Description
Finger plunger, 100 ml, NS 29 is a laboratory glassware accessory intended for round flasks and related vessels that carry a matching ground glass joint. With an NS 29 joint, it aligns with widely used European standard taper dimensions, enabling a secure mechanical interface on compatible flasks. The 100 ml rating addresses typical bench-scale volumes encountered in organic synthesis, solvent handling, and preparative work. Offered as one piece per pack, the plunger is practical for dedicated setups or as a spare for busy teaching and research laboratories. Users employ finger plungers where manual control of displacement or sealing within a jointed assembly is required without complex auxiliary hardware. This model comes from manufacturer Kummer and fits naturally alongside other round flasks and ground-joint consumables in the same size class. The simple construction supports routine cleaning and long service life under normal chemical laboratory practice. Specifying the NS 29 and 100 ml combination helps maintain interchangeability across multi-neck flasks, receivers, and adapters already present in the glassware inventory. Select this finger plunger to complete or renew NS 29 assemblies used for everyday preparative and instructional chemistry.
