Description
Round-bottom flask with standard ground joint NS 14/23, LBG 3.3, 5 ml is a small-capacity borosilicate flask for microscale synthesis, distillation, and sample collection. Produced from borosilicate glass 3.3, it offers the chemical durability and thermal resistance needed for careful heating and cooling of limited volumes. The integrated standard ground joint NS 14/23 enables direct, leak-resistant connection to condensers, adapters, drying tubes, and other NS 14/23 components without additional sleeves in many setups. Nominal volume is 0,005 l (5 ml), ideal for method development, precious reagents, and analytical-scale work where minimal hold-up is important. Supplied as 1 piece from manufacturer Labbox, this flask fits compact reaction blocks, micro heating mantles, and small rotary evaporator assemblies when correctly clamped. Application areas cover round-bottom flasks, ground-joint flasks, distillation flasks, and receiving flasks. LBG 3.3 glass supports repeated thermal cycling under controlled laboratory conditions. Net weight is 0,016 kg. Precise joint geometry helps maintain alignment and vacuum integrity in closed systems.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask round bottom, LBG 3.3, mouth 14/23, 5 ml
What is this article?
Boiling flask round bottom, LBG 3.3, mouth 14/23, 5 ml is the article on this page. Luminix Health distributes Labbox 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.
