Description
Flat-bottom flask with white graduations and beaded rim is a 50 ml laboratory vessel made from heat-resistant, durable borosilicate glass conforming to ISO 1773. The thick wall, heavy base and reinforced rim help reduce the risk of breakage during cleaning and transport. White enamel markings give clear, permanent volume indication for everyday laboratory use. This standing flask from manufacturer ISOLAB Laborgeräte is supplied in packs of 10 pieces and suits general chemistry, sample preparation and teaching applications where a stable flat base is required on the bench. The beaded rim supports secure handling and reliable seating of stoppers or closures during mixing and short-term storage. Borosilicate construction provides the thermal and chemical resistance expected for heating, cooling and solvent contact in analytical and preparative workflows. Graduations printed in white enamel remain legible under standard laboratory lighting and routine cleaning. The flat bottom allows secure placement on hotplates, stirrers and work surfaces without extra supports, making the flask practical for aqueous solutions, organic solvents and media handling in research, quality control and education.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about flask - glass - clear - flat bottom - 50 ml
What is this article?
flask - glass - clear - flat bottom - 50 ml is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Labware.
A flat-bottom flask stands on the bench without a cork ring, which a round-bottom flask will not do. It is for heating on a plate and for simple setups. It is a poorer shape than a round bottom for even boiling under vacuum.
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.
