Analytical Sample Preparation

The image depicts a laboratory manifold with a white base and structure, featuring a dial gauge and eight glass tubes with stopcocks.

Our sample preparation and purification portfolio includes products for solid phase extraction (SPE), QuEChERS, solid phase microextraction (SPME), air monitoring, sample decomposition, purge and trap techniques, flash chromatography, and LPLC. Our comprehensive range features products for clinical, pharmaceutical, environmental sample prep, phospholipid removal, dioxin and PCB sample analysis, and desorption tubes and adsorbent cartridges for active and passive air sampling.

The image showcases various pieces of scientific glassware, including a beaker, an Erlenmeyer flask, and a round-bottom flask, each adorned with a colorful DNA double helix symbol. This suggests the equipment is used for molecular biology or genetics experiments.

Laboratory Filter Holders

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.

Millipore® Filter Membranes

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.
