DURAN 211919105 Filtering Flask 20000 mL

The DURAN 211919105 Filtering Flask is engineered for high-volume filtration in industrial, research, and analytical settings.
Its bottle shape offers excellent stability on the bench and secure handling during operation.
The narrow neck connects tightly to filtration assemblies or rubber stoppers to maintain a strong vacuum seal.

Manufactured from borosilicate glass 3.3, the flask resists extreme temperatures, thermal shock, and chemical corrosion.
A side hose connection enables direct and secure attachment to vacuum lines, allowing smooth and efficient filtrate removal.

With a 20 L capacity, this model supports large-scale reagent purification, solvent recovery, and microbiological media preparation.
The clear glass body lets users observe solution levels and filtration progress with precision and confidence.

The flask autoclaves safely at 121 °C, maintaining sterility and reliability through multiple uses.
The DURAN 211919105 Filtering Flask delivers consistent performance, long service life, and safety in demanding laboratory workflows.
