Description
Pointed flask 250 ml NS 24/29 Economy is a laboratory flask featuring a tapered base that promotes thorough drainage and recovery of residual liquids in distillation, concentration and preparative chemistry. Produced from clear borosilicate glass 3.3, it provides solid chemical resistance and thermal stability for standard laboratory heating and cooling steps. The NS 24/29 ground joint allows secure coupling to condensers, distillation heads and complementary jointed apparatus. This Economy model from manufacturer Witeg delivers dependable everyday performance at a practical cost for high-throughput or teaching laboratories. Transparent walls support continuous visual inspection of the contents. Nominal volume is 250 ml with a net weight of 0,114 kg, making the flask suitable for medium-scale organic synthesis, solvent recovery and analytical sample preparation. Supplied as a single piece, it integrates easily into existing glassware sets where borosilicate glass 3.3 reliability and a pointed geometry for complete liquid transfer are required.

Questions about Flask pear shaped 250 ml ST 24/29 Economy
What is this article?
Flask pear shaped 250 ml ST 24/29 Economy 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.
