The fine particle retention of this popular grade is superior for its high retention efficiency at high flow rates and its high loading capacity. Used for determining total suspended solids in water, removal of turbidity, and filtration of bacterial cultures.

Grade AH is used for a wide range of laboratory applications. It is recommended for water pollution monitoring, cell harvesting, liquid scintillation counting, glqss air pollution monitoring. Field of Use : For internal research use only. Products are not intended for diagnostic use or resale. Lot and Batch Numbers can be found pofe a product's label following the words 'Lot' or 'Batch'. More important for COO: enter a "0" if only two numbers are in front of the letter e.

Use up to °C (°F).Brand: Whatman. 13 rows · Different Types of Qualitative Whatman Filter Paper & their Properties The most common .

Filter paper. We all use it at one time or another. Is it just because your protocol tells you to? Qualitative filter papers are what most users would consider general purpose filter papers. There are a vast range of applications in and out of the laboratory.

Composed of cellulose fiber, these filters are manufactured from high-quality cotton linters treated to maximize alpha cellulose. Alpha cellulose is the most stable form of cellulose, with the highest degree of polymerization.

Cellulose paper made from a high percentage of alpha cellulose, such as Whatman paper, is a sign of high quality and consistency. Qualitative filter paper grades are based on various properties including particle retention, thickness, and weight.

Unlike quantitative filter papers, of which ashless grades can be burned off for analytical applications, qualitative papers are more suited for general purpose use.

The most common qualitative paper grades are , , , , and , which have applications across multiple industries. Below are summaries of the grade properties and common uses.

Hopefully, this summary of properties and applications of these popular qualitative filter papers clarifies why you might be using one or more of these paper grades in your work.

Edit Profile. Specific applications include: Qualitative analytical separation for lead sulfate, calcium oxalate, and calcium carbonate Soil analysis and seed testing Separating foodstuffs from associated liquid or extracting liquid Collecting atmospheric dust for photometric measurement Gas detection through the addition of a chromogenic reagent Filter Paper Grade 2 Circles: Specific applications include: Air pollution monitoring where the collection of fine particles is not critical Routine clean-up of biological fluids or organic extracts Filter Paper Grade 5 Circles: 25 mm to mm available prepleated Particle retention 1 : 2.

Specific applications include: Retaining fine precipitates in chemical analysis Clarifying cloudy suspensions in soil and water analysis Filter Paper Grade 6 Circles: It has high absorbency and increased wet strength, and is often specified for boiler water analysis. Offers high absorbency and increased wet strength. Related Documents:. Related Products:. Whatman Filter Selector Lab filtration glossary.

Filter Paper Grade 1. Circles: 10 mm to cm available prepleated Sheets: 26 x 31 mm to x mm. Grade 1 is the most widely used filter paper in routine applications requiring medium retention and flow rate, and is most frequently used for clarifying liquids.

Specific applications include: Qualitative analytical separation for lead sulfate, calcium oxalate, and calcium carbonate Soil analysis and seed testing Separating foodstuffs from associated liquid or extracting liquid Collecting atmospheric dust for photometric measurement Gas detection through the addition of a chromogenic reagent.

Filter Paper Grade 2. Circles: Grade 2 is slightly more retentive than Grade 1, with an equivalent increase in filtration time. Specific applications include: Plant growth trials, where the extra absorbency is utilized to hold soil nutrient Contaminant monitoring in air and soil.

Filter Paper Grade 3. Circles: 23 mm to mm available prepleated Sheets: 26 x 31 mm to x mm. Grade 3 is double the thickness of Grade 1, so it can hold more precipitate without clogging and has increased wet strength.

Filter Paper Grade 4. Circles: 27 mm to mm available prepleated Sheets: 38 x mm to x mm. Grade 4 is a fast filter material that is well suited for retention of coarse particles and gelatinous precipitates, such as ferric hydroxide and aluminum hydroxide. Specific applications include: Air pollution monitoring where the collection of fine particles is not critical Routine clean-up of biological fluids or organic extracts.

Filter Paper Grade 5. Particle retention 1 : 2. Grade 5 provides the maximum degree of fine particle retention in the qualitative paper range, with an equivalent slow flow rate.

Specific applications include: Retaining fine precipitates in chemical analysis Clarifying cloudy suspensions in soil and water analysis.

Filter Paper Grade 6. Thick with a high loading capacity, Grade 6 provides similar particle retention to Grade 5 with twice the flow rate. Plant growth trials, where the extra absorbency is utilized to hold soil nutrient Contaminant monitoring in air and soil. Filter Paper Grade A thick filter paper with very high loading capacity for fast filtration of medium to coarse precipitates. Circles: mm to mm available prepleated Sheet: x mm.

Popular thin filter papers, Grade provides medium-fast flow rate and fine particle retention. A medium-fast flow rate paper with medium-to-fine particle retention, Grade is used in a variety of routine analytical applications, including: Determination of fat content in food testing Removal of carbon dioxide and turbidity from beer and other beverages. Filter Paper Grade L.

A qualitative filter paper with low fat content. A medium-fast to fast flow rate paper with medium particle retention, Grade has a high thickness, giving it a high loading capacity.

Filter Paper Grade h. Grade h is a dense filter designed for collecting very fine particles.
