Memtrex - Pleated Filtration

The Osmonics membrane filtration portfolio, Memtrex, has been developed over years to provide in-line security to suit a wide spectrum of applications. To claim such a broad capability, Osmonics employs the use of four types of media in seven formulations, ranging from 0.03 to 1 micron absolute ratings.

Memtrex polyethersulfone

New for 2003 is the Osmonics' Polyethersulfone (PES) membrane, a membrane that has been optimized with the latest membrane technology to produce a filtration media with enhanced porosity that results in low differential pressures, high throughputs, extended filter life, and reduced processing time. The PES has optimum membrane performance in final and pre-filtration applications, providing outstanding particle retention while maintaining high flow rates. The actual membrane is cast by Osmonics ensuring total quality control and the ability to modify the media to suit individual application. This new media is inherently hydrophilic, allowing for quick wet out. Osmonics' PES filter cartridges, coded MMP General grade, are manufactured utilizing only two materials of construction, polypropylene components and supports, and PES membrane. Thermal bonding assembly technology eliminates extractables due to adhesives and enhances the filters' resistance to severe sanitizing agents, such as hot water, hydrogen peroxide and peracetic acid, as well as offering a broad range of compatibility with other aggressive fluids in both the high and low pH arena. Because of its low preservative and protein binding characteristics, Osmonics' PES media is an excellent choice for the reduction of microbial bioburden and particulate loads when filtering buffers and other biological solutions without sacrificing flow rates and filter life. Each filter is integrity-tested during the manufacturing process to ensure consistent and reliable field performance.

Memtrex polyethersulfone - general grade

Brings economy to submicron filtration 82ºC Polyethersulfone Incorporating the new PES Media across the grade, the 0.2 micron version of the MMP is Fileder's most popular sub-micron cartridge due to its low cost and meeting the general requirements of most 0.2 pure water, acid, base and solvent filtration applications.

Junior Style Pleated Range

• Small-scale, low-cost, absolute filtration
• 40°C @ 2 bar
• 80°C @ 0.3 bar

The filtration industry has standardised on the multiples of 10" by 2 3/4" cartridge which offers solutions to most applications. This has resulted in many low-flow and batch process lines unnecessarily having the expense of oversized and under-utilised filtration. The junior style cartridge (5.3" x 2.2") addresses this economically with a range of half-size elements in four medias, all absolute rated.

Polyethersulfone (PES):
PES has very low protein binding characteristics and offers higher flow rates, higher throughputs (longer life) and lower extractables than cellulosic, PVDF or nylon membranes. PES is ideal for water and biological/pharmaceutical filtration. Surface area - 1,900cm2.

Polypropylene (HD):

This microfine continuous filament PP material is formed into a variety of media by varying the filament's diameter and layer density. Using a series of graded media layers an optimum matrix of retention, high-flow and long-life is achieved. Surface area - 1,450cm2.

PTFE (TF):

PTFE is the most inherently hydrophobic microporous membrane available today. PTFE is most commonly used for venting. However, its durability and chemical resistance lend itself to a variety of applications. TF versions feature GORE-TEXTM expanded PTFE membrane. Surface area - 1,800cm2.

Nylon (AS):

No wetting agents are needed to facilitate priming with aqueous solutions because of nylon's inherently hydrophilic nature. Nylon offers a consistent performance relative to bubble points, flow rates, throughput, thickness and retention. This membrane is ideal for filtering a variety of aqueous solutions. Surface area - 1,450cm2.

Filter sleeves

• Small, reuseable, inexpensive filtration
• 40ºC
• Nylon, Polyethylene

Filter sleeves provide surface filtration in the most popular configuration, 10", that can be installed into all conventional 10" filter housings. The range consists of six grades from 25 to 350 micron. For finer filtration, 25 micron disposable porous polyethylene should be used, with coarser applications using the nylon mesh sleeves in 50 micron (white), 100 micron (blue), 150 micron (brown), 200 micron (green), 350 micron (grey), which are colour coded for convenience.
