Description
FB70/250 behrotest® standing flask 250 ml NS 29 is a laboratory standing flask with a standard ground joint NS 29 and a fourfold heating contact surface for energy-saving operation. The 250 ml nominal volume supports heating, digestion and related thermal work where efficient heat transfer into the flask contents is required. The fourfold heating contact area is intended to improve energy efficiency during temperature-controlled laboratory procedures. Supplied as 1 pc, the FB70/250 belongs to the behrotest range from manufacturer Behr and is classified among standing flasks for general laboratory use. The NS 29 joint allows connection to matching condensers, adapters and other ground-joint glassware in modular assemblies. Laboratories performing evaporations, digestions or heated sample preparation can use this standing flask wherever a 250 ml capacity and multi-point heating contact are needed. Clear designation as FB70/250 aids ordering and inventory control. Country of origin is Germany. This behrotest® standing flask combines defined volume, NS 29 connectivity and an energy-oriented heating contact design for everyday heated laboratory applications.

Questions about FB70/250 behrotest round bottom flask 250 ml with neck NS 29
What is this article?
FB70/250 behrotest round bottom flask 250 ml with neck NS 29 is the article on this page. Luminix Health distributes Behr 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.
