Description
HCl absorber according to DIN 38409 with NS 29/32 joint is a specialised borosilicate 3.3 glass apparatus for oxygen-demand determinations in water analysis. It incorporates a VitraPOR® filter candle measuring Ø 25 mm × 65 mm height with porosity 1, giving a total apparatus length of 190 mm. The unit is employed in procedures where 1 mol K2Cr2O7 corresponds to 1,5 mol O2, enabling accurate assessment of oxidisable matter. Manufactured by ROBU - Stereon, the absorber integrates seamlessly into standard laboratory glassware trains via the NS 29/32 connection. Its chemically resistant borosilicate construction withstands typical acidic and oxidative conditions encountered in COD-related work. Compact dimensions facilitate handling inside fume hoods while the defined porosity ensures consistent gas–liquid contact. Suitable for water-quality laboratories performing standardised oxygen-demand measurements that require a dedicated HCl absorption stage.

Questions about HCL Absorber, DIN 38409 ST 29/32, Por. 1, Ht 190 mm
What is this article?
HCL Absorber, DIN 38409 ST 29/32, Por. 1, Ht 190 mm is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
