Round flasks,DURAN®, transparent glass, 25 ml, NS 19/26, 1 unit(s)

Round flask DURAN®, transparent glass, 25 ml is a compact single-neck laboratory vessel with ground joint NS 19/26 for small-scale distillation, reflux and sample preparation. The round-bottom geometry supports uniform heating and stirring in micro- to small-volume work, while the NS 19/26 joint connects directly to standard condensers, adapters and stoppers. Made from DURAN® transparent glass, the flask combines chemical resistance with clear visibility of reaction mixtures and boiling behaviour. This round flask from manufacturer Lenz suits environmental analysis workflows, sampling steps and distillation or Soxhlet-related glassware trains where limited sample volumes are processed. Offered as one piece weighing 0,029 kg, the 25 ml capacity is ideal for scouting reactions, method development and teaching experiments that require economical use of reagents. The lightweight, single-neck format integrates easily into compact apparatus assemblies on laboratory stands. Visual monitoring through the transparent wall helps operators track colour changes, phase separations and evaporation throughout the procedure.
