FEATURES

Distillation by steam generation.

Automatic «On-line» colorimetric evaluation.

Steam generator withsafety thermostat,over temperatureandoverpressuredevice.

Safety, door closed, that prevents distillation if open.

Detects thatadigestion/distillationtubeispresent.Thisprevents thedosingof NaOH

if there is no tube located.

Universal adapter for MACRO (Ø 42 mm) and MICRO (Ø 26 mm)distillation tubes.

Space saving in the laboratory: the reservoirs for the H2O, NaOH, BoricAcid and

HCl are located inside the unit.

Empties the digestion/distillation tubes and the collector automatically.

REAGENTS

All the reagents used in the «PRO-NITRO A» are easily located:

-Solution of 30-40% NaOH.

-Solution of BoricAcid at 1% concentration ( approx.) with mixed indicators

(Bromo-cresol green and methyl red).

- Reagent for titration: HCl or H2SO4 from 0.05N or 0.25N adjusted to 0.001

Normal.
