Description
Single neck flask, PFA, 250 ml, NS 29/32 is a laboratory round flask intended for ground-joint assemblies in everyday lab practice. Fabricated from PFA, it carries a single neck with an NS 29/32 ground joint for reliable connection to condensers, distillation heads, adapters and matching stoppers. The 250 ml nominal capacity supports medium-scale sample work, reaction mixtures and general handling tasks where a polymer flask is specified instead of glass. The item is offered as 1 pc and weighs 0,080 kg according to the product data. It belongs to the group of round flasks and flasks with ground glass joints, providing a stable round body and a standardised joint interface for heating, mixing or short-term holding of laboratory media. This single neck flask from manufacturer Bohlender fits laboratories that already work with NS 29/32 systems and require a 250 ml PFA vessel for routine procedures. Clear joint sizing and defined volume help keep set-ups consistent across benches and instruments that share the same ground-joint standard.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Single neck flasks, PFA, 250 ml, NS 29/32, 1 unit(s)
What is this article?
Single neck flasks, PFA, 250 ml, NS 29/32, 1 unit(s) is the article on this page. Luminix Health distributes Bohlender 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.
