Description
The round bottom flask with stopcock is a 10 ml laboratory flask made of borosilicate glass 3.3 for small-scale liquid handling and reaction work. This single-unit vessel combines a round-bottom geometry with an integrated stopcock for controlled addition, sampling, or drainage of contents during laboratory procedures. Offered as 1 pc and weighing 1,045 kg, the flask suits compact setups in synthetic, analytical, and teaching laboratories where modest volumes are processed. Borosilicate glass 3.3 is specified as the construction material, aligning the item with common heat- and chemically resistant laboratory glassware families. From manufacturer Winzer, the 10 ml round bottom flask with stopcock fits workflows that rely on round flasks and related jointed or valved glass components. Clear capacity and material designation support selection against other round flasks used for heating, mixing, or temporary storage of liquids. Laboratories organising multi-size glassware inventories can add this small-volume option for trials, aliquots, and preparatory steps. Stated details include volume, material, stopcock configuration, unit quantity, and weight for straightforward product identification.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask with stopcock, 10 ml, borosilicate glass 3.3, 1 unit(s)
What is this article?
Round bottom flask with stopcock, 10 ml, borosilicate glass 3.3, 1 unit(s) is the article on this page. Luminix Health distributes Winzer 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.
