Water Purification Application Notes to Improve Your Life Sciences Research

Tips and Tricks for High Purity Water Handling in the LC-MS Laboratory
This poster, from EMD Millipore, is designed to help analysts critically evaluate the potential risks involved in poor ultrapure water handling, including the effect of laboratory environment and long high purity water storage, collection container material, equipment cleaning, and poor practices of water purification system.

The Gemini Bacterial Challenge
Discover how the Gemini Ultra High-Purity Water System, from Aeries Filterworks, performs in a bacterial challenge test completed by Analytical Services, Inc. The method determines the quality of viable bacteria in the Gemini effluent when challenged at the inlet by a high concentration of a specific test organism.

Blotting Techniques Enhanced by the Use of Type I Ultrapure Water
Northern, Southern and Western blotting techniques depend on the use of Type I ultrapure water to obtain high quality results. Water used for blotting purposes should be nuclease-, endotoxin- and bacteria-free to protect the DNA, RNA and proteins under investigation. This application note demonstrates how ultrapure water should be used for the preparation of samples, buffers, reagents, gels and rinsing solutions, using the PURELAB flex from ELGA LabWater.

Production of Ultrapure Water for RNase-Sensitive Applications
In this application note, removal of RNases by ultrafiltration is compared to chemical inactivation by DEPC treatment. Ultrafiltration cartridges included in EMD Millipore water purification systems are an effective alternative to DEPC treatment, allowing delivery of highpurity RNase-free water on-demand (based on the results of several experiments on RNA preparation, RNA digestion, an RNA stability test and dosage of RNases).
