Cytiva Carte per analisi quantitativa
Per un'analisi accurata in applicazioni sensibili a bassissimi livelli di contaminazione di fondo e in analisi gravimetriche. La carta da filtro quantitativa Whatman™ Grado 40 è utile nelle applicazioni in cui il contenuto di ceneri potrebbe influire sulle misurazioni del peso dei campioni combusti.
Marca: Cytiva 1440-047
Dettagli aggiuntivi : Peso : 0.02000kg
Descrizione
Supports accurate analysis in applications sensitive to very low levels of background contamination. Whatman™ Quantitative Filter Paper: Grade 40 Circles are additionally useful in gravimetric analysis where ash content might affect weight measurements of combusted samples.
Ashless grades are very pure filters suitable for a wide range of critical analytical filtration procedures. Whatman™ quantitative filter papers are designed for gravimetric analysis and the preparation of samples for instrumental analysis.- High-purity filters for quantitative analysis
- Contain 0.007% maximum ash content
