Description
Pear-shaped flask with standard ground joint NS 29/32 is a laboratory vessel produced from borosilicate glass 3.3 with a nominal volume of 500 ml. It is equipped with a capacity marking, a frosted label area and white inscription, and is supplied without a stopper. The pear-shaped body combined with the interchangeable NS 29/32 socket joint enables reliable connection to condensers, adapters and complementary ground-joint glassware for distillation, evaporation and larger-scale reaction setups. Borosilicate glass 3.3 delivers the thermal and chemical resistance required for everyday laboratory heating and solvent work. The frosted writing zone allows convenient sample labelling while the white volume marking remains legible under normal lab lighting. These flasks from manufacturer Hecht are packed in units of 10 pieces, providing a practical stock quantity for teaching laboratories, research departments and quality-control environments that use standardised joint apparatus. Defined joint size, durable glass and clear markings make the 500 ml pear-shaped flask a dependable choice for routine handling of larger liquid volumes in organic and analytical workflows.

Questions about Flasks, rotary evaporators with ground socket, Boro 3.3, printing white,
What is this article?
Flasks, rotary evaporators with ground socket, Boro 3.3, printing white, is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Flasks (other), inside Beakers & flasks, in Labware.
These are the flasks that are not a plain beaker, Erlenmeyer, round bottom or flat bottom: odd shapes, special necks, flasks defined by a use. The volume and the joint, if there is one, still have to match the setup.
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.
