VEVOR Round Bottom Flask 2000 ml Receiving Flask Borosilicate Glass Reaction Flask 2 Neck Boiling Flask with 24/40 Standard Taper Ground Joint, Flask Round Bottom for Vacuum Distillation Apparatus

Features:

• Premium Quality: This boiling flask pack is built with high-quality borosilicate glass, heat-resistant, sturdy, and durable. It is heavy-wall designed, made by hand blown process to ensure uniform wall thickness.
• Excellent Sealing: With the 24/40 standard taper ground joint, the round flask has excellent sealing and can be tightly combined with other glassware. It comes with two Keck clips to prevent the joints from separating.
• Uniform Heating: With the spherical bottom, this round glass flask has a larger heating surface than the flat bottom flask, so that the liquid can be heated or boiled more evenly. Its surface stress is also uniformly distributed.
• Clear & Transparent: The round borosilicate has a clear and transparent wall without protrusion, easy to observe the experimental phenomena, and liquid changes. The precise specification is marked for classification.
• Extensive Application: The round bottom glasses are indispensable in the distillation experiment and reflux process, which can withstand typical laboratory thermal variations in chemistry processes like heating and cooling.
