Rapid Microbiological Testing of Filterable Products
A membrane filtration method is included for enumeration of microorganisms in filterable samples, based on culturing microorganisms from the test sample.
Single packed or dispenser-ready sterile membranes can be used for colony counting, particle testing, microscopy and sterility testing. The membrane filters are
Cellulose Membrane Filters Used in Pharmaceuticals
These filters have different pores sizes and used for different purposes accordingly. Membrane filters are used in various pharmaceutical activities. Cellulose
There are four levels of membrane filtration. These levels are (from largest to smallest pore size): microfiltration, ultrafiltration, nanofiltration, and
Sterile units are ideal for microbiological testing of water quality, food, raw material, sterility, and product quality. Filtration units with a multitude of
Filters and membranes designed to retain bacteria or other microbiological organisms for sample preparation, microbiological studies, and filtration of
Membrane filter techniques are widely used for the enumeration of bacteria from water samples. In this method, the bacterial cells are filtered through
In the membrane filter technique, water is drawn through a thin filter (see Figure 3). Filters with a vari- ety of pore sizes are available. Pores of 0.45 µm
