Flask
The chemistry flasks offered by AllChimie are the reference vessels for heating, reflux, distillation and synthesis operations. Manufactured from borosilicate glass 3.3, they provide high thermal resistance, excellent chemical inertness and dimensional stability suited to demanding experimental conditions.
Depending on geometry — round-bottom, flat-bottom, single, double or triple neck — these flasks integrate into heating mantle setups, magnetic stirrers, distillation columns and vacuum lines. Standardised ground-glass joint versions (NS 14/23, NS 19/26, NS 24/29, NS 29/32) guarantee tight connections with condensers, dropping funnels and other glassware components.
The range covers volumes from a few millilitres to several litres, for applications in research, quality control, chemical, cosmetic and food industries. Some models comply with ISO or DIN standards and are autoclavable as required by analytical needs.
In a synthesis setup, the flask is mounted on a laboratory support and paired with a dropping funnel for controlled addition, a stirrer for homogenisation, and silicone stoppers for sealing auxiliary ports. At the end of the reaction, the product is transferred to an Erlenmeyer flask or storage bottle.
