The lyophilized lysate (Charles River Endosafe R 15006) was dissolved in ultrapure
water obtained from the arium pro VF system and frozen by portions in pyrogen-free test tubes.
Removing most of the water during a careful, two-day drying process yields hard, glassy materials with an interior Shea likesns to a "rat's nest." Such sol-gel reactions are becoming increasingly important for making ultrapure
glasses, ceramics, coatings and fibers, the researchers write in the November/December CHEMISTRY OF MATERIALS.
The all-in-one system produces high-quality pure and ultrapure
water--directly from tap water--for a variety of applications.
The SYGEF[R] PVDF HP Flex Tubing System offers a cost-effective solution for the conveyance of ultrapure
water and chemicals versus PFA (perfluoroalkoxy) and FEP (fluorinated ethylene propylene) resin based tubing systems.
The idea of using the near-weightless or microgravity environment of space to produce new materials such as new alloys and ultrapure
crystals has been around for years.
This work uses the separation of neuropeptides by nano-LC-MS to demonstrate that using freshly produced ultrapure
water as a solvent component in nano-LC-MS does not clog emitters.

The SYGEF[R] HP Gasket features an innovative self-centering design to resolve flange sealing problems in ultrapure
water (UPW) systems for ANSI, ISO/DIN or JIS pattern flange configurations.
To make pure and ultrapure
water for research laboratory applications, impurities that include particulates, colloids, ions, dissolved gases, dissolved organic solids, nucleases (RNase, Dnase) and pyrogens need to be efficiently and effectively removed.
