Description
Flat-bottom flask narrow neck, 250 ml, is a standing laboratory flask intended for everyday wet-chemistry handling where a stable base and a reduced neck opening are required. The narrow-neck Stehkolben format supports routine liquid holding, transfer and simple preparation steps on the open bench. This article is offered as a pack of 10 pieces, giving laboratories a convenient unit quantity for teaching sets, parallel sample work or general glassware replenishment. The nominal 250 ml capacity suits medium-volume tasks such as reagent aliquoting, intermediate storage during procedures and straightforward mixing that benefits from a flat, free-standing footprint. Flat-bottom geometry allows secure placement on work surfaces without extra supports, while the Enghals (narrow neck) profile helps limit splash and evaporation compared with wide-mouth vessels. Supplied from manufacturer Dinkelberg, the flasks fall under standard laboratory material classification and are produced with origin in the Czech Republic. Clear association with the 250 ml size aids quick identification in mixed inventories. Choose this ten-piece narrow-neck flat-bottom flask pack when protocols call for consistent standing flasks across multiple stations or student workplaces.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, flat bottom narrow-neck, 250ml, 10/PK
What is this article?
Flask, flat bottom narrow-neck, 250ml, 10/PK is the article on this page. Luminix Health distributes Dinkelberg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
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.
