• 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
