DURAN narrow-neck Erlenmeyer flask, 50 ml, pack of 10, DIN ISO 1773, 212161707

Genuine DURAN ®-quality in a handy set of 10 This set contains 10 high-quality DURAN ® Erlenmeyer flasks (narrow-neck) with a nominal volume of 50 ml. The classic conical shape is ideal for precise laboratory work such as titrations or the gentle mixing of small sample volumes. The narrow-neck design minimises the risk of spillage when swirling and reduces the loss of volatile substances. Maximum durability thanks to borosilicate glass 3.3 Manufactured from DURAN ® borosilicate glass 3.3, these flasks offer exceptional chemical resistance and high thermal stability. They are resistant to thermal shock and are ideal for use on hot plates and for sterilisation in autoclaves (up to 121 °C or 134 °C). The robust wall thickness and reinforced flanged rim guarantee a long service life in everyday laboratory use. Safety and Documentation To ensure quality assurance, each flask bears a trace code, which enables complete traceability of the production batch. The fired white ceramic labelling field allows for permanent marking of samples, whilst the easy-to-read scale provides a quick guide to volume.
