Cellulose fibers and very pure cotton fibers have been used to make it.
Alpha cellulose content is almost 100%. However, cellulose fibers in their natural state contain small amounts of organic and inorganic impurities. This is the reason why these filter papers require a special production process.
When the filter paper is produced in optimal physical conditions (weight in grams, thickness, filtration speed, etc.), the acid washing process begins. (generally (HF and HCl) which ends with a final cleaning with demineralized water. We obtain two important properties in this process: high resistance to the wet state and an ash content of less than 0.01%. All these, these filters are particularly suitable for filtration with Buchner funnels in quantitative analysis because they meet the requirements.
