UltraPure, nylon 6,6 membrane cartridge by Exova

Description

The UltraPure is a nylon 6,6 membrane filter cartridge for microorganism control and fluid clarification in industrial processes. It works as a final filter or as upstream protection for final filters, in bottled water, wine, unpasteurized alcoholic beverages, and pharmaceutical and biological solutions.

The membrane is naturally hydrophilic: it filters with high flow rates and a very low pressure drop. The 0.1 and 0.2 µm ratings retain more than 10⁷ Brevundimonas diminuta per cm², according to the FDA definition of sterilizing-grade filters; the 0.1 µm rating also retains more than 10⁴ Acholeplasma laidlawii per cm².

It withstands repeated steam sterilizations, in-line or in an autoclave, and sanitization with hot water at 80 °C and chemical cleaning and disinfection agents, so it can be reused. It is manufactured in an ISO 7 cleanroom.

Frequently asked questions

Can it be used as a sterilizing filter?

The 0.1 and 0.2 µm ratings retain more than 10⁷ Brevundimonas diminuta per cm², according to the FDA definition of sterilizing-grade filters. The 0.1 µm rating also retains more than 10⁴ Acholeplasma laidlawii per cm².

Which processes is it used in?

In the final filtration of bottled water, wine, and unpasteurized alcoholic beverages, in pharmaceutical and biological solutions, and as a prefilter ahead of final filters.

Can it be steam-sterilized in place?

Yes. It withstands multiple cycles of 30 to 60 minutes at 121 °C, with in-line steam or in an autoclave, and the cartridge can be reused. It is recommended only for single-open-end cartridges with internal reinforcement at the 226 or 222 O-ring fitting.

Which chemicals can be used for sanitizing and cleaning?

Peracetic acid up to 1 % (10,000 ppm) at room temperature for sanitizing, and sodium hydroxide up to 1 % (10,000 ppm) for cleaning, in multiple cycles of 30 to 60 minutes.

What lengths and connections are available?

A 2.75″ (70 mm) diameter and lengths of 10″, 20″, 30″, and 40″. It is offered with double 226 or 222 O-rings, with a fin or a flat end, or as double open end (DOE).
