Description
Standing flask with white graduations, 4000 ml capacity and NS 29/32 ground joint is a durable laboratory vessel made from heat-resistant borosilicate glass in accordance with DIN EN ISO 4797. Supplied without a stopper, this flat-bottom flask combines a thick wall, heavy base and reinforced rim to reduce the risk of breakage during cleaning, handling and transport. Perfectly ground standard taper necks with a smooth interior provide a reliable, leak-tight seal when used with matching joints or stoppers. Volume markings and inscriptions are printed in durable white enamel for clear, long-lasting readability. Suitable for heating, mixing, temporary storage and general preparative work, the flask from manufacturer ISOLAB Laborgeräte supports routine chemistry and process applications where thermal stability and mechanical robustness are required. The generous 4000 ml working volume makes it well suited to larger-scale reactions, distillations and bulk solution handling in research, teaching and quality-control laboratories. Its stable standing design allows safe placement on the bench or heating equipment without additional support.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - flat bottom - glass - clear - NS neck - 4000 ml - NS29/32
What is this article?
flask - flat bottom - glass - clear - NS neck - 4000 ml - NS29/32 is the article on this page. Luminix Health distributes ISOLAB 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.
