Laboratory Filtration

Millipore^® membranes have supported laboratory filtration in academic, pharmaceutical, and industrial sectors since the 1950s. We provide a range of membrane chemistries including MF-Millipore^® mixed cellulose esters, Durapore^® PVDF, Millipore Express^® PLUS polyethersulfone, as well as hydrophilic and hydrophobic PTFE.

An extensive selection of glass, stainless steel, and plastic filter holders for use with cut disc membrane filters for liquid and gas filtration, including syringe filter holders, in-line filter housings, and filter holders for vacuum and pressure filtration. 

High performance sterile and nonsterile syringe filters offered in a variety of membrane materials and pore sizes, tailored for sample preparation for HPLC, UHPLC, ion chromatography, dissolution testing, and other analyses.

Whatman^® filter papers for qualitative and quantitative analysis. 

Filter membranes for filtering organic solvents and aqueous solutions for HPLC and other analytical methods, and for use in sample preparation, clarification, particulate removal, sampling, filter sterilization, and separation and retentate techniques.

Filtration devices for concentration and preparation of biological and environmental samples for downstream processing. 

Bottle-top vacuum filtration units and systems for routine filtration of buffers, solvents, and culture media, syringeless filters for HPLC and UHPLC sample preparation, pressure filter funnels for solute and compound drying, and analytical filter funnels for microbiological testing.
