Description
Round flasks in DURAN® transparent glass with a 1000 ml capacity and NS 45/40 ground joint are laboratory round-bottom vessels designed for distillation, Soxhlet work and sample preparation. Transparent DURAN® glass allows clear monitoring of larger liquid volumes during heating, reflux, extraction or concentration steps. The NS 45/40 ground joint offers a wide, standardised interface to matching condensers, adapters and other laboratory glassware components used in environmental analysis and preparative setups. Each flask is supplied as 1 pc and has a weight of 0,310 kg, providing a practical single-unit pack for litre-scale laboratory tasks. These round flasks from manufacturer Lenz fit distillation and Soxhlet appliances as well as sampling and sample-preparation workflows. The 1000 ml working volume accommodates larger batch sizes while the round form supports even heat distribution with appropriate heating equipment. Suitable for research and routine laboratories that specify DURAN® transparent round flasks with NS 45/40 joints for distillation trains and related preparative applications.

Questions about Round flasks,DURAN®, transparent glass, 1000 ml, NS 45/40, 1 unit(s)
What is this article?
Round flasks,DURAN®, transparent glass, 1000 ml, NS 45/40, 1 unit(s) is the article on this page. Luminix Health distributes Lenz 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.
