Adsorber Tube 6.1403.030 for Karl Fischer Titration
The Metrohm model 6.1403.030 is an adsorbent tube specifically designed for Karl Fischer titration analyses, used in particular with devices such as the 917 Coulometer. In a medical context, where precise measurement of moisture content is crucial – for example, for pharmaceutical products, biological samples or sensitive solvents – the effectiveness of this tube contributes significantly to the reliability of results.
The tube is filled with molecular sieves (6.2811.000), which absorb residual moisture from the circulating air, preventing any alteration of the reagents used in the titration cell. During installation, a small cotton pad is placed at the bottom, then the tube is filled three-quarters full with molecular sieves, covered with a second pad, and sealed. This assembly protocol ensures optimal use of the adsorber tube, guaranteeing a clean, dry air flow, which is essential for the quality of coulometric measurements.
In the titration cell, the 6.1403.030 adsorbent tube is usually inserted into the generating electrode. It actively contributes to the stability of the system by reducing the base drift caused by humidity. This rigorous control of the environment is essential in hospital, clinical and biomedical research laboratories, where analysis standards are strict and margins of error are minimal.
It is recommended that the molecular sieve be replaced regularly to maintain optimal efficiency, with each refill dateable directly on the tube for traceability purposes. This best practice contributes to rigorous quality control, as required in medical protocols.
