Problem: The assessment of cell concentration and viability is an important step in the characterization of cell health. This information can be used for monitoring proliferation rates, optimizing growth conditions and normalizing cell data for further studies, such as assessing the impacts of cytotoxic compounds.
Current methods rely on multiple, sometimes complex, instrument platforms to provide these answers, reducing flexibility and increasing research costs. Other, simpler methods provide inconsistent results due to their dependence on single-uptake dyes, which do not effectively discriminate between the various states of cell demise. As a result, there is a crucial need for analytical methods that efficiently provide reproducible count and viability data.

Problem: Solvents are used in virtually every laboratory to perform routine research procedures as well as product quality control and medical and diagnostic tests. Laboratory staff are responsible for the documentation, staging, storage and transport of solvents, which compromises valuable time spent on research.

Today, newer purification technologies have proven able to compete with long-established distillation. Following a brief review of these purification technologies are data for performances of a single and double distillation system, and the Millipore Elix UV system.

Laboratories everywhere rely on water purification systems to produce the pure water they need for their daily procedures and experiments. Such systems, including those from EMD Millipore, use a combination of several purification technologies in order to remove contaminants present in tap water.
