre-production samples.

Standard condenser tubes and custom prototype batches have a manufacturing lead time of 7 to 14 working days depending on dimensional complexity. For regular sea freight, shipments depart from Shanghai Port or Qingdao Port directly to Tanjung Priok (Jakarta) with an average maritime transit duration of 12 to 16 calendar days. Urgent prototyping orders can be air-freighted via DHL, FedEx, or air cargo directly to Soekarno-Hatta International Airport (CGK) within 3 to 5 business days.

Exporting fragile high-aspect-ratio glassware overseas requires meticulous packaging engineering. Every quartz condenser tube is first wrapped with dust-free static shielding, nestled inside customized high-density extruded expandable polyethylene (EPE) shock-absorbing foam molds, encased in rigid multi-wall inner cartons, and secured within custom heavy-duty plywood export crates. Crates feature integrated external shock/tilt indicators. In the unlikely event of transit damage covered under our CIF terms, we provide immediate free replacement production upon digital photographic confirmation.

To support both corporate pilot plant evaluations and large industrial replacements, we provide flexible low MOQ requirements. Standard diameter quartz condenser tubes and spiral assemblies start from 1 to 5 pieces. Precision micro-capillary tubes or standardized optical sight plates have an MOQ of 10 to 50 pieces. We welcome pilot testing orders to allow engineering teams to verify purity, dimensional accuracy, and thermal stability in-situ prior to executing blanket annual purchase orders.
