The Heart of Science

Merck's purpose is to solve the toughest problems in life science by collaborating with the global scientific community. Through this, Merck aims to accelerate access to better health for people everywhere. Merck products provide scientists and engineers with best-in-class lab materials, technologies, and services. Merck is dedicated to making research and biotech production simpler, faster, and safer.

An Exhaustive Portfolio

The path to new discoveries must be laid on a solid foundation. Backed by decades of research, Merck's exhaustive portfolio of fundamental filters and supporting hardware has helped generations of scientists reach new milestones.

With the needs of today’s scientists foremost in our minds we have continued to evolve, ensuring our products can continue to serve as the cornerstone for your latest innovation.

Membrane Filtration

Millipore™ membranes have supported laboratory filtration in the academic, pharmaceutical, and industrial sectors since the 1950s. We provide a range of membrane chemistries including MF-Millipore™ mixed cellulose esters, Durapore™ PVDF, and Millipore Express™ PLUS polyethersulfone, as well as hydrophilic and hydrophobic PTFE.
View some of Merck's most popular membrane filtration products below:

Hardware and Accessories

Filter housings are used in conjunction with cut disc membrane filters to provide structural support and create a seal around the membrane to prevent filtrate contamination. Reusable syringe filter holders are suited for filtering or clearing small amounts of liquid where a replaceable or removable filter is desired. Filter holders for vacuum and pressure filtration are available in a variety of formats and sizes. View some of Merck's most popular filtration hardware and accessory items below:

Multiply Your Success with MultiScreen™ and Millicell™ Plates

Multiwell plates enable simple, rapid, automation-compatible preparation and analysis of multiple samples to fulfill the requirements of life science, environmental, analytical, clinical, forensic, diagnostic, and industrial workflows.

MultiScreen™ plates meet specific performance criteria for sample preparation and assay methodology requiring low non-specific binding of protein and drug analytes, solvent compatibility, and sample throughput. MultiScreen™ plates are used to prepare and collect samples for analysis and miniaturize assays in 96- or 384-well formats, while Millicell™ products offer the versatility of 6, 12, 24, or 96 wells for cell culture applications.

MultiScreen™

MultiScreen™ filter plates are designed to work productively with sensitive detection and imaging systems, providing dependable and robust sample handling and precision transfer.

MultiScreen™ filtration plates are offered with a broad selection of membrane filters and in both sterile and
non-sterile forms.

Clean Data Starts with Clean Samples

Protect your results with Millex™ syringe filters. We offer a broad range of membranes,  pore sizes,and filter diameters to meet your needs. Whether you are performing HPLC, LC-MS, ion chromatography, dissolution testing, or protein analysis, Millex™ syringe filters support high sample recoveries while providing consistent, reliable filtration.

With over 50 years of expertise, we are constantly innovating new filtration tools to offer rapid and efficient solutions tailored for you. Use our selector to find the ideal syringe filter for your sample.

Sterile Filtration

Prepare cell culture media with our sterile filters. With industry leading innovative designs for filtration devices and 60 years of membrane technology expertise, we offer a wide range of solutions to make repetitive and critical tasks accurate, quick, and easy.

Syringe Filters

Millex™ syringe filters provide convenient sterilization of small volumes and are ideal for solutions such as antibiotics and tissue culture additives. Their unsurpassed quality and consistency of results has led to the development of many sample preparation methods that specify Millex™ filters.

Bottle-Top Filters

Stericup™ and Steritop™ sterile filtration devices combine superior flow rates and throughput with low non-specific binding and a stable, no-tip design. Membranes with low protein binding ensure that key growth factors and proteins won’t be absorbed into the filter.

Others

Merck provides many further sterile filtration devices to improve on your sample filtration needs. These items include Merck's Steriflip™, Sterivex™, Steripak™, and Stericap™ products. Find a small selection of these convenient and reliable devices below:

Cell Culture Products

Cell culture is fundamental in life science research and development. Whether your goal is to establish relevant cell models to probe complex biology, establish drug discovery and drug development assays, or produce recombinant proteins or therapeutics, we have everything you need to advance your science.

Our cell culture workflow portfolio, advanced cell culture solutions, cell counting and imaging equipment, cultureware, extracellular matrices, hydrogels, sterile filtration consumables, reagents, media, sera, and growth factors offer quality essentials for 2D and 3D cell culture experiments.

Extraction, Isolation, Purification, Separation, and Detection

Our membrane engineers have developed devices expressly for desalting, concentrating, and buffer exchange that save your proteins and save you time and protocol steps. A comprehensive offering of protein preparation products provides gentle extraction, high-yield isolation and purification, and application-verified detection tools for techniques like electrophoresis as well as Western blot, ELISA, and multiplex and mass spectrometry.

 

UF Protein Concentration

UF Protein Concentration

Concentrate your protein, don’t lose it. Recover protein reliably when you concentrate with Amicon™ Ultra filters. We’ve engineered Amicon™ Ultra filters with low-binding Ultracel™ regenerated cellulose membranes to ensure more precise molecular weight cut-offs.

Rethink Western Blotting

Rethink Western Blotting

Merck's Western Blotting products are designed to improve key steps of the blotting process. Achieve better reproducibility, signal-to-noise, and robustness with tools optimized for your workflow, such as those illustrated below:

Filter - Membrane

Filter - Membrane

Downstream analyses require that proteins, nucleic acids, virus particles, and other biomolecules are solubilized in their native form at an appropriate concentration. Ultrafiltration methods can be used to gently and efficiently concentrate biological or environmental samples by removing excess liquid or buffer. A variety of ultrafiltration devices are available to rapidly concentrate proteins and other biomolecules with high recovery.
