Engineered to operate at continuous temperatures up to 1100°C and peak thermal exposures of 1450°C. Fully customized to CAD specifications, DIN/ISO standards, and metallurgical assay riggings.
In the demanding metallurgical and geological assay environments across Mongolia—from the vast porphyry copper-gold operations of Oyu Tolgoi in the South Gobi to the critical molybdenum-copper complexes of Erdenet and the burgeoning rare-earth exploratory basins in Western Mongolia—thermal and chemical reliability in laboratory glassware is a strict operational imperative. Routine borosilicate 3.3 laboratory glass frequently succumbs to catastrophic failure when subjected to high-temperature acid digestion, extreme thermal cycling, or concentrated hydrofluoric-nitric leach mixtures. As a specialized quartz distillation flask manufacturer and exporter serving Mongolia, Lianyungang Vulra Quartz Products Co., Ltd. provides engineered fused silica solutions engineered specifically to withstand rigorous mechanical wear and extreme temperature differentials.
Distillation and fractional thermal extraction of volatile elements (such as arsenic, antimony, selenium, mercury, and rhenium) from complex mineral concentrates require an apparatus with practically zero coefficient of thermal expansion, exceptional structural rigidity, and absolute chemical inertness. Our quartz distillation flasks, constructed from synthetic and natural quartz crystal sand sourced from the world crystal capital of Donghai, deliver an analytical baseline with trace element contamination below parts-per-billion (ppb) thresholds. This ensures that analytical methods including Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Atomic Absorption Spectroscopy (AAS), and X-ray Fluorescence (XRF) achieve uncompromising repeatability without silica or metallic background leaching.

Custom-fabricated quartz distillation apparatus tailored to the unique operational environments and industrial challenges of Mongolia’s strategic economic sectors.
In high-throughput mining assay laboratories across the Ömnögovi province, mineral samples undergo rigorous multi-acid decompositions. Our heavy-wall round-bottom quartz distillation flasks and flow-splitting units handle violent boiling of perchloric, nitric, and hydrofluoric acid combinations.
As Mongolia advances its crude oil refining infrastructure in Sainshand and the wider Dornogovi territory, ASTM-compliant quartz distillation flasks are vital for true boiling point (TBP) distillation, heavy hydrocarbon cracking, and sulfur recovery analysis without catalyst-poisoning contamination.
Exploration projects throughout Dornod and Central Mongolia targeting rare-earth elements (REEs) and in-situ recovery (ISR) uranium necessitate closed-loop quartz distillation vessels capable of handling superheated volatile fluorides and aggressive oxidant strippers.
The Mongolian Agency for Standard and Metrology (MASM), National University of Mongolia (NUM), and state geochemical repositories rely on our calibrated volumetric quartz flasks and distillation assemblies to maintain baseline analytical accuracy and standardize national mineral certifications.
Environmental monitoring authorities across the Orkhon and Tuul river basins utilize quartz Kjeldahl distillation units and cyanide/mercury distillation heads to assess mineral processing effluent, assuring rigorous compliance with stringent environmental protection statutes.
Exploratory drilling camps throughout the Altai and Khangai mountains operate under winter conditions reaching -35°C to -45°C. Vulra quartz distillation apparatus guarantees structural survivability when moved rapidly between sub-zero storage and open flame heating.
The industrial landscape of Mongolia is experiencing a transformative structural transition under the banner of the "Vision 2050" and "New Recovery Policy" development blueprints. Historically focused primarily on exporting raw unrefined ore, Mongolia is systematically investing in downstream value-addition—establishing domestic copper smelting plants, coal-washing infrastructure, synthetic fuel conversion projects, and advanced mineral processing complexes. This shift demands a radical modernization of testing and assay laboratories across the nation.
With smelters requiring precise real-time process control to regulate matte grades, slag chemistry, and gaseous emissions, analytical turnaround times must drop while accuracy thresholds tighten. Traditional borosilicate glassware, prone to thermal fatigue, microscopic scratching, and leaching of trace elements into digested solutions, represents an unacceptable liability in a modern automated laboratory. Leading geochemical facilities in Ulaanbaatar and private assay service providers are increasingly transitioning their digestion lines, mercury cold-vapor rigs, and volatile extraction circuits exclusively to high-purity fused quartzware. By partnering directly with a dedicated manufacturer, Mongolian facilities bypass intermediary distributors, securing custom dimensional tolerances, rapid replacement cycles, and guaranteed purity ratings directly from the production source.

Procuring fragile, high-precision laboratory quartzware from overseas has historically posed significant logistical hazards for Mongolian purchasing agents. The harsh overland transit through the Gobi desert, coupled with sub-zero winter temperatures, demands specialized export packaging and dependable shipping channels. Vulra Quartz provides direct, bonded multimodal logistics specifically optimized for Central Asian transit:
The Lianyungang–Erenhot–Zamiin-Uud Trade Route: As our primary manufacturing facilities reside in Lianyungang (the eastern terminus of the New Eurasian Land Bridge), we maintain direct freight access to China's primary border crossing into Mongolia at Erenhot / Zamiin-Uud. Consignments move smoothly via express bonded rail or containerized road freight straight into the Ulaanbaatar Customs Terminal (Ulaanbaatar Logistics Hub) with standard clearance transit times ranging between 7 to 12 operational days.
Zero-Breakage Export Packaging Protocol: Each quartz distillation flask is subjected to ultrasonic acid wash and cleanroom drying before being individually enclosed within high-density vacuum-formed EPE foam shells. These modules are nested within rigid multi-ply export cartons and secured inside fumigated plywood crates reinforced with exterior steel corner strapping, interior shock absorbers, and moisture-absorbing silica packs. Fragile items travel safely over unpaved regional roads to remote mine sites without structural micro-fissuring or joint misalignment.
Comprehensive technical and commercial clarifications addressed directly by our senior production engineers.
Our fused quartz flasks are constructed from 99.99%+ pure SiO₂ possessing an exceptionally low linear coefficient of thermal expansion (5.5 × 10⁻⁷ /°C). Unlike borosilicate glass which shatters under thermal differentials exceeding 120°C, high-purity quartz can easily survive a thermal delta exceeding 1000°C. Even if stored in unheated winter warehousing at -40°C in the Gobi desert and placed directly above an open heating mantle or gas burner, the flask will not crack or experience thermal spalling.
Yes. Custom engineering is our primary capability. We regularly produce custom quartz distillation equipment, multi-neck extraction vessels, Kjeldahl flasks, and specialized fractionation columns based on buyer-supplied 2D PDF sketches, CAD files, or physical reference samples. Our engineering team conducts a complimentary manufacturability review prior to quoting to confirm wall thickness integrity, joint tolerances, and stress annealing parameters.
We precision-grind all international standard ground joints including European Standard Taper joints (NS 14/23, 19/26, 24/29, 29/32, 45/40), American Standard Taper (ST), spherical ball-and-socket joints (S13, S19, S35), and high-vacuum threaded screw-cap fittings (GL-14, GL-18, GL-25, GL-45) with inert PTFE liners. Furthermore, joint ground faces can be fire-polished or left finely frosted depending on vacuum grease sealing specifications.
Standard laboratory glassware contains significant fluxing oxides including boron, sodium, potassium, and calcium, alongside trace iron and aluminum. Under superheated acidic digestion, these elements leach into solution, creating elevated background spectra and spectral interferences during ICP-MS or ICP-OES analysis. Vulra SJ-Grade quartz contains metallic impurities below 1.5 ppm across all critical metals (Fe < 0.2 ppm, Al < 8 ppm, Cu < 0.05 ppm), assuring flawless baseline accuracy for gold, silver, platinum-group elements, and rare-earth assays.
We support educational trials, metallurgical pilot tests, and OEM prototyping by offering a Minimum Order Quantity of just 1 piece for custom quartz distillation flasks, large round-bottom vessels, and specialty extraction bodies. Standard standardized tubing and small accessories typically start from 5 to 10 pieces. Complete catalog pricing and prototype lead times are provided within 24 hours of technical review.
Every commercial consignment exported to Mongolia is accompanied by an authenticated Certificate of Conformance (CoC), raw quartz material spectrographic chemical analysis sheets, CE compliance certificates, and dimension inspection verification reports. We also supply standard international shipping documentation, including Commercial Invoices, Packing Lists, Certificates of Origin (CO) under applicable trade frameworks, and multimodal transport waybills.
To avoid surface devitrification (the transformation of amorphous fused silica into crystalline cristobalite at high temperatures), quartz surfaces must remain free from alkali metals, fingerprints, and tap water residues. We recommend soaking used distillation flasks in a 10% nitric acid or aqua regia bath, followed by rigorous rinsing with ultra-pure deionized (DI) water (18.2 MΩ·cm) and lint-free drying in a dust-free enclosure before high-temperature thermal operation.
