FILTER PAPERS - “quantitative”
FILTER PAPERS - “qualitative”
Quantitative papers are recommended for analytical and gravimetric analysis. Manufactured first from high quality 100% cellulose fibres. They are further treated with dilute acid to remove any remaining organic or inorganic impurities. As the last step they are washed and cleaned with demineralised water. They guarantee low ash content around less than 0,01% and around 95% alpha-cellulose amount.
Qualitative papers are recommended for routine separation work. They are manufactured from high quality 100% cellulose fibres for consistent filtration speed, loading capacity and wet strength. They guarantee low ash content around less than 0,1% and around 59% alpha-cellulose amount.

FILTER PAPERS - “general purpose”
FORCEPS - “for filter papers”
Manufactured from high quality 100% cellulose with a good humidity resistance and relatively high absorbtion capacity. Suitable for general laboratory filtrations. Alternatively, can also be used as a bench protector or pharmaceutical product preperation.
Manufactured from high quality, chemical and corrosion resistant AISI 304 grade stainless steel. Most commonly used forceps for placing and picking filter papers during filtering process. Robust and seamless construction guarantees long life cycle.
