For the chemists, home distillers, or serious science enthusiasts out there, this is a classic piece of lab glassware. It's a 2000ml (2-liter) round bottom flask with TWO necks, each featuring a standard 24/40 ground glass joint. The double necks are super useful because you can attach multiple pieces of equipment at once – like a condenser in one neck and a thermometer or addition funnel in the other. It's made from high-quality borosilicate glass (the good stuff, often called Pyrex-type), which means it can handle thermal shock and direct heat from a Bunsen burner or heating mantle. Perfect for reflux setups, distillation, chemical reactions, or just as a sturdy boiling flask. Dinglab is a known brand for lab glass. Remember, this is just the flask; you'll need clamps and a stand to hold it safely. A fundamental and versatile tool for any home lab or educational setting.
