DURAN narrow-neck Erlenmeyer flasks, 200 ml, pack of 10, DIN ISO 1773, 212163202

The universal laboratory standard, in a set of 10

With this pack, you receive 10 original DURAN ® Erlenmeyer flasks (narrow-necked) with a nominal volume of 200 ml. This size is particularly popular in everyday laboratory work, as it offers an ideal balance between ease of handling and sufficient volume for reactions and cultures. The classic conical shape in accordance with DIN ISO 1773 and the narrow neck minimise the risk of liquids splashing out when swirling or boiling.

DURAN ® borosilicate glass 3.3 – Maximum resistance

Manufactured from the tried-and-tested DURAN ® borosilicate glass 3.3, these flasks offer exceptional chemical resistance to acids, bases and organic solvents. Thanks to their excellent thermal shock resistance and mechanical robustness, they are ideally suited for direct heating on a hotplate as well as for repeated sterilisation cycles in an autoclave (up to 121 °C / 134 °C).

Traceable quality

To ensure your quality standards are met, each flask features a trace code that enables complete batch traceability. The clearly legible scale, made from fired white ceramic, aids quick measurement, whilst the labelling area allows for permanent marking. The reinforced flanged rim provides additional stability during handling.
