Waters has introduced a new line of sample vials for high performance liquid chromatography and gas chromatography analysis. The vials are certified to be contaminant-free.
The newly launched glass vials are made from Type I, 33 expansion glass with a low detectable free ion content, the company said. The septum is tested for residual levels of low molecular weight silicone polymer by head space gas chromatography. In addition, each lot of vials, with cap and septum, is tested with gradient HPLC to verify cleanliness.
Adriadne Genomics has released its PathwayAssist 3.0 software for visualization and analysis of biological pathways. The new software includes a database of over 500,000 molecular interactions, improved visualization tools, and wizards for data import and export.
New visualization features of the software include advanced layout options and resizable pictures of organelles and cell localization compartments. Pathway viewing has been enhanced with a new magnifier window, schematic graphics for large pathways, and grid and node alignment options.
