Qualitative filter paper

The filter papers for qualitative analysis FILTER-LAB ® are specially manufactured to achieve separation and identification of substances known characteristics and to perform a great number of leaks in routine analysis.

The range consists of two perfectly distinct families according to the requirements of the test or the purpose of filtration:

1318

A filter paper for qualitative analysis with the rough surface. This is achieved between 10 and 20% more surface area, providing two features added to the filter:

* Increased stiffness in the filtration process

* Excellent load capacity

Recommended in leaks and clarifications of production processes or dirty or thick liquids for cleaning difficult samples.

Quantitative filter paper

The filter paper for quantitative analysis FILTER-LAB® are manufactured using cellulose fibers and cotton linter high purity, which contain alpha-cellulose is practically 100%. These filter papers require a special production process.

Once manufactured the filter paper in the desired physical conditions (weight, thickness, filtration rate, etc.) began a process of washing with acids (usually HF and HCl) which concludes with a final cleaning with demineralized water. This will achieve two important characteristics:

* High resistance to wet state.
* Ash content less than 0.01%
