The laboratory classic in a value pack of 10

With this set, you receive 10 high-quality DURAN ® Erlenmeyer flasks (narrow-neck, 25 ml) for professional laboratory use. The tried-and-tested conical shape is ideal for titrations, preparing cultures or mixing processes, as it allows vigorous swirling without spilling. The nominal volume of 25 ml complies with DIN ISO 1773.

DURAN ® borosilicate glass 3.3 – Maximum durability

All 10 flasks are manufactured from the special glass DURAN ® Borosilicate 3.3. This material guarantees maximum chemical resistance to water, acids and many solvents. Thanks to their uniform wall thickness, the vessels are mechanically robust and possess excellent thermal shock resistance, making them ideal for use on hot plates or in autoclaves.

Quality and traceability

Each flask features an easy-to-read scale, a white ceramic labelling field and a Retrace Code, which enables full traceability of the batch. The reinforced flanged rim provides additional stability during handling and cleaning.
