Description
Round-bottom flask, white graduated, 2000 ml with NS 29/32 ground joint is a laboratory vessel manufactured from heat-resistant, durable borosilicate glass according to DIN EN ISO 4797. Its thick wall, heavier base and reinforced rim reduce the risk of breakage during cleaning and transport. Perfectly ground NS necks with a smooth interior ensure a leak-tight seal with compatible stoppers or joint adapters. Quantity divisions and lettering are applied in white enamel for durable, high-contrast visibility. The flask is supplied without stopper and serves well as a distillation flask, receiving vessel or general-purpose heating flask where the rounded base promotes uniform heat transfer. From manufacturer ISOLAB Laborgeräte, the design balances mechanical strength with the thermal endurance typical of borosilicate laboratory glassware. Offered as a single piece, this 2000 ml round-bottom flask with standard NS 29/32 joint supports medium-scale preparative work, reflux setups and collection tasks in chemical, pharmaceutical and research laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - round bottom - glass - clear - NS neck - 2000 ml - NS29/32
What is this article?
flask - round bottom - glass - clear - NS neck - 2000 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.
