Product Description

The Flask Round Bottom 2 Neck B-Series is constructed of quality borosilicate glass, which means it can withstand heat, thermal shock, and chemical corrosion. The round bottom is for uniform heating, suitable for lab use.
Fitted with two neck joints, it is excellent for experiments requiring a double-necked flask for connections such as stoppers, adapters, and condensers. The standard taper joints, (B-24, B-29, and B-34, depending on size) provide a secure, leak-proof connection for many laboratory operations such as chemical reactions, distillation, and other operations requiring heating.
Excellent for small laboratory applications and for medium-scale industrial applications, 50mm to 5000ml capacities available for a 2-neck flask.
