Nuclease-free water at your fingertips
2 Apr 2023Nuclease-free glassware and reagents are required for many molecular biology applications. Chemical treatment with diethylpyrocarbonate (DEPC) has long been a common practice to generate nuclease-free water, but this method has several drawbacks.
In this application note, Merck describes how an ultrafiltration cartridge can be placed at the outlet of a water purification system to deliver nuclease-free ultrapure water that can directly be used for experiments.

FiltrationFiltration and microfiltration are used to separate solids, particulates or large molecules from fluids (liquid or gases) in order to purify the filtrate. Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration, smaller particulates may require additional force for timely separation. Microfiltration equipment includes vacuum filters, as well as positive pressure, crossflow and centrifugal filtration devices.

These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.Ultrapure WaterUltrapure water is the highest purity water and contains the lowest levels of organic and inorganic contaminants, particulates and microorganisms.UltrafiltrationPure WaterPure water is processed to remove significant level of contaminants and is suitable for use in many laboratory applications.
