Description
Receiving flask, 1000 ml, bowl KS 35/25 is a single-neck laboratory vessel fabricated from borosilicate glass 3.3 and equipped with a spherical joint bowl sized KS 35/25. Designed especially for rotary evaporators and related distillation apparatus, it provides a nominal volume of 1 l for efficient collection of larger distillate volumes. With a net weight of 0,288 kg and supplied as 1 pc, the flask combines substantial capacity with manageable handling characteristics for routine laboratory operations. The KS 35/25 spherical joint delivers a reliable seal under vacuum conditions commonly encountered during rotary evaporation. Offered by manufacturer Rettberg, this receiving flask utilises the proven chemical durability and thermal-shock resistance of borosilicate glass 3.3, allowing safe use across a wide temperature range. The single-neck configuration streamlines integration into glassware assemblies, while the bowl joint supports rapid connection and disconnection. Ideal for solvent recovery, concentration steps, and purification sequences, the 1000 ml flask serves organic synthesis, analytical, and process laboratories that require consistent joint standards and robust construction for reproducible, high-throughput work.
This article belongs on Flasks (other), in Beakers & flasks.

Questions about Collecting flask, 1000 ml, spherical joint cup size 35/25
What is this article?
Collecting flask, 1000 ml, spherical joint cup size 35/25 is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Flasks (other), inside Beakers & flasks, in Matériel de laboratoire.
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.
