Description
Flat-bottom flask 500 ml wide neck borosilicate glass is a medium-length standing flask for laboratory preparation and handling tasks. Fabricated from borosilicate glass 3.3, it offers the chemical resistance and thermal stability expected of standard lab glassware. The wide neck with beaded rim eases charging, stirring and cleaning, while the flat bottom ensures secure standing on benches and hotplates. Nominal volume is 0,5 l; flask diameter is 105 mm, height 170 mm and neck diameter 50 mm. This wide-neck design from manufacturer Witeg is well suited to sample work-up, solution preparation and general wet chemistry where straightforward access to the vessel interior is important. Packs contain 10 pieces, supporting stock replenishment for teaching labs, analytical suites and production-support laboratories. Consistent geometry helps maintain uniform setups across parallel experiments and routine protocols.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, flat bottom, medium length, bor
What is this article?
Flasks, flat bottom, medium length, bor 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.
