Round Bottom Flask – 100ml, Joint Size 14/23 (Borosilicate Glass)

This 100ml Round Bottom Flask is manufactured from high‑quality 3.3 borosilicate glass, offering excellent durability and performance for educational and laboratory use. Designed with a standard ground glass joint (14/23), it enables secure, leak‑free connections with condensers, adapters, and other laboratory apparatus.

The round‑bottom design allows for even heat distribution, making this flask particularly suitable for heating, boiling, reflux, and distillation experiments. Borosilicate glass is renowned for its superior chemical resistance and high thermal stability, enabling the flask to withstand repeated heating and cooling without cracking. This makes it ideal for regular use in school science laboratories and prep rooms.

With a compact 100ml capacity, this flask is perfect for small‑scale reactions, controlled demonstrations, and student practical work where precision and safety are essential.
