Categorii:

Filtrare foarte rapida » Filtre grupa 1235: Hartie de filtru cu pori mari pentru precipitate voluminoase precum aluminiu, AL(OH)3, hidroxid de crom, Cr(OH)3, fier Fe(OH)3, sau precipitate geletinoase, analiza gravitationala de particule suspendate in aer, etc.

Filtrare rapida » Filtre grupa 1238 : Filtrare rapida dar cu eficienta mai mare in retentie particulelor, este cel mai des folosita pentru precipitate voluminoase precum fierul si sulfura de argint; carbonati alcalini; cromat de plumb, arsenic, cadmiu, alimente, etc.

Filtrare medie » Filtre grupa 1240: Hartie de filtru de uz general cu pori medii pentru precipitate medii sau particule cu dimensiuni medie precum fosfat de amoniu-magneziu, oxalat de calciu, arsenat amoniu-magneziu, sulfat de bariu, folosita in industria cementului conform UNE 80-112; EN-196-6 (test Blaine), calculare magneziu in apa si in analiza produse alimentare si probe de sol, etc.

Filtrare mediu lent » Filtre grupa 1242: Hartie de filtru foarte pura cu pori mici utilizata in analize gravitationale, de cement si materiale de constructi, pentru extractie de apa din sol, determinarea conttinutul de ulei in apa, sedimente in lapte, la precipitate fine precum radionuclide si particule din atmosfera, dioxidul de fier, fluorura de calciu, sulfat de nichel, sulfat de zinc, dioxid si molibdat de fier

Filtrare lenta » Filtre grupa 1244: Hartie de filtru cu pori foarte mici utilizata la filtrari dificile precum filtrarea particule semicoloidale, sulfatului de bariu, oxid de cupru in general este folosit pentru analiza particule insolubile in uleiuri și grăsimi de origine animală sau vegetală

Filtrare foarte lenta » Filtre grupa 1246: Hartie de filtru cu pori extra-mici utilizata la filtrari foarte dificile spalate cu acid si curatate cu apa demineralizata

Main Features
Filter paper for quantitative analysis FILTER-LAB®are made under the strictest requirements of quality not only of the raw materials used but also of the conditions in which the production processes take place.
For its manufacture we use cellulose fibers and very pure cotton linters whose content in alpha cellulose is virtually 100%. At any rate, the cellulose fibers its natural state contain small quantities of organic and inorganic impurities. It is because of this that these paper filter papers require a special production process.
Once the filter paper is manufactured in the desired physical conditions (weight in grams. Thickness, velocity of filtration, etc.) a washing process with acids is initiated (generally HF an HCI) which concludes with a final cleaning with demineralized water. We get two important properties in the process as the high resistance tot he moist state and the ash content is less than 0.01%.
Because all of this, these filters are specially suitable for filtration with Büchner funnels in quantitative analyses since they meet the requirements of international standards with regard to ash content

Hartii de filtru ultra-pure fabricate din celuloza nobila cu un continut alfa de aproximativ 99% si de cenusa de 0,01% conform normelor precise continutul de cenusa este de aproximativ 0.06%

Aplicatii
industria alimentara, industria farmaceutica, industria chimica, industria petroliera, analiza probe de aer

Main Features
Its main characteristic, furthermore to have a low ashes content under 0.01% it is its high resistance to moist state, for this reason is recommended its use in pressure filtrations or in Büchner funnels in gravimetric analysis of samples with mild acidic or alkaline rating.Likewise, its marked evenness on the surface of the filter allows one to recover most precipitates without the fibers adhering to them.

Application
Ref. 2235. Very fast filtration
Gravimetric analysis with pressure funnel
Analysis of creams and animal fats
Analysis of some minerals and chemical products
Ref. 2240. Medium filtration
Analysis of samples that are mildly alkaline or acidic.
Ref. 2244. Slow filtration
Determination of metals
Recovery of precipitations in the filter’s surface.
