Filter Paper Grade
In crucial research areas that impact ever advancing scientific industries, it is vital to be equipped with the right lab tools. Filter papers are critical filtration products, and are used under various conditions for specific samples depending on the type of¬†filter paper grade. These grades define the design, structure, function and application of various filter papers for specific purposes and samples.
Definition of Various Grades of Filter Paper
Various grades are set to filter papers to define the applications for which the papers are meant to be used. Porosity, wet strength, compatibility, capacity, particle retention, flow rate and efficiency are some of the considerations and parameters that go into defining a specific grade for a particular type of filter paper. Volume or surface filtration as well as the raw materials that go into manufacturing filter paper also adds to classification of its grade.
Standard grades for filter papers define how retentive the papers the flow rate, the capacity and density of these papers are. Grade 1 is the initial¬†filter paper grades given to papers that are used for routine applications and that have medium flow and retention rates. Grades go up as high as 602 h, which indicates a filter paper that is very dense and that filters with great precision and takes care of even the minute particles.
Grade definition does not rest solely on the manufacturer of the filter paper. Rather, the set standards in the research industry defines these grades, and it is therefore much simpler to identify a type of filter paper and its application based on the grade set to it
Making a Choice Based On Filter Paper Grade
Your choice of filter paper is made quite simple by considering three factors ‚Äì the sample, your requirement and the filter paper grade. If you wish to check liquids, separate precipitates, monitor pollution based on atmospheric dust, or if you wish to detect gas, you could opt for lower grades of filter paper.
Higher grades of filter paper would come into the picture when you are aiming for higher particle retention, dealing with gelatinous precipitates, sample preparation, determining acidic spectra, HPLC and similar requirements. These papers have higher load capacities and can also handle samples that are generally hard to filter, and that require greater precision in separating particles.
The filter paper grade that you choose can tell you at a glance as to which lab research or study a specific paper should be used for. It also helps in goal planning for your research, as grades define usage of these papers in specific applications and you can plan your tests systematically.
The Importance of Choosing Based On Grades
