Description
Round-bottom flask 50 ml NS 29/32 brown stained is a laboratory glass vessel for distillation, collection and general reaction work where a spherical base and standard ground joint are required. The flask offers a nominal volume of 50 ml (0,05 l) with a single medium neck finished as NS 29/32, allowing secure connection to condensers, adapters and other ground-joint glassware. Outer diameter is 51 mm and overall height is 100 mm, giving a compact footprint suitable for heating mantles, oil baths and standard lab stands. Manufactured from borosilicate glass 3.3, the body combines thermal shock resistance with chemical durability for routine organic and analytical procedures. The brown-stained finish helps protect light-sensitive contents during storage or processing. Neck configuration is a single centre neck, supporting straightforward assembly of distillation and receiver setups. Supplied in packs of 10 pieces from manufacturer Witeg, this brown round-bottom flask is a practical consumable for teaching labs, quality control and preparative chemistry where NS 29/32 compatibility and reduced light transmission are both needed.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 50 ml ST 29/32 amber stained
What is this article?
Round bottom flask 50 ml ST 29/32 amber stained is the article on this page. Luminix Health distributes Witeg 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.
