Do not fill the flask with more than 2/3 of its volume and not less than 1/3 of its volume.

Please dry the outside of the boiling flask before heating.

Preheat the round-bottomed flask before use.

Standard grinding mouth.

Fine grinding.

The rounded interface of the round bottom flask is sturdy and easy to clean.

Heat Resistant and High Temperature Resistant: Annealed at 600 degree Celsius, it can be used in open fire.

This 2000 ml round bottom boiling flask is made of high quality high borosilicate glass material, which is a kind of special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability.

Fine production process, uniform wall thickness, smooth and clean, high transparency.

The bottom of the flask is spherical for more even heating.

High hardening temperature, not easy to chemical reaction with other substances, can be used for a long time.

The round-bottomed flask has a 24/40 standard conical frosted joint with a 24/40 glass stopper and joint clip to ensure good sealing. It can also be tightly connected with other glassware to achieve accurate experimental results.

• Plastic joint clip
• High-quality material, pressure and drop resistance, good sealing effect, and easy to take off.
• Metal clip
• Made of steel sheet, not easy to break, acid and alkali resistant.
• It can be used to fix the frosted mouth of glass instruments of standard caliber, which can effectively strengthen the air tightness of the reaction system of the frosted mouth connection and facilitate the use.
