Specification list
Heavy Wall 3-Neck Round Bottom Flask is a professional high-strength laboratory glass container designed for complex chemical synthesis, reflux, distillation and high-load reaction experiments. It is configured with standard outer taper joints for the center neck and two side necks, perfectly compatible with various standard laboratory glassware and accessories. Equipped with a built-in 4mm straight bore PTFE stopcock drain, the flask supports convenient liquid draining and sample release without disassembly. It is an essential precision glassware for chemical, pharmaceutical and new material research laboratories.
Key Features:
● Reinforced Heavy Wall Construction: Made of thickened heavy wall glass material, the flask features excellent mechanical strength, high temperature resistance and pressure resistance. It is not easy to deform or crack during high-temperature heating and vacuum reaction, effectively adapting to harsh laboratory experimental conditions and ensuring long-term safe use.
● Standard Taper Outer Joints: All center and side necks adopt universal standard outer taper joints, which can be tightly matched with stirrers, thermometers, condenser tubes, dropping funnels and other lab accessories. It ensures excellent airtightness and compatibility for multi-functional combined experiments.
● PTFE Stopcock: Equipped with 4mm straight bore PTFE stopcock drain. PTFE material features extreme chemical inertness, resisting corrosion of strong acid, strong alkali and various organic solvents. The straight bore design ensures smooth liquid drainage, no residue, no blockage, and supports precise flow control.
● Reasonable Round Bottom Design: The standard round bottom structure ensures uniform heating during oil bath, water bath and electric heating mantle operation, avoiding local overheating. It is conducive to full material reaction, stirring mixing and solution reflux, meeting various synthetic experimental requirements.
● Multi-Functional & Easy Operation: Three-neck multi-port design realizes simultaneous feeding, stirring, temperature detection and reflux reaction. The bottom PTFE drain enables fast and clean liquid discharge, greatly improving experimental efficiency and simplifying post-experiment cleaning work.Item Center Joint Side Joint Capacity CS-F42441L 24/40 24/40 1000ml CS-F42442L 24/40 24/40 2000ml CS-F424450 24/40 24/40 500ml CS-F42542L 45/50 24/40 2000ml CS-F42581L 45/50 24/40 1000ml CS-F42841L 29/42 24/40 1000ml CS-F42842L 29/42 24/40 2000ml CS-F428450 29/42 24/40 500ml
