| Polishing Up On Water Quality C. Devaux, C. Monferran, M. Tarun, E. Riche, D. Darbouret Laboratory Equipment – Chromatography Techniques (2010) Dec. 2009 Abstract anzeigen Water plays a critical role in many analytical methods—particularly in the preparation of samples, standards, blanks, and eluents. It is crucial that water used for these applications does not introduce any impurities that could interfere with analytical results. As modern analytical instruments become capable of detecting ever increasingly low concentrations of analytes, ensuring the lowest level of background interference has become even more important—and more difficult. To meet this challenge, laboratory water purification systems have evolved accordingly. Current systems such as the Milli-Q Integral use a sophisticated combination of purification technologies to reduce ions, organics and other potentially background-causing contaminants to extremely low levels (i.e., 18.2 MΩ.cm resistivity and <5 µg/mL of TOC).

| Endotoxin-Free Water for Tissue Culture E. Riché, J. Bôle and S. Mabic Lab Manager Magazine (2010) May 2009 Abstract anzeigen Water is a ubiquitous solvent used throughout cell isolation and culture. Therefore, water contamination may affect experimental outcomes. The use of ultrapure water is advisable for culturing of cells sensitive to environmental contaminants, such as endotoxins and bacteria. Cardiomycyte isolation experiments showed that using water contaminated with bacteria and endotoxins decreases cell viability, while using freshly produced ultrapure water dramatically increases it. Additionally, an ultrafiltration cartridge will efficiently remove large molecules that may be present in water. Volltextartikel | |
| Water quality in patient testing J. Long and S. Mabic Clinical Lab Products (2007) April, 22-23 2007 Abstract anzeigen Sophisticated diagnostic equipment is designed to improve quality, increase throughput, and manage continued labor shortages. All diagnostic manufacturers can provide the end user with software specifications that simplify automatic sampling and predilution; ensure workflow efficiency with high-speed throughput and performance; provide accuracy in testing with precision optical systems; deliver real-time access and alerts for patient and QC packages; and offer mechanical alerts to any possible instrumentation failures. Additionally, troubleshooting instrumentation, even with the above solution, creates unique challenges for medical technologists. Instrumentation can alert, flag, and warn that something is problematic, but it takes an experienced medical technologist to determine the root cause. One parameter, even though utilized by each end user on any kind of diagnostic instrument, has not been considered: water. Used in a variety of assays, water is a major reagent in clinical chemistry and immunoassay testing. Analytical factors linked to water quality need to be controlled and optimized to reduce the number of test failures. The water quality delivered to the analyzer is as important as any other reagent. Control of bacteria and its by-products with Elix technology and Biopak filters provides the highest quality water to be used in assays sensitive to these contaminants. Control of the water quality eliminates frequent decontamination. This optimizes analyzer performance and reduces downtime that can be costly to the customer and analyzer manufacturer. | Water quality in patient testing

| Increased Flexibility in the Delivery of Ultrapure Water S. Mabic, D. Darbouret and J.F. Pilette Nature Methods (2006) 3 v-vi 2005 Abstract anzeigen The Milli-Q Advantage system offers flexibility in the quality and delivery of various ultrapure water grades in laboratories. A single purification unit can be connected to up to three point-of-use dispensers, which can be equipped with different purifiers to provide the necessary water quality for various applications. The management of diverse and specific needs within the laboratory has been a driving force in developing this unique water purification system. This combination of technologies provides high-quality water with low TOC and high resistivity. Finally, this breadth of point-of-use purifiers addresses emerging needs as well as those for existing applications. Volltextartikel | |
| Optimized POU device for the removal of RNases and endotoxins in high purity water Mabic, Stephane, Daniel Darbouret, and Ichiro Kano Ultrapure Water, March 2003: 53-59 2003 Abstract anzeigen Performances of a disposable point-of-use (POU) UF device are described here, in terms of endotoxin and RNase removal. Following a brief description of technical features and data on extractables, the efficiency of the UF on endotoxin and RNase removal is illustrated with a number of typical experiments. |

Der Biopak® Endfilter wird an der Entnahmestelle von Wasseraufbereitungssystemen wie den POD-Entnahmeeinheiten von Milli-Q® Systemen installiert. Die Leistung des Filters wird für eine Dauer von bis zu drei Monaten garantiert. Der Ultrafilter besteht aus Polysulfon-Hohlfasern, deren Struktur eine optimale Rückhaltung der spezifischen Verunreinigungen bei gleich bleibend hoher Fließrate und minimaler Abgabe ionischer und organischer Substanzen garantiert.
Pyrogenfreies und bakterienfreies Laborwasser
Pyrogene beeinflussen Zellkulturen und biochemische Experimente bekanntlich in vielerlei Hinsicht. Die geläufigsten Pyrogene von Bakterien sind Endotoxine (LPS - Lipopolysaccharide). In Reinstwasser bilden die LPS-Untereinheiten Strukturen mit hohem Molekulargewicht, die durch Ultrafiltrationsmembranen effizient entfernt werden können. Experimente haben gezeigt, dass der Biopak® Endfilter mindestens 90 Tage* lang zur Aufbereitung von Reinstwasser eingesetzt werden kann und Produktwasser mit einem Pyrogengehalt unter 0,001 EU/ml zur Verfügung stellt.
Nukleasefreies Wasser
Molekularbiologen benötigen nukleasefreie Reagenzien, da Nukleinsäuremoleküle im Mittelpunkt ihrer Forschung stehen. Die Biopak® Ultrafiltrationsmembran hat sich als eine effektive und praktische Lösung für diese Wissenschaftler erwiesen. Im Gegensatz zur Verwendung von DEPC (Diethylpyrocarbonat) ist die Ultrafiltration einfach in der Handhabung, erfordert keine lange Behandlungsdauer und verursacht keine Kontamination des behandelten Wassers durch CO2 und Ethanol. In Beaufschlagungstests wurde die Effizienz des Biopak® Endfilters bei der Abscheidung von RNasen (< 1 pg/ml) und DNasen (< 5 pg/ml) validiert. Jeder Biopak® Filter wird mit einem Qualitätszertifikat geliefert.
