Polypropylene Prefilters and Membranes
Související zdroje
Overview
Millipore polypropylene filters are constructed of 100% virgin polypropylene media. They are ideally suited for general clarifying and prefiltration applications including solvents, deionized water and bioburden reduction. They also provide broad thermal compatibility.
The prefilters provide high particle retention, high dirt holding capacity and low pressure drop. They are designed for filtration of organic solvents, but they can also be used, once properly wetted with alcohol, for the filtration of aqueous solutions.

| What is the difference between pore size and pore size distribution? | Whereas pore size is a measure of the diameter of the largest pore, pore size distribution is a measure of the range of pore sizes. The range of pore sizes can be normally distributed, and the spread can be quite narrow (e.g. the ratio of largest to smallest may be less than 2). On the other hand, pore size distribution can be very heterogeneous. In the case of large spreads and heterogeneity, the pore size will be far less predictive of flow rate (either filtration or capillary) than it will be for a membrane with a narrow pore size distribution. It is important to note that the pore size corresponding to the bubble point is not at the middle of the distribution, but is the largest pore. |
