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:
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™ 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 in a broad selection of membrane filters with both sterile and

Samplicity™-System: Efficient filtration of hard-to-filter samples
Compared to syringe filtration of viscous or particulate-laden samples, which required excessive manual force and greater filtration time per sample, the Samplicity™ filtration system filtered even highly viscous samples in seconds, with minimal manual force.
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 the repetitive and critical tasks accurate, quick and easy.
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.
Merck Millex™-GP Sterile Syringe Filter Units with PES Membrane, 0.22 μm (Research Use Only)
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.

Achieve better reproducibility, signal-to-noise ratio, & robustness. Brows some of Merck's western blotting products to improve your outcomes with optimized tools for your Western blots. Explore our products designed to improve key steps of the western blotting workflow.
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.
Choosing the right Ultrafiltration Membrane makes a difference. See a comparison study of retention efficiency for different Membrane types.
