Features & Details
- 【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.
Key Features
-
Thickened Borosilicate Glass
The spherical flask is made of borosilicate glass with a massive wall, featuring high-temperature resistance and a low expansion rate.
-
24/40 Taper Ground Joint
The flask is designed with the 24/40 standard taper joint, providing excellent sealing performance for its frosted inner surface.
Spherical Bottom Design
The spherical bottom design is adopted to disperse the surface force evenly, making it more resistant to fracture under vacuum.
High Transmittance
With the smooth and bubble-free surface, the organic glassware has a high transmittance, convenient to observe the experiment.
Two Keck Clips
Two Keck clips for 24/40 joints are provided to effectively prevent the solution from splashing out and reduce the liquid evaporation.
Widely Used
This chemistry lab glassware is widely used in organic chemistry, as the distillation and receiving flask in the vacuum distillation apparatu
Round Bottom Flask
The round bottom flask stand is made of heat-resistant borosilicate glass with a massive wall, making it sturdy and durable. The flasks around the neck are equipped with the 24/40 standard taper joints with the frosted inner surface, which have excellent sealing without any leakage. With stable performance, this cork stand round bottom flask is widely applied in organic chemistry.
