DURAN 258513406 Filter Crucible 50 mL Porosity 4

DURAN 258513406 Filter Crucible 50 mL Porosity 4

The DURAN 258513406 Filter Crucible 50 mL Porosity 4 is engineered for coarse particle filtration where high flow speed and reliable particle retention are required.
It features a sintered-glass filter disk (Porosity 4) that supports rapid liquid drainage while capturing larger solids.

Constructed from borosilicate glass 3.3, the DURAN 258513406 Filter Crucible withstands heat up to ≈ 500 °C, chemical attack, and repeated autoclaving.
Its transparent body makes filtration and drying observation simple and precise.

With a 50 mL capacity, this crucible is suitable for residue collection, solid analysis, and ash determination.
Its robust structure permits direct heating on hot plates or inside furnaces without contamination or deformation.

Reliable and easy to clean, it delivers consistent results in analytical, research, and industrial laboratories.
