Standard borosilicate glass handles routine laboratory work. Industrial scale processes demand more. When muffle furnaces cross 1000°C or semiconductor fabs require strict trace metal control, baseline glass fails.
Facilities operating at these limits specify high-purity fused silica (quartz). Goel Glass Inc manufactures these specialized quartz components, delivering the exact thermal stability and chemical purity required for advanced analytical chemistry, high-temperature synthesis, and wafer processing .
Fused Quartz Material Specifications
Engineers specify quartz to survive extreme operating conditions. Here is the baseline capability data:
| Specification | Technical Limit |
|---|---|
| Thermal Limits | Safe for continuous service up to 1100°C. Tolerates short-term spikes over 1400°C . |
| Thermal Shock | Near-zero thermal expansion prevents the glass from fracturing during rapid temperature drops . |
| Chemical Purity | Trace metal contamination stays in the parts-per-billion (ppb) range, meeting strict semiconductor-grade requirements . |
| Optical Clarity | Light transmission spans from deep UV (150 nm) through the visible and near-IR spectrums . |
| Chemical Inertness | Resists physical breakdown when exposed to aggressive acids, alkalis, and solvents . |
The Industrial Quartz Portfolio
Industrial quartz manufacturing covers distinct equipment categories. We engineer each classification to meet specific dimensional tolerances and analytical demands .
Standard Laboratory & Process Glassware
This line acts as a direct, high-purity replacement for conventional borosilicate glass when contamination control is strict .
- Conical & Round Bottom Flasks: Built for high-temperature synthesis and trace analytics. Conical flasks use flat bottoms (50ml to 2000ml). Round bottom versions scale up to 10,000ml or higher for preparative workflows .
- Beakers (Low & Tall Form): Designed for aggressive acid evaporation. Capacities start at 5ml laboratory sizes and reach 4000ml .
- Volumetric & Graduated Cylinders: Required for preparing ICP and ICP-MS standard solutions. Volumetric flasks (5ml to 2000ml) utilize interchangeable solid glass stoppers to maintain calibration accuracy .
Distillation & Purification Systems
Boiling aggressive acids in standard glass risks trace metal leaching. Quartz distillation assemblies eliminate this variable to ensure clean condensation .
- High-Purity Condensers: Configured in Liebig, Allihn, Graham (coil), and spiral forms. They integrate optimized heat-exchange surfaces and water connections, typically measuring 200mm to 600mm .
- Distillation Flasks: The primary heating vessels. They utilize long necks and side-arm vapor discharge tubes in single or multi-neck setups, spanning 125mL to 5L .
High-Temperature Furnace Ware
This hardware operates continuously inside muffle furnaces and thermal analysis systems at 1100–1200°C .
- Crucibles: Used for molten metals, calcination, and ash testing. The Volatile Matter Crucible uses a straight wall and flat base, built specifically for coal and carbon testing under ASTM standards .
- Muffle Trays & Combustion Boats: Muffle trays feature integrated circular openings (4, 6, or 8-hole setups) to hold crucibles . Combustion boats use a thick-wall, flat-bottom design with rounded edges to distribute heat evenly .
Custom Fabrication & OEM Components
Equipment manufacturers frequently need parts built to proprietary CAD drawings or physical samples.
- Core Capabilities: Fabricators build complex multi-component assemblies using fusion welding, flame-working, and controlled thermal bending. This includes hermetic joints and glass-to-metal graded seals .
- Specialized Hardware: The custom line covers reaction vessels, burners, precision-bent tubing, glass manifolds, infrared optical plates (Jgs3), and UV-resistant quartz rods .
Optical & UV Spectroscopic Applications
Analytical spectroscopy requires optical-grade, ultra-high purity fused quartz to prevent data distortion.
- Spectrophotometer Cuvettes: Fused bodies with polished quartz windows. They provide optical transmission from 170 to 2700 nm. The 10mm pathlength is standard. Sizes of 1mm, 2mm, 5mm, 20mm, and 50mm fit all standard cell holders .
- Optical Windows: Precision-polished circular, square, or rectangular windows. Designed for UV, IR, plasma, and photochemical systems needing high optical clarity
