Description
Microfilter cartridges with porosity 3 are fine-grade laboratory filter inserts measuring 13 x 25 mm, with a tube diameter of 8 mm and a height of 200 mm. Designed for use in gas washing bottles, Woulff bottles, and similar apparatus, they provide a defined porous barrier for gas scrubbing, particulate control, and protective filtration steps. Porosity grade 3 represents a finer option within the cartridge range, appropriate when tighter retention is preferred over the coarser porosity grades. Uniform geometry supports reliable seating and interchangeability in compatible glassware trains. Supplied in packs of 10 pc(s) weighing 0,230 kg, the cartridges are practical for multi-station laboratories and for maintaining spare stock. Available from manufacturer DWK Life Sciences, they align with standard labware practices for gas-treatment assemblies and related vessel systems. Specifying porosity 3 together with the 13 x 25 mm section, 8 mm tube diameter, and 200 mm height enables precise matching to existing setups in analytical, research, and educational laboratories that require consistent microfilter performance.
This article is part of Test tubes, in Tubes & vials.

Questions about Microfilter cartridges, porosity 3, 13 x 25 mm, tube Ø 8 mm, H 200 mm
What is this article?
Microfilter cartridges, porosity 3, 13 x 25 mm, tube Ø 8 mm, H 200 mm is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Test tubes, inside Tubes & vials, in Labware.
A test tube is the open cylindrical vessel for a small liquid, in borosilicate glass or in plastic. Rimmed and rimless mouths differ. The size is diameter by length. It is not graduated for a result, and a glass tube that will be centrifuged has a force limit.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
