Nanofiltration - Wikipedia

Nanofiltration - Wikipedia

Advantages and disadvantages. One of the main advantages of nanofiltration as a method of softening water is that during the process of retaining calcium and magnesium ions while passing smaller hydrated monovalent ions, filtration is performed without adding extra sodium ions, as used in ion exchangers. Many separation processes do not operate at room temperature (e.g. …

Cell Handling - Eppendorf Handling Solutions

Cell culture work often implies the cultivation of various cell lines for different ongoing experiments. The simultaneous nourishment of different cell lines in a biosafety cabinet might save some time during a busy day in the laboratory but dramatically increases the risk of cross-contamination and can thus seriously impair the entire experiment.

The method is rapid and accurate within a range of concentrations; however, if the culture is too concentrated, more than one cell may pass through the aperture at any given time and skew the results. This method also does not differentiate between live and dead cells. Direct counts provide an estimate of the total number of cells in a sample.
