Description
neoChoice qualitative fluted filters, grade 3hw, are laboratory round filters intended for examining pollutants, plant-available nutrients and trace elements in soil samples. Each filter measures 185 mm in diameter and is supplied in a pack of 100 pieces for continuous laboratory use. Grade 3hw is specified with a basis weight of 65 g/m², a filtration speed of 20 s/10 ml and a Herzberg value of 140 s/100 ml, supporting reliable general filtration performance. The pre-pleated design increases the effective filtration area in standard funnels and promotes even flow when processing soil extracts and related aqueous suspensions. These properties make the filters suitable for routine environmental and agricultural sample preparation where qualitative clarification is required before further analysis. Offered by manufacturer neolab - Labor within the neoChoice line, the papers are aimed at general filtration rather than quantitative ash-free work. The 185 mm format balances capacity and handling convenience for medium-volume soil and nutrient extraction workflows in research and routine testing laboratories.

Questions about neoChoice pleated filters, qualitative, 3hw, 185 mm Ø, 100 pieces/pack
What is this article?
neoChoice pleated filters, qualitative, 3hw, 185 mm Ø, 100 pieces/pack is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Filter paper, inside Filtration, in Lab consumables.
Filter paper is a cellulose sheet of a stated retention and speed. Qualitative paper clarifies. Quantitative, ashless paper is for a precipitate that will be weighed or ashed, because the paper itself leaves almost no ash. The diameter has to match the funnel.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
