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

• Depth filtration for particle removal

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.

For sterilisation of aqueous solutions. The filter units are suitable for use with syringes, peristaltic pumps and pressure vessels.

• Sterile
• Hydrophilic
• Low protein binding
• Luer-Lock inside

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.

Solutions of any macromolecules, simple and efficient, desalt and concentrate. Suitable for any centrifuge holding 1.5 ml tubes.

Features & Benefits:

• Even with diluted solutions the recovery is more than 95%.
• Reverse spin to maximize recovery even in the smallest sample
• Storage of filtrate or concentrated sample, very easy in standard microcentrifuge tubes
• concentration factor up to 100 x

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

High sample recovery by ultrafiltration, even in diluted samples, and fast sample processing are offered by Amicon® ultra-centrifugal filters. The centrifugal filters, for fastest and most efficient concentrations, are specially designed for sensitive downstream applications. The Ultracel-10 centrifugal filters have a NMWL (Nominal Molecular Weight Limit) of 10 kDa.

Features & Benefits:

• Prevents rotation to dryness
• Providing a predictable concentration factor
• No calibration necessary if several samples are to be run in parallel
• Vertical membrane, aligned with filtrate
• Less clogging, faster filtration and less waste

• Robust, slim unit that prevents leakage

Durapore® PVDF membranes are characterized by high throughput and high flow rate. To maximize recovery and minimize interaction with your sample, the membrane has very low protein binding.

Features & Benefits:

• Can be sterilized by ethylene oxide and gamma irradiation
• Available in different pore sizes

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.

MF-Millipore™ Membranes have a biologically inert mixture of cellulose acetate and cellulose nitrate. The MF-Millipore™ filters without Triton® surfactant have a lower water extractable content compared to the standard MF-Millipore™ filters and contain a minimal amount of wetting agent.

Features & Benefits:

• Manifold filter for biological and environmental monitoring applications
• available in various pore sizes
• white or black coloured
• Freely selectable whether with or without grid surface
• Compatible with ethylene oxide, gamma irradiation and autoclave sterilization methods
