High-quality glass flasks for laboratory measurements and chemical reactions.
Glass Flask Overview
The Glass Flask product line offers a variety of laboratory flasks made from high-quality borosilicate glass. These flasks are designed for chemical reactions, mixing, heating, distillation, and storage tasks under diverse lab conditions. Typical designs include round-bottom, flat-bottom, volumetric, Erlenmeyer, and multi-neck variants, all integrating standard ground-glass joints for modular connectivity. Goel Scientific ensures compliance with international glass standards (such as DIN ISO 3585 and ASTM E438) and offers customization (neck sizes, neck count, dimensions) to accommodate specific laboratory requirements.
Specifications
• Material: Borosilicate glass 3.3 (chemical resistance, thermal stability)
• Volume range: 50 mL up to ~20 L (depending on flask type)
• Neck types: 1-, 2-, 3-, or multi-neck configurations with standard taper joints (e.g., 24/29, 29/32, 34/35)
• Joint quality: precision-ground surfaces for gas-tight sealing
• Wall thickness: designed to accommodate moderate heating and cooling cycles
• Temperature range: approximately –50 °C to +200 °C (typical for borosilicate)
• Optional customizations: extra ports, angled sidearms, widened necks, thicker walls for durability
Applications
• Reactions (heating, reflux, distillation) in academic and R&D labs
• Solvent boiling, condensation loops, and intermediate reaction steps
• Mixing and blending of reagents under controlled conditions
• Storage of solutions under inert or ambient atmospheres
• Generation of gas sprayers or liquid dispensers when paired with adapters
Because flasks are versatile, they serve as foundational components in chemical synthesis, analytics, educational labs, and pilot setups.
