Description
Triple neck flask, PFA, 250 ml provides three ground-joint ports for complex laboratory setups, with main and side necks specified as NS 29/32. The 250 ml capacity balances workable reaction volume with multi-port access for simultaneous addition, reflux, sampling, or gas control. Built from PFA, the flask sits within the round-flask and ground-joint labware category used in synthesis, distillation, and general wet chemistry. Uniform NS 29/32 joint sizing on the necks simplifies selection of stoppers, condensers, and adapters from standard inventories. Each flask is delivered as a single unit weighing approximately 0,120 kg, supporting clear packing and handling. From manufacturer Bohlender, this triple-neck PFA design serves research, development, and routine laboratory environments that need more than two connection points on a mid-size vessel. Explicit capacity and joint data enable consistent apparatus design and method documentation across users and sites.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Triple neck flasks, PFA, 250 ml, NS 29/32, side neck NS 29/32, 1 unit(s)
What is this article?
Triple neck flasks, PFA, 250 ml, NS 29/32, side neck 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.
