DURAN narrow-neck Erlenmeyer flasks, 300 ml, pack of 10, DIN ISO 1773, 212163905

More volume capacity in the set of 10

This pack contains 10 DURAN ® Erlenmeyer flasks with a nominal volume of 300 ml. This intermediate size is particularly practical when the standard volume of 250 ml is too small for foaming reactions or intensive mixing processes, but a 500-ml flask would take up too much space in the incubator or on the shaker. The conical shape and narrow neck (DIN ISO 1773) ensure safe swirling without splashing.

Borosilicate glass 3.3 – The benchmark for durability

Like all Original DURAN ® laboratory glassware, these flasks are also made from high-quality borosilicate glass 3.3. The material is highly chemically resistant to water, acids, salt solutions and organic solvents. Thanks to their robust wall thickness and high thermal shock resistance, the flasks can be heated directly on hotplates and repeatedly autoclaved at 121 °C or 134 °C.

Functionality and traceability

Each flask is marked with a Retrace code, which enables complete batch documentation (certificate available online). The reinforced flanged rim increases the mechanical stability of the mouth. The durable white ceramic scale and the large labelling area facilitate the identification and handling of your samples.
