Product Description

Kualitatif Filter Paper dari Whatman adalah kertas yang biasa digunakan untuk penyaringan secara umum.

Penggunaannya sangat luas baik di dalam maupun di luar laboratorium.

Filter Paper atau kertas saring ini terdiri dari serat selulosa (Cellulose fiber) yang memang diproduksi dari bahan berkualitas untuk memaksimalkan alpha cellulose.

Alpha cellulose adalah selulosa yang paling stabil dengan polymerisasi tingkat tinggi, kertas selulosa ini dibuat dengan persentas tertinggi dari Alpha Selulosa seperti Whatman yang menggunakan teknologi tersebut.

Product Variants

Grade atau tingkatan filter paper itu terkait dengan ketahanan, ketebalan dan berat.

Berikut penjelasan lengkapnya :

Paper Grade Available Sizes Properties Applications
Filter Paper Grade 1
  • Circles: 10 mm to 150 cm (available prepleated)
  • Sheets: 26 x 31 mm to 600 x 600 mm
  • Particle retention1: 11µm
  • Nominal thickness: 180 µm
  • Nominal basis weight: 87 g/m2
  • Nominal ash content2: 0.06%
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: 42.5 mm to 500 mm (available prepleated)
  • Sheets: 460 x 570 mm to 580 x 680 mm
  • Particle retention1: 8µm
  • Nominal thickness: 190 µm
  • Nominal basis weight: 97 g/m2
  • Nominal ash content2: 0.06%
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 320 mm (available prepleated)
  • Sheets: 26 x 31 mm to 600 x 600 mm
  • Particle retention1: 6µm
  • Nominal thickness: 390 µm
  • Nominal basis weight: 185 g/m2
  • Nominal ash content2: 0.06%
Grade 3 is double the thickness of Grade 1, so it can hold more precipitate without clogging and has increased wet strength. It is designed for use in Büchner funnels, and the high absorbency makes Grade 3 well suited for sample transport after collection.
Filter Paper Grade 4
  • Circles: 27 mm to 400 mm (available prepleated)
  • Sheets: 38 x 114 mm to 580 x 580 mm
  • Particle retention1: 25µm
  • Nominal thickness: 210 µm
  • Nominal basis weight: 92 g/m2
  • Nominal ash content2: 0.06%
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
  • Circles: 25 mm to 320 mm (available prepleated)
  • Particle retention1: 2.5µm
  • Nominal thickness: 200 µm
  • Nominal basis weight: 100 g/m2
  • Nominal ash content2: 0.06%
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
  • Circles: 42.5 mm to 240 mm (available prepleated)
  • Particle retention1: 3µm
  • Nominal thickness: 180 µm
  • Nominal basis weight: 100 g/m2
  • Nominal ash content2: 0.06%
Thick with a high loading capacity, Grade 6 provides similar particle retention to Grade 5 with twice the flow rate. It has high absorbency and increased wet strength, and is often specified for boiler water analysis.

  • Plant growth trials, where the extra absorbency is utilized to hold soil nutrient
  • Contaminant monitoring in air and soil
Filter Paper Grade 591
  • Sheet: 580 x 580mm
  • Particle retention1: 12µm
  • Typical thickness: 180 µm
  • Basis weight: 161 g/m2
  • Nominal ash content2: 0.06%
A thick filter paper with very high loading capacity for fast filtration of medium to coarse precipitates. Offers high absorbency and increased wet strength. Also available prepleated as Grade 591 ½.
Filter Paper Grade 595
  • Circles: 110 mm to 150 mm (available prepleated)
  • Sheet: 580 x 580mm
  • Particle retention1: 7µm
  • Typical thickness: 180 µm
  • Basis weight: 68 g/m2
  • Alpha cellulose: 98% minimum
Popular thin filter papers, Grade 595 provides medium-fast flow rate and fine particle retention. It is used in a variety of routine analytical applications, including:

  • Particle separation from food extracts
  • Filtration of solids from digested environmental samples for iCP/AAs analysis
