Quantitative Filter Paper

 

  • Quantitative filter paper is used for precise quantitative analysis to detect kinds and amounts of materials in analysis samples.

 

Features Of Product

 

 

Hyundai Micro’s quantitative filter paper is made of refined pulp with nearly 100% alpha-cellulose and has less than 0.1% of ash contents. As quantitative analysis requires high purity, it is washed with acid. This can be produced in any size that you need as well as in standard sizes.
We maintain the highest quality in accordance with ISO 9001:2008 to guarantee reliable results.

suitable for filtration of medium-sized
precipitate such as calcium oxalate, magnesium /
ammonium phosphate

  • Thin filter speed with fast filtration speed
  • Used for filtration of fine particles such as barium

sulfate, metastannic acid and cuprous oxide

FEATURES
  • Filtration of medium-sized precipitate such as

calcium oxalate, magnesium phosphate,
ammonium phosphate, potassium carbonate,
zinc sulfide and stannic oxide

  • Filtration of pharmaceutical, zoological,

and botanical experiments

  • Analysis of a very small amount of precious metal
  • Beverage analysis
  • Chemical and medical experiments
APPLICATION

 

 

  • The pore sizes are indicated in accordance with the test methods selected by each filter paper manufacturer.
    Thus, filtration performance may be the same even though pore sizes are different from those of others manufacturers.

  • Basic weight ( g / ㎡ ) : In accordance with DIN EN ISO 536, a test is performed with filter papers from 500㎠ to 1,000㎠
  • Thickness ( mm ) : In accordance with DIN EN ISO 534, the value measured with a thickness measurer under pressure
    of 10N / ㎠
  • Filtration speed (s / 10ml ) : Fold a filter paper with a diameter of 110m in quarter and soak it.
    Then, hang it and filter 10 ml of distilled water at 20 °C. Time that it takes for filtration is measured.
  • Retention rate ( ㎛ ) : Retention rate is calculated by test methods of filter paper manufactures. As each manufacturer has a
    different test method, use these data for reference only.
  • Ash Contents ( % ) : Weight of residues after 10g of filter paper is ignited in platinum crucible at 800℃.
