DURAN 211917301 Filtering Flask 5000 mL

The DURAN 211917301 Filtering Flask provides efficient filtration for laboratories requiring high-capacity performance.
Its bottle shape improves stability on the bench and minimizes tipping during use.
The narrow neck fits standard filter assemblies or rubber stoppers, ensuring a secure seal under vacuum pressure.

Made from borosilicate glass 3.3, this flask endures thermal shock, corrosive chemicals, and repeated sterilization without loss of strength.
A side hose connection allows quick and tight attachment to vacuum systems, guaranteeing steady and controlled filtrate removal.

The 5 L capacity makes it ideal for reagent purification, bulk solvent recovery, and microbiological sample clarification.
The transparent glass surface allows users to monitor liquid levels and filtration progress precisely.

The flask autoclaves safely at 121 °C, maintaining sterility and enabling reliable reuse.
Built for durability and performance, the DURAN 211917301 Filtering Flask delivers consistent results across industrial, academic, and chemical applications.
