Custom OEM Quartz Petri Dish Factory & Exporters

Grade selection depends strictly on the operational optical spectrum and thermal environment. JGS1 (Synthetic Fused Silica) is synthetic, free of bubbles, and optimized for deep ultraviolet transmission (185–2500 nm). It is required for UV spectroscopy, excimer laser reactions, and UV confocal microscopy. JGS2 (Optical Fused Quartz) is manufactured from natural crystalline quartz and covers the UV-visible range (220–2500 nm), making it the standard cost-effective selection for high-temperature furnace viewing, acid digestion, and general analytical laboratory petri dishes. JGS3 (Infrared Grade Fused Quartz) has an ultra-low hydroxyl content (OH < 5 ppm) that eliminates the typical absorption band at 2730 nm, extending optical transmission out to 3500 nm for thermal infrared applications.

Our clear fused quartz petri dishes have a strain point of 1070°C, an annealing point of 1140°C, and a softening point of 1683°C. In standard oxidizing or inert atmospheres, they can be operated continuously at up to 1100°C–1150°C without geometric deformation. Short-term peak thermal spikes up to 1450°C are safely tolerated. However, prolonged operation above 1150°C in the presence of alkaline dust, sodium, or potassium can induce surface devitrification (transformation into crystalline cristobalite), which reduces transparency and thermal shock resistance.

Yes. We specialize in custom OEM/ODM manufacturing. We routinely produce petri dishes ranging from miniature cell analysis formats (diameter 25 mm × height 10 mm) up to industrial crystallizing dishes exceeding 300 mm in diameter. We can incorporate internal quartz divider walls for dual-organism co-culturing, precision-ground joint rims with clamp flanges for hermetic vacuum sealing, ground-glass frosted writing patches, and custom optical-window recessed bottoms (±0.02 mm thickness tolerance). Please provide your PDF, DWG, or STEP files for engineering evaluation.

For standard chemical and thermal dishes, our precision fire-polishing provides a smooth, non-wetting surface with an Ra between 1.0 and 2.0 nm. For advanced laser microscopy, high-content screening (HCS), and inverted fluorescence observation, we perform automated double-sided Chemical Mechanical Polishing (CMP) that achieves optical flatness of 1 to 3 interference fringes per inch (λ/4 to λ/2) and an ultra-fine surface roughness of Ra ≤ 0.5 nm, eliminating laser refraction distortion.

Yes. Fused quartz is completely inert to standard sterilization protocols, including repeated autoclaving at 121°C/134°C, dry-heat sterilization up to 500°C, ethylene oxide (EtO), and gamma irradiation. Chemically, quartz is impervious to almost all concentrated organic and inorganic acids (including nitric, sulfuric, and hydrochloric acid, as well as aqua regia and Piranha solutions). The only exceptions are hydrofluoric acid (HF) at any temperature and concentrated phosphoric acid (H₃PO₄) when heated above 150°C.

To support corporate R&D teams and academic research labs, our standard MOQ for custom quartz petri dishes starts as low as 1 to 5 pieces for prototype review. Standard catalog sizes often ship from inventory within 48 hours. Custom CNC or optical-grinding sample prototypes are typically manufactured and dispatched within 7 to 10 working days. Production volume orders (100 to 5,000+ units) typically run on a 3 to 4-week production cycle depending on flame-working complexity.

Every single quartz dish is individually acid-degreased, wrapped in dust-free optical tissue, sealed in a moisture-barrier bag, and cushioned inside custom-molded high-density polyethylene (EPE) shock-absorbing foam compartments. For air express and consolidated sea freight, batches are secured within export-grade, fumigation-free plywood shipping crates reinforced with corner metal angle protectors. Our packaging withstands vertical drop tests of 1.2 meters, ensuring intact delivery to overseas facilities across North America, Europe, and Asia.
