Because\nof the spherical bottom, cork rings are needed to keep the round bottom flasks\nupright. When in use, round-bottom flasks are commonly held at the neck by\nflask clamps on a stand. The flasks are usually used in heating or boiling a\nliquid, in distillation as distilling flasks and receiving flasks for the\ndistillate, used as the distilling flasks in rotary evaporators. Laboy glass\nflasks are heavy wall designed, made by hand-blowing to ensure uniform wall\nthickness, made of high-quality borosilicate glass and annealed at 800 degree\nCelsius, can be heated directly in an open flame and can withstand typical\nlaboratory thermal variations in Chemistry processes like heating and cooling.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eHeavy-Wall Borosilicate Glass Construction Crafted from premium 3.3 borosilicate glass with thick walls (3.55mm) for superior thermal and mechanical strength.
