membrane filter

Membrane filters are widely used for filtering both drinking water and sewage.

Drinking water supplies in Europe had been compromised by the war and membrane filters were used to test for water safety.

The air smelt bad, membrane filters couldn't cope with the body gases, C02 was building up, oxygen reserves were almost exhausted.

A highspeed form of microfiltration that has the wine flow across a membrane filter rather than through it.

For no real reason other than tradition samples are normally passed through a forty five mu sieve or membrane filter.

Most Milli-Q systems dispense the water through a 0.22 μm membrane filter.

At other times, skimming is also a cost-efficient method to remove most of the oil before using membrane filters and chemical processes.

We next modified the flow cells with a disposable, microporous membrane filter for lymphocyte capture.

Membrane filters are widely used in biotechnology and food and beverage applications where sterile product is required.

In a membrane filter, a thin, porous membrane is bound to the scrim.

For drinking water, membrane filters can remove virtually all particles larger than 0.2 um-including giardia and cryptosporidium.

PTFE membrane filters are among the most efficient used in industrial air filtration applications.

To achieve higher total throughput or to avoid premature blockage, pre-filters might be used to protect small pore membrane filters.

To ensure proper functioning of the filter, the membrane filters are integrity tested post-use and in occasions pre-use.

Various concentration methods are applied: membrane filter, Knott's concentration method, and sedimentation technique.

It is also used to examine particles caught in transparent membrane filters (e.g., in analysis of airborne dust).

Membrane filters found immediate application in the field of microbiology and in particular in assessment of safe drinking water.

Membrane filters can be blinded with grease or abraded by suspended grit and lack a clarifier's flexibility to pass peak flows.

The "'Membrane Filter method"' is used when there is a presence of either damaged diatoms in the sample (result of pollutants) or inorganic materials.

The second stage of processing involves filtration, typically using a filtration chain with the final filtration being triple sterile 0.1 micrometre membrane filters.

Growers there, like their counterparts in California, France and Italy, are using such technical jargon as "stainless steel," "cold fermentation" and "membrane filters."

The formazan accumulated intracellularly and could be visualized by epifluorescence microscopy in wet-mount preparations, on polycarbonate membrane filter surfaces, or directly in some biofilms.

The majority of today's filters are more correctly called "chamber filter press", "Membrane filter press", or "Membrane Plate Filter".

By 1959, Millipore made porous membrane filters of cellulose esters or other materials which resembled paper in sheet form, and were brittle when dry but friable when wet.

The buccal cells were deposited by vacuum onto a membrane filter (5 m pore size, Millipore Ltd) and washed free of unbound bacteria with phosphate buffered saline.
