Borosilicate 3.3 Laboratory Glass Reactors (1L - 10L)
Goel Glass designs, engineers, and fabricates precision Borosilicate Glass 3.3 Laboratory Glass Reactors (available in standardized capacities from 1 Liter to 10 Liters, with custom vessels down to 100 mL). Specifically developed for chemical synthesis, pharmaceutical formulation, active pharmaceutical ingredient (API) research, and academic laboratories, these benchtop systems provide unparalleled chemical inertness, high thermal shock tolerance, and full 360-degree optical visibility for in-situ process monitoring.
Manufactured from certified Schott Duran® / Borosilicate 3.3 raw material conforming to DIN ISO 3585 standards, Goel Glass reactors are engineered to operate seamlessly within standard benchtop and walk-in fume hoods. Vessels can be configured in Single-Wall (unjacketed for atmospheric or heating mantle use), Double-Wall (jacketed for fluid circulation from external heating/cooling baths), and Triple-Wall (vacuum-jacketed outer envelope that prevents condensation and icing during cryogenic duties down to -50°C while minimizing ambient heat loss up to +180°C).
Standard Operating Parameters
- Standard Capacity Range: 1 L, 2 L, 3 L, 5 L, 10 L (Custom from 100 mL)
- Operating Temperature: -50°C to +180°C (-80°C to +200°C on request)
- Operating Pressure: Full vacuum (< 0.5 mbar) up to +0.5 bar (g)
- Wetted Contact Parts: Borosilicate Glass 3.3 & Virgin PTFE
- Agitator Speed Range: 40 to 400 RPM (Digital AC Geared Motor)
- Drainage Mechanism: Zero dead-leg flush bottom valve (PTFE plug)
Key Engineering Features
- Broad Chemical & Solvent Inertness: Process media contacts exclusively medical-grade Borosilicate 3.3 and virgin PTFE, eliminating trace metal leaching and resisting strong acids, halogens, and aggressive organic solvents (see Technical Information for caustic alkali limits).
- Precision Overhead Digital Agitation: High-torque geared motor with integrated digital speed display and stepless regulation (40–400 RPM). Compatible with interchangeable anchor, propeller, and turbine impeller geometries.
- Hermetic Shaft Sealing: Choose between low-friction virgin PTFE stuffing boxes, dynamic mechanical seals, or hermetic magnetic drive couplings for high-vacuum integrity.
- Zero Dead-Leg Flush Bottom Discharge: Contoured PTFE bottom valve seals flush with the vessel dish, preventing stagnant reagent pooling and solids settling.
- Permanent Graduation Markings: High-contrast, chemically resistant volumetric volume graduations fired permanently into the glass wall.
- Fume Hood Ergonomics: Lightweight, rigid 304/316 Stainless Steel skid frame with quick-release vessel support clamps for effortless glassware cleaning and interchange.
