Traditionally, this grade is used in qualitative analytical separations for precipitates such as lead sulfate, calcium oxalate (hot), and calcium carbonate. In agriculture, it is used for soil analysis and seed testing procedures. It is also used for numerous routine techniques in the food industry to separate solid foodstuffs from associated liquid or extracting liquid; and is widely used in education for teaching simple qualitative analytical separations. In air pollution monitoring, using circles or rolls, atmospheric dust is collected from airflow and the stain-intensity is measured photometrically. For gas detection, the paper is impregnated with a chromogenic reagent and color formation is quantified by optical reflectance. Retention: 11µm. Diameter: 5.5cm. 100/Pack. Whatman #: 1001-055. ## Features - 5.5cm - Grade 1 - Covers a wide range of laboratory applications; frequently used for clarifying liquids - Areas of use include the food industry, agriculture, air pollution monitoring, and gas detection - Widely used in education for teaching simple qualitative analytical separations ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00394F97S | | Batteries Included | No | | Batteries Required | No | | Best Sellers Rank | 87,304 in Business, Industry & Science (See Top 100 in Business, Industry & Science) 25 in Quantitative Filter Paper | | Customer Reviews | 3.7 3.7 out of 5 stars (18) 3.7 out of 5 stars | | Cutting Diameter | 55 Millimetres | | Date First Available | 1 Nov. 2012 | | Guaranteed Software Updates Until | unknown | | Item Diameter | 55 Millimetres | | Item Model Number | F1000-2 | | Item Package Quantity | 1 | | Item Thickness | 180 Millimetres | | Item Weight | 227 g | | Manufacturer | GE Healthcare | | Material | PE_(Polyethylene), Paper | | Part Number | 1001-055 | | Size | 5.5cm | ## Images ![Whatman 1001-055 Quantitative Filter Paper Circles, 11 Micron, 10.5 s/100mL/sq inch Flow Rate, Grade 1, 55mm Diameter (Pack of 100) - Image 1](https://m.media-amazon.com/images/I/51S8IEqyTLL.jpg) ## Available Options This product comes in different **Size Name** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by on Reviewed in the United Kingdom 13 May 2022* Nice thick filter papers, fit a 58mm portafilter and can be reused a couple of times.
