Product Description

The Flask Round Bottom 4 Neck B-Series is made from high-quality borosilicate glass, designed to withstand heat, thermal shock, and chemical corrosion. Its round bottom design ensures uniform heating, making it suitable for a wide range of laboratory applications.

Equipped with four neck joints, this flask is ideal for experiments requiring multiple apparatus connections such as condensers, funnels, stoppers, and adapters. The standard taper joints (B-24, depending on size) provide a secure, leak-proof connection for chemical reactions, distillation, and heating procedures.

Available in capacities from 250ml to 1000ml, the 4-neck flask is an essential tool for both small laboratory setups and medium-scale industrial applications.
