| Polishing Up On Water Quality C. Devaux, C. Monferran, M. Tarun, E. Riche, D. Darbouret Laboratory Equipment – Chromatography Techniques (2010) Dec. 2009 Mostra il sommario 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 Mostra il sommario 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. Testo completo dell'articolo | |
| Water quality in patient testing J. Long and S. Mabic Clinical Lab Products (2007) April, 22-23 2007 Mostra il sommario 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 Mostra il sommario 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. Testo completo dell'articolo | |
| 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 Mostra il sommario 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. |

Le cartucce per il trattamento finale Biopak® sono state ideate per l’installazione sull'uscita di sistemi di purificazione dell'acqua quali le unità POD dei sistemi Milli-Q®. Sono garantite per un periodo massimo di tre mesi. Questi ultrafiltri sono costituiti da fibre cave in polisulfone la cui struttura è stata ottimizzata per un'efficiente reiezione dei contaminanti indesiderati, senza dover rinunciare a portate elevate e minimizzando il rilascio di sostanze ioniche ed organiche
Acqua apirogena ed esente da batteri
È noto che i pirogeni possono interferire con gli esperimenti di colture cellulari e di biochimica in molti modi. I pirogeni di origine batterica più comuni sono le endotossine (lipopolisaccaridi ‒ LPS). Nell’acqua ultrapura, le subunità dei LPS si aggregano a formare strutture ad alto peso molecolare che possono essere efficientemente rimosse dalle membrane da ultrafiltrazione. Prove sperimentali hanno convalidato che le cartucce Biopak® possono essere utilizzate per purificare l'acqua ultrapura ed ottenere livelli di pirogeni inferiori a 0,001 EU/mL. per almeno 90 giorni*
Acqua esente da nucleasi
I biologi molecolari necessitano sistematicamente di reagenti esenti da nucleasi perché le molecole degli acidi nucleici sono il cuore delle loro ricerche. Per loro, l'ultrafiltrazione Biopak® si è dimostrata una soluzione pratica ed efficace. Al contrario del DEPC (dietilpirocarbonato), l'ultrafiltrazione non implica la manipolazione di sostanze pericolose, né trattamenti di lunga durata e neppure una contaminazione dell'acqua trattata con CO2 ed etanolo. Test di challenge hanno convalidato l'efficienza delle cartucce Biopak® nella rimozione di RNasi (< 1 pg/ml) e DNasi (< 5 pg/ml). Ogni ultrafiltro Biopak® è fornito completo di Certificato di Qualità.
