Description
Evaporating flask 100 ml NS 19/26 flat bottom is a pear-shaped borosilicate glass vessel intended for rotary evaporation and laboratory concentration tasks. Made from clear borosilicate glass 3.3, the flask offers the chemical durability and thermal performance expected in everyday solvent-removal workflows. Nominal capacity is 100 ml (0,1 l) with a standardised NS 19/26 ground joint for direct connection to common evaporator assemblies and adapters. The flat bottom allows the flask to stand securely on the laboratory bench between runs. Supplied as clear glass from manufacturer Witeg, the design permits straightforward visual monitoring of the evaporating liquid. Typical uses include concentration of organic extracts, solvent exchange, and preparation of samples for further analysis in research, quality-control and process-development laboratories. The 100 ml volume balances working capacity with manageable size for medium-scale batches. Pack size is 10 pieces, facilitating efficient restocking of shared laboratory glassware inventories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Evaporating flask 100 ml ST 19/26 flat bottom
What is this article?
Evaporating flask 100 ml ST 19/26 flat bottom is the article on this page. Luminix Health distributes Witeg 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.
