Description
Special flask 3000 ml with socket NS 29/32 is a pear-shaped laboratory vessel specifically intended for drying powdered substances. Fabricated from durable borosilicate glass 3.3, the flask features a centered design that supports even heat distribution and efficient handling during drying procedures. With a nominal volume of 3 l, it integrates seamlessly into standard laboratory setups requiring NS 29/32 ground joints. This specialized form, supplied by manufacturer Rettberg, belongs to the category of pear and evaporator flasks and proves particularly useful when processing fine powders that demand controlled drying conditions. The robust glass construction resists thermal shock while maintaining chemical inertness, making the vessel suitable for routine sample preparation, solvent removal support, or preparatory drying steps ahead of further analysis. Net weight is 0,520 kg, and the unit is offered as a single piece, ready for immediate incorporation into existing glassware assemblies. Its pear geometry facilitates powder containment and easy transfer, enhancing workflow reliability in research and quality-control environments focused on solid-sample handling.

Questions about Special flask, 3000 ml, socket size 29/32, for drying powdery
What is this article?
Special flask, 3000 ml, socket size 29/32, for drying powdery is the article on this page. Luminix Health distributes Rettberg 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.
