Description
Erlenmeyer flask, 25 ml, socket NS 14,5/23 is a conical laboratory vessel designed for mixing, heating, culturing and short-term storage of liquids in chemical, pharmaceutical and life-science applications. Produced from borosilicate glass 3.3, it delivers excellent resistance to chemicals and thermal stress, allowing safe use on hotplates, in autoclaves or under refrigerated conditions. The precision ground joint socket NS 14,5/23 ensures a standardised, gas-tight interface with stoppers, condensers, dropping funnels and other modular glassware. Nominal volume is 25 ml (0,025 l), diameter 42 mm and height 70 mm, providing a practical intermediate size for small-scale reactions and culture work. Net weight is 0,025 kg. Offered as a single piece from manufacturer Rettberg, the flask is routinely chosen for titrations, media preparation, microbial cultures and general sample handling. Its conical body permits vigorous swirling without risk of overflow while the narrow neck reduces evaporative losses and airborne contamination. Consistent wall thickness and accurate joint dimensions support reproducible results in research laboratories, teaching facilities and quality-control departments.

Questions about Erlenmeyer flask, 25 ml, socket size 14,5/23
What is this article?
Erlenmeyer flask, 25 ml, socket size 14,5/23 is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Erlenmeyer flasks, inside Beakers & flasks, in Labware.
An Erlenmeyer, or conical, flask has a flat base and a narrowing wall so a liquid can be swirled. It is the ordinary culture and titration flask. A baffled wall is a different article, used when the swirl must turn the liquid over.
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.
