Description
Allihn filter tube, 30 ml, Por. 3 is a borosilicate 3.3 glass filtration tube fitted with a VitraPOR® sintered filter plate of 20 mm diameter and porosity grade 3. The working height above the filter plate measures 100 mm, providing adequate capacity for reduced-pressure Allihn-style filtrations. Designed for qualitative analysis and preparative chemistry, the tube enables efficient solid–liquid separations under vacuum. The chemically resistant borosilicate 3.3 glass body withstands typical laboratory solvents and thermal stress encountered in routine filtration workflows. Supplied by manufacturer ROBU - Stereon, this Allihn filter tube is intended for laboratories performing preparative work and analytical sample clean-up. The integrated fritted disc of defined porosity ensures reproducible retention characteristics while the cylindrical geometry above the plate accommodates moderate sample volumes. Packaged as a practical multi-piece unit, the filter tubes are ready for immediate use in vacuum filtration assemblies.
