Flasks
Erlenmeyer flasks are a staple of laboratory equipment and are used for mixing, heating, storage and titrations. At LT Laborhandel, you will find high-quality glass Erlenmeyer flasks in various volumes and designs, tailored for professional use in laboratories, research, industry and education. These flasks offer excellent chemical resistance, clear graduations and high temperature resistance. Whether for routine work, analytical applications or teaching laboratories, our Erlenmeyer flasks stand for reliable quality and safe handling in day-to-day laboratory work.
DURAN narrow-neck Erlenmeyer flask, 50 ml, pack of 10, DIN ISO 1773, 212161707
A quick swirl and the solution is mixed, without anything spilling over: that is exactly what the Erlenmeyer flask is designed for. The Erlenmeyer flask from Duran is a classic piece of laboratory equipment: Its conical shape makes it easy to mix liquids by swirling, without the contents splashing out. Made from high-quality borosilicate glass 3.3, it offers excellent chemical resistance, virtually inert behaviour and high operating temperatures. Typical applications Preparing and mixing solutions by swirlingTitrations and quantitative analysesCultivation of microorganisms in shaking cultures (narrow-necked, with stopper)Heating and brief boiling of liquidsStorage with a stopper (narrow-necked) or easy filling and cleaning (wide-necked)Use in chemistry, microbiology, analysis and education Material and thermal properties Borosilicate glass 3.3 is largely resistant to water, acids, alkalis and most organic substances. The uniform wall thickness and low thermal expansion ensure high thermal shock resistance, the flask is therefore particularly suitable for applications involving high temperatures and rapid temperature changes. Narrow-neck or wide-neck? Select the appropriate neck shape above: Narrow-neck (to DIN ISO 1773): The narrow neck reduces evaporation and makes it easier to seal with a stopper, ideal for storage, titration and cultures. Wide-neck (to DIN EN ISO 24450): The wide opening makes it easier to fill, weigh in solids and clean. Graduation and Markings An easy-to-read, printed scale allows the fill volume to be estimated. The fired-on white ceramic print (scale and labelling field) is particularly resistant to abrasion and chemicals and withstands repeated autoclaving and rinsing. Standards Narrow-neck version in accordance with DIN ISO 1773, wide-neck version in accordance with DIN EN ISO 24450. Due to production constraints, some intermediate sizes are non-DIN/ISO sizes (marked accordingly in the size overview), but are technically equivalent.
