Description
Flat-bottom flask 50 ml with standard ground joint is a compact laboratory vessel fabricated from borosilicate glass 3.3 and fitted with an NS 29/32 ground joint sleeve. Built to DIN EN ISO 4797 with a short neck, it provides a stable flat base for small-scale reactions, titrations and sample preparation on the laboratory bench. The 50 ml nominal volume is well suited to micro-scale synthesis, reagent aliquoting and analytical work-up where minimal dead volume and easy handling are advantageous. Borosilicate glass 3.3 ensures high chemical durability and resistance to thermal shock, supporting repeated heating and cooling cycles. The precision NS 29/32 joint guarantees reliable, leak-free connections to matching glassware components. Offered by manufacturer Marienfeld in packs of 10 pieces packed in cartons, these flasks are convenient for stocking multiple workstations. The short-neck configuration simplifies addition of solids or liquids, swirling and thorough cleaning after use. Combined with the secure flat bottom, the design delivers dependable performance for teaching laboratories, quality-control routines and research applications requiring robust, reusable small-volume glassware of consistent dimensional quality.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks 50 ml with round bottom and ground joint
What is this article?
Boiling flasks 50 ml with round bottom and ground joint is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Matériel de laboratoire.
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.
