Carta indicatrice

Pronti per un utilizzo immediato con metodo “immergi e leggi”, i papiri indicatori determinano il contenuto di un campione attraverso semplici confronti di colore con le tabelle fornite. Saturati con una miscela di diversi reagenti, i rilevatori quantitativi ad azione rapida forniscono risposte colorimetriche precise. La nitidezza del colore facilita le valutazioni di routine del tipo “superato/non superato”. Mentre i papiri indicatori universali al tornasole forniscono letture di acidità o alcalinità, i test graduati indicano livelli specifici di elementi. Utilizza questi test compatti in laboratorio o sul campo.
