Industrial Glassware
Jacketed Glass Vessel Systems
Goel Glass Inc. designs, engineers, and fabricates industrial-grade Borosilicate Glass reactor systems and jacketed vessels engineered for demanding chemical synthesis, crystallization, dissolution, and distillation processes. Operating with complete transparency, our reactor systems provide total visual observation of process phenomena, liquid phases, color transitions, and solid suspension.
Vessel Configurations & Capacities:
- Cylindrical Jacketed Vessels: Standard capacities of 10L, 20L, 30L, and 50L. Fitted with a sealed Borosilicate Glass outer glass jacket designed for efficient circulation of heat transfer fluids (hot water, thermal oil, chilled glycol).
- Spherical Reaction Vessels: Standard capacities of 5L, 10L, 20L, 50L, and 100L (with custom configurations available up to 200L). Ideal for multipurpose reaction, distillation boiling, and liquid holding.
- Benchtop Laboratory Reactors: Single, double, and triple-walled reactors from 0.5L to 5L for laboratory R&D and scale-up studies (see Benchtop Lab Reactors).
Every vessel is engineered with precision Schott/QVF-compatible buttress flanges, multiple top nozzles for feeding, condensing, reflux dividing, and instrumentation, and a zero-dead-volume flush bottom outlet valve (DN25 / DN40) equipped with chemically inert PTFE bellows sealing.
Key Technical Parameters:
- Operating Pressure: Full vacuum (-1.0 bar g) with positive pressure ratings governed by vessel geometry and size: up to +0.5 bar g for vessels ≤50L, and +0.4 bar g for 100L spherical vessels (in accordance with ISO 3585 / BS EN 1595 standard ratings). In assembled reaction systems, maximum permissible pressure is always governed by the lowest-rated component limit.
- Operating Temperature: -50°C to +200°C (-58°F to 392°F), with maximum allowable thermal shock differential ΔT ≤ 50°C.
- Material Construction: High-purity Borosilicate Glass (DIN ISO 3585 / ASTM E438 Type I, Class A) with PTFE/FFKM contact wetted components.
- Agitation & Sealing: The stirrer shaft is 10 mm in diameter and will be inserted directly into the motor drive. Instead of a magnetic coupling, we offer high-performance PTFE stuffing guides from Cowie (imported from the United Kingdom), providing superior chemical resistance and dependable vacuum-tight sealing for turbine, anchor, or propeller agitators driven by flameproof or VFD-controlled electric motors.
Your frequently asked question
Yes, Goel Glass supplies both standard catalog configurations and custom-engineered reaction systems. Standard spherical vessels are available from 5 L to 100 L, while cylindrical jacketed vessels are offered from 10 L to 50 L (and benchtop scales from 0.5 L to 5 L). We customize nozzle numbers, nominal sizes (DN25 to DN200), joint styles (buttress, spherical, or flat flange), baffle insertions, and support framework geometries to suit your exact facility and process requirements.
Key selection criteria include required batch processing volume, process temperature range (-50°C to +200°C) and allowable jacket differential (ΔT ≤ 50°C), vacuum rating (-1.0 bar g), heat transfer area requirement, agitation viscosity and solids-handling demands, head-space and condenser duty, and chemical compatibility of all wetted PTFE and FFKM gasket materials.
