Quartz Combustion Boat Manufacturers & Factory Serving Albania

Devitrification is the phase transformation of metastable amorphous fused silica into crystalline cristobalite, which induces micro-cracking upon cooling below 270°C. This phenomenon is catalyzed primarily by surface alkali contamination (Na, K, Ca). Kemzo quartz boats maintain total metallic and alkali impurities below 15 ppm, with pristine flame-polished surfaces. In standard combustion analysis operating at 1,150°C to 1,250°C, our boats resist devitrification across dozens of repeated thermal cycles, provided samples are handled using clean platinum-tipped or nickel tongs without direct skin contact.

For import into the Republic of Albania through the General Directorate of Customs (Drejtoria e Përgjithshme e Doganave), we supply fully compliant commercial invoices bearing your corporate NIPT (Numri i Identifikimit të Personit të Tatueshëm), detailed packing lists, Certificates of Origin (CO), and factory material test reports. Quartz combustion boats and laboratory quartzware are typically cleared under Harmonized System (HS) Code 7017.10 (Laboratory, hygienic or pharmaceutical glassware, whether or not graduated or calibrated, of fused quartz or other fused silica). This classification facilitates straightforward processing under Albanian TARIC tariff tables.

Yes. We routinely manufacture exact-dimension fused quartz and fused silica combustion boats, inner protection tubes, and catalyst chambers directly compatible with standard automated analyzers from LECO®, Eltra®, Horiba®, and Elementar®. Provide us with the OEM reference part number or dimensional parameters (Length × Width × Height × Wall Thickness), and our engineering team will provide precision-matching vessels with identical or tighter tolerances at direct-manufacturer pricing.

To eliminate post-combustion slag without damaging the quartz substrate, soak the cooled boats in dilute hydrochloric acid (10-15% HCl) or hot concentrated nitric acid (HNO&sub3;) to dissolve metallic oxides. Rinse thoroughly with deionized or distilled water and dry in an oven at 120°C. Never use hydrofluoric acid (HF) or strong alkaline solutions (such as concentrated NaOH or KOH) as they rapidly dissolve the SiO&sub2; network. For severe carbonaceous residues, bake the empty boats in an oxidizing muffle furnace at 900°C for 30 minutes to burn off residual carbon.

Standard catalog boat dimensions are kept in stock with no strict minimum order quantity (small batch sample orders of 10 to 50 pieces are welcomed for analytical qualification). For custom dimensional prints or specialized handled designs, our typical MOQ is 50 to 100 units depending on geometry. Custom production lead times typically range from 7 to 14 working days, followed by rapid air dispatch or sea consolidation to Durrës.

With over a decade of international shipping experience, our damage incidence rate remains below 0.1%. Each quartz boat is individually nestled in high-density polyethylene micro-foam cutouts, wrapped in multi-layer bubble shielding, and packed into compartmentalized five-layer corrugated boxes. For sea and multimodal transit, these boxes are placed inside custom shock-isolated marine plywood crates with water-resistant inner linings. In the rare event of transit damage, Kemzo provides free replacement upon photo verification.
