FB70/500 behrotest standing flask is a 500 ml laboratory standing flask equipped with an NS 29 ground joint for secure connection in analytical glassware assemblies. As a Stehkolben-type vessel it offers a stable standing geometry suited to sample preparation, heating, reflux support, and collection steps where a flat, free-standing base is required. The NS 29 joint standardises coupling to condensers, adapters, and related apparatus commonly used in food, environmental, and chemical laboratories. Offered as a single piece under the behrotest range from manufacturer Behr, the FB70/500 provides a defined 500 ml working volume for medium-scale digestions, extractions, and solvent handling. Clear identification by model code FB70/500 simplifies ordering and inventory control when laboratories standardise on NS 29 connections. The flask integrates into existing jointed glassware trains without intermediate adapters when matching NS 29 components are already in use. Its straightforward capacity and joint specification make it a practical building block for routine preparative and analytical workflows that rely on reliable ground-joint sealing and a stable standing form.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about FB70/500 behrotest flat bottom flask 500 ml, NS29
What is this article?
FB70/500 behrotest flat bottom flask 500 ml, NS29 is the article on this page. Luminix Health distributes Behr for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labmateriaal.
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.
