General filtration of laboratory
For unpretentious applications, of routine, it is recommended the papers for filtration type 3 h, 3 hw, 3 m, 3 m/N, 4 b, 1602N. The characteristic of these types is the low price. For laboratory activities that ask a high level of purity, for filtering of the analytical tests, we recommend the use of quantitative and qualitative filter papers.

The Analysis of ground
Besides the filter papers quantitative and qualitative, type132 is usable especially for filtration the extracts of ground, because of the reduced content of phosphates and elements.


Laboratories from brewery industry
On the basis of many years of experience there was developed types 6 and 4b, suitable for malt’s filtration and type 603 which can be used for removing gases from beer precursor to analysis. These filter papers are of raw materials selected and characterized by a special uniformity that assures a reproducibility of exception for the analyses’ results. This reason for which the papers of “boiling beer” Filtrak are used for decades in the famous brewery industries from Cehia and Saxonia.Demand offer

Filterable aggregates of 25 mm were projected for the filtration under vacuum of medium volumes of watery solutions or organic, for the tests filtration in HPLC and for the analysis of particles and/or of contaminated materials from microbiological tests. There can be delivered with glass filters or stainless steel. Filters from stainless steel are recommended for the tests that contain proteins or for viscous tests.

Specifications:
-The stand for the filterable membrane is from borosicate glass;
-The filterable: 2.1 cm;
-The diameter 25 mm The test vessel: the volume 25 ml; gradation up to 15 mlDemand offer

Filterable aggregates from glass of 47 mm were projected for eluents’filtration HPLC, for greater volumes filtration of the watery solutions under vacuum or solutions with organic solvents.

We offer three models of filterable complete aggregates. The filterable aggregates with sintered glass stand (A,B), we recommend them for general application. The filterable aggregates from stainless steel (C) can be completely dismantled, this facilitating their cleaning and reducing the possibility of contamination, from this reason they are recommended for filtrations that have like purpose deproteinization or for microliter pure filtrations. At model (A) the unity of filtration with a sharpen strip is connected to 1 stopper bottle with an outer sharpen strip .

At the models (B) and (C) the unit of filtration is connected with a rubber stopper to any stopper bottle of standard vacuum.Demand offer
