Samplicity G2 Filtration System for HPLC Samples

The Better Way to Use Millex Filters

For chromatographers who filter dozens of HPLC samples a day through Millex™ syringe filters, especially for hard-to-filter, viscous or particulate-laden samples, traditional filtration can lead to manual fatigue. Nevertheless, they stick with Millex™ filters, which are specified in numerous HPLC methods and standard operating procedures. The Samplicity™ G2 multi-sample filtration system enables you to enjoy Millex™ quality, but skip the pain of manual syringe filtration.

The newest Samplicity™ G2 system gives you:

  • Vacuum filtration of 1-8 samples in seconds directly into HPLC vials
  • An ergonomic alternative to syringe filters
  • Broader membrane selection
  • Compatibility with any protocol or SOP specifying 33 mm Millex™ filters

Millex Syringe Filters

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

Water Purification

As the most commonly used solvent, your laboratory relies heavily on the quality of your water.

MilliporeSigma offers solutions for: Type 1 - Ultrapure, Type 2 - Pure, Type 3 - RiOS

milliq-integral-qpod-millipak

Type 1 - Ultrapure

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.


emd-millipore-elix

Type 2 - Pure

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.

From tap to pure:


emd-millipore-rios

Type 3 - RiOS

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.
