DURAN wide-neck Erlenmeyer flask, 25 ml, pack of 10, DIN EN ISO 24450, 212261405

Easy to fill and clean thanks to the wide-neck design

With this set of 10, you receive DURAN ® Erlenmeyer flasks in the wide-neck version (25 ml). Unlike the narrow-neck version, this model features a significantly wider neck opening (31 mm). This not only makes it considerably easier to fill with powders and pasty substances, but also allows for more thorough and easier cleaning. Furthermore, the wide neck promotes better aeration of the sample, which is beneficial for certain microbiological cultures.

DURAN ® borosilicate glass 3.3 – Uncompromising quality

Manufactured from DURAN ® borosilicate glass 3.3 in accordance with DIN EN ISO 24450, these flasks offer the highest resistance to water, acids, saline solutions and organic solvents. The uniform wall thickness distribution guarantees mechanical robustness and excellent thermal shock resistance. They can be used without any problems on a hotplate or in an autoclave (121 °C / 134 °C).

Safety and traceability

The reinforced flanged rim provides additional stability around the mouth of the flask. Each flask is marked with a Retrace code, which enables complete batch traceability (certificate available online). The clearly legible scale, made of fired white ceramic, and the labelling field support efficient laboratory work.
