| 1 | Single-Wall Batch Quartz Reactor | Laboratory synthesis, digestion, small-scale chemical reactions, and thermal experiments. | 100 mL–20 L | High-purity fused quartz or fused silica; SiO₂ typically ≥99.9% | Flat or round bottom, removable cover, multiple ports, thermometer or thermocouple port, and optional drain valve. | Request the quartz grade, chemical composition, dimensional tolerances, surface-finish requirements, and inspection report. ASTM references should match the specific quartz product and application. | Verify that the manufacturing or supplying organization holds a current ISO 9001 certificate covering the relevant scope; ISO 9001 is a quality-management certification, not a quartz-material grade. | For powered equipment or a complete assembly sold in the European Economic Area, confirm applicable EU directives, risk assessment, technical file, declaration of conformity, and CE marking. A standalone glass vessel may not independently require CE marking. | Choose this format when flexibility, easy cleaning, and low-to-medium batch volume are more important than continuous operation. |
| 2 | Jacketed Quartz Reactor | Temperature-controlled reactions, crystallization, polymer work, and exothermic or endothermic laboratory processes. | 250 mL–50 L | High-purity fused quartz for the process vessel; Borosilicate or metal jacket may be used separately | Heating or cooling jacket, circulation connections, pressure-relief provision, agitator port, and temperature monitoring. | Obtain separate material documentation for the quartz process chamber, jacket, seals, fittings, and wetted components. Material traceability is especially important where aggressive chemicals are used. | Check whether the ISO 9001 scope includes glass or quartz process equipment, welding or fabrication where applicable, testing, and final inspection. | Assess the complete system rather than the quartz tube alone. Electrical controls, pumps, heaters, pressure equipment, and machinery functions may introduce additional CE requirements. | Best for buyers needing repeatable thermal control and reduced risk of direct heating of the reaction liquid. |
| 3 | Photochemical Quartz Reactor | UV photolysis, photocatalysis, advanced oxidation, water treatment studies, and light-initiated synthesis. | 100 mL–10 L | UV-transparent fused quartz; Select low-impurity material for UV transmission | Immersion well or external lamp chamber, UV shielding, cooling provision, sampling port, and controlled exposure geometry. | Request UV-transmission data at the intended wavelength, quartz grade, wall thickness, and optical inspection results. ASTM test methods may be used for selected optical or physical properties, but the exact standard must be stated. | Confirm controlled procedures for optical inspection, dimensional checks, lamp integration, and final assembly testing within the supplier’s ISO 9001 quality system. | UV lamps, electrical controls, shielding, interlocks, and enclosure design should be reviewed for applicable CE requirements. UV radiation protection must be addressed in the technical documentation. | Prioritize verified wavelength transmission and safe shielding; ordinary laboratory glass is not an equivalent substitute for UV applications. |
| 4 | Gas-Sparged Quartz Reactor | Gas–liquid reactions, oxidation, hydrogenation research, fermentation studies, and stripping experiments. | 500 mL–30 L | High-purity fused quartz with chemically resistant seals; Quartz wetted path preferred | Gas inlet diffuser, outlet condenser or scrubber connection, pressure gauge port, sampling port, and optional mechanical stirring. | Verify quartz composition, thermal-shock characteristics, port dimensions, and compatibility of gaskets and valves. Non-quartz components should have their own material certificates where required. | Confirm documented incoming inspection, leak testing, pressure or vacuum testing, and calibration control for gauges and flow-control components. | Determine whether the assembly falls within machinery, electrical, EMC, or pressure-equipment requirements. Do not assume CE marking applies solely because the vessel is made from quartz. | Specify the intended gas, operating pressure, vacuum condition, temperature, flow rate, and failure-protection measures before purchasing. |
| 5 | High-Temperature Quartz Tube Reactor | Catalyst screening, pyrolysis, thermal decomposition, gas-phase chemistry, and controlled-atmosphere experiments. | 25 mm–150 mm internal diameter; custom heated length | Fused quartz tube suitable for elevated-temperature service; High thermal-shock resistance required | Tube furnace or external heating zones, gas fittings, thermocouple access, ceramic supports, and optional multi-zone temperature control. | Request dimensional tolerances, wall thickness, maximum recommended operating temperature, thermal-shock information, and inspection records. The actual temperature limit depends on geometry, atmosphere, stress, and heating rate. | Check quality procedures for tube straightness, concentricity, surface defects, furnace calibration, temperature uniformity, and final leak testing. | Heaters, controllers, furnace enclosures, electrical protection, and control software may require CE assessment as part of the complete equipment package. | Match tube dimensions and temperature profile to the furnace; rapid heating, cooling, or mechanical stress can cause quartz failure. |
| 6 | Vacuum Quartz Reactor | Low-pressure synthesis, vacuum drying, thin-film or surface-treatment research, and oxygen-sensitive reactions. | 250 mL–20 L | Fused quartz designed for vacuum service; Geometry and wall thickness are critical | Ground or flanged connections, vacuum gauge port, controlled gas backfill, cold trap connection, and protective implosion shielding. | Request vacuum-rating information, dimensional drawings, visual-inspection criteria, leak-test results, and documentation for seals, flanges, and valves. ASTM material references alone do not establish a vessel’s safe vacuum rating. | Verify documented vacuum testing, traceability of critical components, nonconformance control, and calibration of vacuum measurement equipment. | Review the complete installation for applicable pressure-equipment, machinery, electrical, and EMC requirements. Include shielding and safe operating instructions in the technical file. | Use only a design specifically assessed for the intended vacuum level; atmospheric-pressure glassware should not automatically be used under vacuum. |
| 7 | Continuous-Flow Quartz Reactor | Process development, catalyst testing, water-treatment studies, scale-up experiments, and high-throughput screening. | 10 mL–10 L working volume; flow rate is process-dependent | High-purity fused quartz flow channel or tube; Select material for chemical and thermal compatibility | Defined inlet and outlet geometry, static mixer or packing section, sampling points, pressure monitoring, and optional heating or UV module. | Request quartz grade, internal-surface specifications, dimensional tolerances, flow-path inspection, and chemical-compatibility data for all wetted parts. ASTM references should be linked to the actual material or test method used. | Confirm documented process controls for machining, joining, leak testing, flow verification, cleaning, and final inspection. Ensure the ISO 9001 certificate is current and independently verifiable. | Assess the integrated pump, heater, UV source, sensors, control panel, and software against applicable EU requirements. CE status should be supported by a declaration of conformity for the complete applicable assembly. | Define residence time, pressure drop, flow regime, heat-transfer requirements, and cleaning method before selecting the reactor geometry. |
