Description
Flat-bottom flask with ground glass joints is a laboratory glass vessel with a standard ground joint 29/32 and a nominal capacity of 500 ml, produced in DURAN® glass. The flat base gives a stable footprint on the bench while the precision ground joint supports secure, interchangeable connections to condensers, adapters, stoppers and other standard taper glassware. Offered as 1 pc with a weight of 0,200 kg, this flask from manufacturer Lenz is suited to heating, mixing, reaction and sample-preparation work where a standing flask is preferred to a round-bottom design. DURAN® glass provides the chemical resistance and thermal behaviour expected in routine organic synthesis, analytical chemistry and general laboratory practice. The 29/32 joint size aligns with common European standard taper fittings, enabling modular assembly of distillation, reflux and multi-neck apparatus. It is a practical choice for teaching laboratories, quality-control labs and research groups that need durable flat-bottom reaction flasks with reliable ground-glass connections for everyday wet-chemistry workflows.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Flat-bottom flask w. ground glass joints, 29/32, DURAN®, 500 ml, 1 unit(s)
What is this article?
Flat-bottom flask w. ground glass joints, 29/32, DURAN®, 500 ml, 1 unit(s) is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Matériel de laboratoire.
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.
