The phrase "absorbent filter" is correct and usable in written English.
It can be used to describe a type of filter that has the ability to soak up or retain liquids or particles, often in contexts related to filtration systems or materials.
Example: "The laboratory used an absorbent filter to ensure that all contaminants were removed from the water sample."
Alternatives: "sorbent filter" or "filtering medium".
Blood samples were absorbed onto Whatman FTA Elute absorbent filter paper in Grande Comore, Moheli, and Anjouan islands, on Whatman 903 Protein Saver filter paper (Whatman Inc., Florham Park, NJ, USA) in Mayotte, and collected into Vacutainer tubes (Becton Dickinson, Le Pont-De-Claix, France) in Marseille.
All roots were dried on absorbent filter paper and then spread over a rectangular, transparent, plastic sheet so that no two segments touched.
We anticipated that absorbent filter paper would maximize sample collection.
Excess liquid was removed by careful blotting with absorbent filter paper leaving thin biconcave liquid films spanning the holes of the polymer support.
Specially formulated absorbent filter papers were used for collecting a drop of blood for infants under 18 months of age for molecular diagnosis through PCR [ 28].
A droplet of cubosomes dispersion was placed on a 200 mesh carbon-coated copper grid, and the excess fluid was removed by an absorbent filter paper.
Modern chemical analysis is now done automatically by a device with absorbent filters that also identifies the separated molecules by measuring their mass, velocity and charge.
Absorbent filters (37 mm; Millipore, Billerica, MA, USA) were thoroughly soaked with the bacteria/sucrose solution and one filter was placed into each vial.
The criteria to control radon leakage and radon emanation coefficient are given for three types of test samples: (a) building materials, (b) natural materials of mineral origin (sands, clays, rocks etc)., and (c) artificial materials, such as absorbents, filters, radioactive wastes.
Research on one of these nanomaterials, cerium oxide (ceria) nanoparticles, has shown that its material properties are extremely well suited for a lot of applications; ceria can be employed as the optical active agent in UV absorbents and filters [7], gas sensors [8], and bioimaging media [9].
In recent years, cerium oxide nanoparticles (CeO2 NPs) have been intensively studied owing to their wide applications and unique properties in UV absorbents and filters, gas sensors, catalytic wet oxidation, catalysts in the fuel cell technology, engine exhaust catalysts, photocatalytic oxidation of water, NO removal, electrolyzers, solid electrolytes and so on (Goharshadi et al. 2011).
