Advantec filter papers have a wide range of applications. Ideal for qualitative filtration analysis: they retain particles of 1-6 microns in horizontal and vertical flow. Used in many industries.
- 100% cotton linters cellulose.
- PH resistant: 0 to 12
- Heat resistance: up to 120 ° C
- Wide selection - seven types
- Ash content: 0.1%.
Advantec filter papers are renowned for their quality, strength, versatility, durability and cost effectiveness. The company produces 7 types of filter papers, differing in strength, thickness, retention and flow capacity and appearance (corrugated and smooth).
They are used for cleaning and removing sediment and preparing for qualitative analysis.
Each type of filter paper for qualitative analysis has its own characteristics, you can familiarize yourself with them below, and select the type for your application:
№ 1 - Retains large crystalline particles and gelatinous precipitates. Fast flow rate, smooth surface, normal hardness
№ 2 - Retains medium crystalline precipitates, fast flow rate, smooth surface, normal hardness
№ 231 - Retains crystalline precipitates, moderate flow rate, smooth surface, normal hardness
№ 232 - Retains medium to medium- fine particulates, slow flow rate, smooth, normal hardness
№ 131 - High retention efficiency for fine crystalline precipitates like barium sulfate, slow flow rate, smooth surface, normal hardness
№ 235 - Highest retention efficiency, retains very fine particulates, very slow flow rate, smooth
№ 101 - Retains large particles

*1 - flow time is the time in seconds required to filter 100 ml of distilled water at 20 ° C under pressure supplied by a 10 cm water column through a 10 cm2 section of filter paper.
*2 - absorption rate is the distance in cm that water travels in a vertical strip of filter paper in ten minutes at 20 ° C.
*3 - wet strength is the compressive strength measured with the Mullen Burst Strength Tester after soaking the filter paper in water.
- The following diameters (mm) are available: 55, 70, 90, 110, 125, 150, 185, 240, 285, 300, 330, 360, 400, 500, 600 (additional sizes available on request).
