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.
This article belongs on Beaker & flask accessories, in Beakers & flasks.

Questions about Finger plunger , 100 ml, NS 29, 1 unit(s)
What is this article?
Finger plunger , 100 ml, NS 29, 1 unit(s) is the article on this page. Luminix Health distributes Kummer for laboratory use. It sits in Beaker & flask accessories, inside Beakers & flasks, in Labware.
Accessories for beakers and flasks are the cork rings, the covers, the joint clips and the holders that keep a flask upright or closed. A clip is what stops a ground joint from falling apart when it is inverted.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
