Prepare your cell culture media with sterile filters from MilliporeSigma. With innovative filtration devices and more than 50 years of membrane technology expertise, MilliporeSigma offers a wide range of options to make each critical step quick, easy and accurate.

Our MultiScreen™ and Millicell™ Plates and Inserts provide maximum user convenience and reliability for cell culture. With them, cell growth, structure and function more closely replicate in vivoconditions. And the Millicell™ EZ SLIDE brings enhanced features and a unique design that helps you spend less time dealing with clumsy devices and more time on your all-important cell culture research.

MilliporeSigma supports every step of your sample preparation, from protein extraction and purification to concentration and desalting, offering a wide selection of ultrafiltration devices, magnetic beads and more.

Why spend your time on arduous sample preparation protocols when you can focus your efforts on exciting experiments? Purify and concentrate your proteins more efficiently, and your next discovery is only a step away.

MilliporeSigma offers five different transfer membranes, each optimized for different protein blotting applications. Or try blotting sandwiches that feature pre-cut sheets of membrane and blotting filter paper.

MilliporeSigma Reagents are precisely developed and produced to give you reliable and reproducible results across all your applications.

• Bløk™: Ready-to-use, chemical-based, protein-free blocker that removes background risk
• Luminata™: Premixed HRP substrates that offer the right sensitivity at the right price
• Reblot™: Room-temperature stripping in 15 minutes without the smell

Millex syringe filters set the standard for reliable small-volume sterile filtration.

• Low Extractables, Low Binding 
  A variety of membranes and housings ensure compatibility with a range of solutions
• Faster Flow Rate 
  33 mm Millex filters have 20% more filter surface area for significantly higher flow rate and throughput

• Low Hold-Up Volume 
  Despite the increased membrane area in the 33 mm Millex filters, the hold-up volume (after air purge) has been reduced to 80 µL, a 20% decrease over 25 mm filters
• Higher Operating Pressure 
  Millex 33 mm filters can withstand maximum housing pressure of 150 psig (10-bar) so that solutions filter faster

The machines that keep global industries running need clean parts, fuel, and hydraulic fluids that are free of particles and other contamination.

Whether you need to collect air to monitor particulate contamination, or analyze soil or water for hazardous chemicals, MilliporeSigma can supply the expertise, products, and protocols to ensure results that are compliant with regulatory requirements. MilliporeSigma products designed for environmental applications have been developed for use with standard methods, including those of NIOSH, OSHA, and ASTM.

Particle contamination is a concern during the processing, manufacturing, and packaging of pharmaceuticals, foods, and mechanical and electrical components. MilliporeSigma has applied its extensive filtration expertise to a broad range of products optimized to help you comply with ever-decreasing detection limits in occupational and environmental monitoring.

MilliporeSigma offers a Zero Head Space Extractor system for sample extraction that meets the requirements of the EPA's Toxicity Characteristic Leaching Procedure (TCLP), plus a variety of filters, holders, and manifolds optimized to deliver superior results during downstream analyses.

The MilliporeSigma family of certified sample preparation devices provide a disposable, yet reliable method for collecting and preparing environmental samples for downstream analysis. From groundwater collection to chromatographic analysis, there is a device to simplify your procedure and improve your results.

Several MilliporeSigma water systems are designed to produce ultrapure (Type 1) water. Some can operate directly from tap (potable) water and others from pure water (Elix, RiOs, distilled or DI water).

The selection of the proper ultrapure water system for your laboratory will depend on several parameters such as: feed water available in the laboratory, instant and daily volume needs of ultrapure water or ultrapure and pure water, the quality of monitoring of water quality and the level of certification required and several other points.

Several MilliporeSigma water systems are designed to produce pure water (Type 2), combining several purification technologies suitable for applications like buffer preparation, pH solution preparation and microbiological media preparation and feed to laboratory systems.

The production of pure water is indispensable in any laboratory. However, for most users, the production of pure water involves high costs and extensive maintenance due to inefficient or outdated water purification systems. Furthermore, most water purification systems cannot guarantee the production of consistently pure water quality.

Several MilliporeSigma water systems are designed to produce pure water (Type 3) combining several purification technologies suitable for applications that feed to: washing machines for final rinsing of glassware, heating baths, autoclaves, etc.
