DURAN narrow-neck Erlenmeyer flask, 125 ml, pack of 10, DIN ISO 1773, 212162806

DURAN ® Quality for everyday laboratory use: a set of 125 ml Erlenmeyer flasks

This pack contains 10 high-quality DURAN ® Erlenmeyer flasks with a narrow neck and a nominal volume of 125 ml. Thanks to its tried-and-tested conical shape, this flask is the standard vessel for titrations and mixing processes: it allows the sample to be swirled vigorously without any liquid escaping. The 125 ml volume provides an ideal intermediate size between the standard 100 ml and 200 ml sizes, which is particularly advantageous for specific reaction set-ups.

Borosilicate glass 3.3 – Extremely resistant and durable

Manufactured from DURAN ® borosilicate glass 3.3, these flasks are characterised by excellent chemical resistance to water, acids, salt solutions and organic solvents. The uniform wall thickness ensures mechanical stability and excellent thermal shock resistance. This makes the flasks ideally suited for heating on a hotplate as well as for regular sterilisation cycles in an autoclave.

Safe handling and traceability

The reinforced flanged rim increases break resistance in the neck area, whilst the white ceramic scale allows for quick volume estimation. A large labelling area facilitates sample identification. Each flask is also provided with a Retrace Code, which allows you to access the batch certificate online at any time – a must for quality-related documentation.
