        Carta da Filtro Qualitativa Ashless

        Le Carte da filtro GVS raggiungono gli standard per la filtrazione in laboratorio.

        Utilizzando materiale di più alta qualità, le carte da filtro GVS hanno una resistenza meccanica, un livello di qualità e un'affidabilità migliori.

        Utilizzate per analisi qualitative, la carta da filtro qualitativa è realizzata con polpa raffinata e linters di puro cotone con un contenuto al 100% di alfa-cellulosa che le conferisce una serie di diverse proprietà di filtrazione.

        Il contenuto di ceneri inferiore allo 0,06% non viene ridotto dal post-trattamento.

        Proprietà

        GVS fornisce un’ampia gamma di soluzioni per tutte le applicazioni:

        GRADO 01 – Filtrazione media

        La carta da filtro più utilizzata. Ritenzione e portata media. Questo grado copre un'ampia gamma di applicazioni di laboratorio ed è spesso utilizzata per la chiarificazione di liquidi. Tradizionalmente questo grado viene utilizzato nelle separazioni analitiche qualitative per applicazioni di laboratorio di routine, nonché nella filtrazione rapida di precipitati fini come solfato di piombo, ossalato di calcio (caldo) e carbonato di calcio. In agricoltura, viene utilizzato per l'analisi del suolo e le procedure di analisi delle sementi. Nell'industria alimentare, il GRADO 01 viene utilizzato per numerose tecniche di routine per separare gli alimenti solidi dal liquido associato o dal liquido di estrazione.

        GRADO 02 –  Filtrazione media-lenta

        Leggermente più ritentivo e assorbente del GRADO 01 e quindi con una velocità di filtrazione da moderata a lenta. Oltre alla filtrazione generale, il GRADO 02 viene utilizzato per il monitoraggio di contaminanti specifici nell'atmosfera, la filtrazione di precipitati fini, l'analisi del suolo; viene spesso utilizzato come filtro ripiegato in un imbuto analitico.

        GRADO 03- Filtrazione media-lenta (thick)

        Velocità di filtrazione da media a bassa con il doppio dello spessore rispetto al GRADO 01. Ritenzione di particelle fini ed eccellente capacità di carico. Lo spessore extra conferisce una maggiore resistenza e consente un maggiore carico di soluto. Utilizzato preferibilmente per liquidi difficilmente chiarificabili, essenze, oli, tinture, particolarmente utili per l'impiego in imbuti Büchner.

        GRADO 04- Filtrazione molto veloce

        Elevatissima velocità di filtrazione con ottima ritenzione di precipitati grossolani come idrossidi e solfuri metallici o sostanze gelatinose. Preferibilmente utilizzato come filtro rapido per vari precipitati di metalli organici, pulizia di routine di fluidi biologici, analisi dell'industria alimentare, monitoraggio dell'inquinamento atmosferico (tassi elevati e la raccolta di particelle fini non è critica).

        GRADO 05- Filtrazione molto lenta

        Tasso di filtrazione più basso e grado massimo di filtrazione o ritenzione di particelle fini. Preferibilmente utilizzato come filtro chiarificante per sospensioni torbide e analisi dell'acqua e del suolo. Particolarmente utilizzato in condizioni di filtrazione difficili e precipitati a grana extra fine come solfato di bario, ossido rameoso, spesso indicati per la chiarifica del vino.
