Grade 301 is the slowest of the qualitative papers. This grade is used in qualitative analytical techniques to determine and identify materials. It is also extremely efficient in retaining very fine particles. Grade 301 is generally used for biological products, water analysis, soil analysis and fine precipitates such as cold precipitated barium sulfate. Grade 301 is additionally utilized with Buchner funnels and to clarify cloudy suspensions and wine. -
Grade 302 is a thick smooth paper, suitable for the removal of fine particles. This paper is made with 100% pure cellulose fibres that have been strengthened to resist the pressure when they are used in filter press systems. There is therefore no contamination danger during transfer steps. This high absorbency grade is twice as thick as Grade 301 with a bigger pore size. The extra thickness gives higher wet strength and loading capacity, enabling more precipitate to be held without clogging the filters and better handling. Grade 302 is also highly suitable for use in Buchner funnels and dye filtration.
-
This grade has a larger pore size than Grade 301, but with a lower filtration speed. Grade 303 also has higher absorption than Grade 301 is it used in general laboratory applications. Grade 303 is also found in agricultural and environmental laboratories for plant growth trials, soil testing and air analysis for monitoring specific contaminants and in the filtration of organic and sulfide precipitates.
-
This grade covers a wide range of laboratory applications and is used for clarifying liquids and for rapid filtration of coarser precipitates such as lead sulfate, lead chromate, calcium oxalate, calcium carbonate, aluminum phosphate, barium carbonate and beryllium hydroxide. Grade 304 can be found in soil analysis, seed testing and in air pollution to collect dust-laden air and is also commonly used in the food industry to separate foodstuffs from the associated liquid of extracting liquid.
-
This grade is used for the filtration of coarse particles and gelatinous precipitates such as ferric aluminum and magnesium hydroxides. Grade 305 is used in air monitoring and gas filtration when high flow rate is needed. This grade is also found in routine cleanup analysis of insoluble liquids such as biological fluids and organic elements.

Manufactured from high-quality polystyrene which resists to most acids, bases and many commonly used solvents. Guarantees temperature resistance between -10°C to +70°C. Sterile spatulas are manufactured as single use. They eliminate the cost of separate sterile bags or containers in sample collection. Perfect shape and size enable efficient sampling of various powder, granulate and paste form samples. Sharp blade penetrates directly into paper or plastic bags for optimum and quick sampling process. Easy to grip and long handle increases the distance between the hand and the sample to reduce cross-contamination risks. Approximate volume values are printed on scoop handles. Sterile spatulas are featured with a transparent lid which protects the samples from dust, moisture, and other effects. The transparent lid should be closed immediately after the sampling to secure a sterile and contamination-free sample. The lid is featured with a frosted write on area for practical use. -
