Product Description:
Flask Round Bottom 25ml B-19
25ml/ 50ml/ 100ml B-19 Ground Joint Mini Round Bottom Flask is an essential Flask Round piece of chemistry glassware ideal for small-scale chemical reactions, distillation, and heating. Constructed from high-quality borosilicate glass, this flask is extremely durable—the most chemically resistant glass available. It also features a frame with a Triple Scale Hydrometer and Test Jar, commonly used in Wine Making Equipment. This glass resists most chemicals and temperature changes. The B-19 is based Flask Round on the B19 neck size, compatible with standard laboratory fittings, such as adapters, stoppers, and condensers, all of which enable a reliable, leak-proof seal during distillation or any laboratory application.
This flask has a round bottom for even heating and a jacket for uniform heat Flask Round distribution, making it suitable for applications that involve a high level of heating, such as precise distillation processes, chemical reactions, and heating of small amounts of liquid in the laboratory.
Key Features: Flask Round Bottom 25ml B-19
- Crystal-clear glass construction with high play and shine: Made of high-quality borosilicate glass, the flask offers the best chemical resistance and heat-resistant shock.
- Round bottom style: Promotes even heat distribution for reduced risk of heat stress and safer heating or distilling.
- B-19 Neck: The standard B-19 neck fits various connecting laboratory apparatus, such as adapters, stoppers, and condensers, for tight, leak-free connections.
- Chemical resistant: Withstands a wide variety of chemicals, solvents, and reagents commonly found in a laboratory.
- Micro Distillations, Micro Reactions, and Micro Extractions: Perfect for small-scale operations where volumes are limited, from a few milliliters to no more than 10 to 20 liters.

Applications:
- Chemical Reactions: Great for small-scale chemical reactions that require even heat distribution.
- Distillation: Ideal for distillations that require proper condensation and vaporization.
- Heating: Used for heating small amounts of liquid or solution inside the lab.
- Educational: A useful tool for demonstrations in the lab.
