Filter handling for MF method testing has been revolutionized by the EZ-Pak membranes and dispensers. They combine the advantages of ready-to-use, sterile and individually packaged membranes.

The Steritest™ NEO device for liquids in ampoules or collapsing bags contains a needle for easy access to ampopules and a separate vent needle. A special needle adapter facilitates access to collapsing bags. The blue color coding on the ground indicates that the membrane is made of cellulose mischester. The red coding indicates a PVDF membrane. This membrane provides an optimal filtration flow rate for standard products.

If you want to have free chlorine, large particles and organic compounds removed from your tap water, use the Progard® pre-treatment packs. The reverse osmosis membrane (RO) is protected from chlorine oxidation, mineral scaling and organic pollution.

Features & Benefits:

• Ensures optimization of system life and performance

PetriSlides can also be used instead of Petri dishes. An inner ring is located in the transparent cover to ensure that the membrane lies securely on it. Due to its transparency it allows microscopy even if the lid still rests on the PetriSlides. The storage of the PetriSlides is uncomplicated, either in the supplied carton or in slide boxes.

The Millex® Syringe Filter has been specially manufactured for sterilization or clarification of biological solutions. To increase throughput and flow rate, the filter has a larger filtration surface. This also reduces the pressure required to emtpy the syringe. The filters are provided with a quality certification because they are manufactured under a controlled environment and an automated process.

The stacked-disk format of Millipak® filter units eliminates the risk of fiber release from downstream support material.

Features & Benefits:

• No risk of membrane cracking as the 0.22 µm membrane is supported by a rigid plastic disc with channels
• As the membranes are welded onto the support disc, the risk of contamination is considerably reduced
• Minimum dead volume thanks to the large filter surface

Without any filtrate transfer, you can filter into a 50 ml centrifuge tube with the Steriflip® filter unit. Simply screw the filter unit onto your centrifuge tube, tilt it 180 degrees and apply vacuum. The second tube, which is attached to the filter unit, now contains your sterile filtrate.
