Description
Steep-shoulder bottles 250 ml with narrow neck are clear laboratory reagent bottles fitted with a ground joint NS 19/26 and matching NS glass stopper. Made from soda-lime glass, they offer a practical nominal volume of 0,25 l for storing, dispensing and handling reagents, solvents and standard solutions in analytical and preparative work. The steep-shoulder profile combined with the narrow neck supports controlled pouring and reduces evaporation when the stopper is seated. Clear glass allows easy visual inspection of contents and fill level during routine laboratory use. These bottles from manufacturer Witeg suit general chemistry, quality control and teaching laboratories where reliable ground-joint closure is required. Supplied as a pack of 10 pieces, they integrate readily into existing glassware sets that use the NS 19/26 standard. The robust soda-lime construction provides everyday durability for aqueous and many organic media under normal laboratory conditions, making the bottles a dependable choice for sample storage, reagent preparation and transfer tasks.
