Erlenmeyer flask made of borosilicate glass 3.3 with fused-on sleeve NS 14.5/23

The compact Erlenmeyer flask with sleeve NS 14.5/23 is made of high-quality borosilicate glass 3.3 and is a versatile laboratory vessel for sample preparations, titrations, cultivations, and numerous general chemical tasks. This special glass is characterized by excellent thermal shock resistance , high chemical resistance , and outstanding transparency, ensuring the flask remains durable and reliable even under intensive use.

The robust, precisely fused sleeve with standard ground joint NS 14.5/23 enables an absolutely leak-proof, secure, and stress-free connection with a wide variety of ground joint components such as dropping funnels, condensers, adapters, or measuring instruments. This allows the Erlenmeyer flask to be easily integrated into modular glass apparatus and offers maximum flexibility in everyday laboratory work.

The uniform wall thickness ensures excellent mechanical stability, allowing the piston to be used reliably even when heated, on hot plates, or in water and oil baths. This makes it ideally suited for precise fluid work, analytical procedures, reaction steps, or solution preparation.

Whether in research , analysis , teaching or synthesis laboratories – this Erlenmeyer flask offers a durable, safe and professional solution for the highest demands in the laboratory.
