We have round bottom flasks made from quality borosilicate 3.3 glass because it endures the wear and tear of long term laboratory use alongside accurate thermal and chemical stability. Equipped with a uniform spherical base and a short standard ground neck, these flasks work well for heating, boiling, and distillation operations executed in atmosphere or under vacuum.

Specification Of Round Bottom Flask

Product Code: 5001

Design: Round bottom, short neck, standard ground joint

Material: Borosilicate 3.3 Glass (thermally shocked beyond 165°C: resistance >165°C)

Capacity Range: 25ml – 10,000ml

Joint Sizes: 10/19 to 60/46, fully compatible with laboratory standards

Feature Of Round Bottomed Flask

● Wider walls enable better durability of the flasks when under vacuum or reflux use. 

● All of our flasks have a precisely ground joint providing an airtight connection without leakage regardless of temperature changes Chemical exposure and transparency is enhanced due to flame polishing. 

● Hot spot formation is reduced greatly due to our uniformly spherical design as well as even heating. 

● Multiple sizes available to satisfy different condenser or distillation setup requirements. 

● Compatible with heating mantles, rotary evaporators, and ring clamps.
