The Isopore membrane is a polycarbonate, track-etched screen filter recommended for analyses of airborne contaminants and other particles using optical or electron microscopy. The Isopore membrane has a smooth, glass-like surface for clearer sample observation.

Biologically inert mixtures of cellulose acetate and cellulose nitrate have made MF-Millipore membrane filters one of the most widely used membranes in analytical and research applications. Triton surfactant-free MF-Millipore filters contain minimum amounts of wetting agent and have a lower water extractable content than standard MF-Millipore filters.

Clarification of particle-laden solutions prior to instrument analysis
Two to four times greater throughput than syringe filters without prefilters. Compatible with automated systems, including Zymark's workstations. Low-extractable polypropylene housing.

Milli-Q® Ultrapure Water Purification Systems
The standard for ultrapure water in the laboratory
Each of the five new Milli-Q systems is designed to specifically target contaminants detrimental to particular applications such as HPLC, molecular biology and ICP-MS. The systems incorporate a high precision resistivity monitor that records conductivity or resistivity (compensated or not at 25 °C), and also feature a built-in TOC monitor with a 1-999 ppb detection range for accurate analysis of organics.

Millipak disposable filter units are stacked disc filters designed for the removal of particles and microorganisms from liquids and gases. The stacked disc design allows minimal hold-up volume and particle shedding, making Millipak units ideally suited for high value-added applications.

Millipore Express® PLUS Membrane Filters
Polyethersulfone
The Millipore Express PLUS membrane provides ultrafast filtration of tissue culture media, additives, buffers and other aqueous solutions. This high-throughput, low-protein-binding membrane is also used in many of the ready-to-use sterile filtration devices available from Millipore.

Fluoropore™, Mitex™, LCR and Omnipore™ Membrane Filters
Supported, unsupported and hydrophilized PTFE
Fluoropore membrane is a hydrophobic PTFE membrane bonded to a high density polyethylene support (FHUP has no backing).The membrane has broad chemical compatibility.
