NYLON LOW EXTRACTABLES (LE) • Superior to Nylon 66 membranes • Nylon-LE is a unique unsupported Nylon membrane • Does not release significant levels of extractables when in contact with acetonitrile • Suitable for use with any HPLC sample or solvent • The elimination of the polyester support in these Q-Fil filters, combined with the unique surface characteristics of this new membrane, eliminates many of the extractables found in Nylon membranes and results in a much cleaner filtrate
The Q-Fil range of Certified Syringe Filters set the new Quality standard for today’s laboratory syringe filters. Manufactured from the highest quality medical grade high density polypropylene Q-Fil Certified Syringe Filters provide excellent chemical compatibility with acids, alcohols, bases, ethers, glycols, ketones and oils, with maximum operating temperatures of 135°C. Every colour-coded filter is printed with the individual batch number, details of the membrane material and its pore size, on the outside rim of the filter, making them unique for traceability, GLPs and validation purposes. Q-Fil Certified Syringe Filters - • Manufactured in compliance with ISO 9001:2000 quality procedures. • Are supplied with a Certificate of Analysis and Conformance to guarantee its batch to batch quality and performance. • Are available in the most popular sizes, porosities and membrane types. • Provide excellent resistance to all routinely used HPLC solvents. • Have filter housings manufactured from high density medical grade polypropylene. • Contain extremely low level of extractables for highly sensitive work. • Luer connections fully comply with ISO 594-1. • Filters are available with standard and 'Slim Tip' sized outlets.

‘Smelling’ Prostate Cancer A research team from the University of Liverpool and the University of the West of England (UWE Bristol) has reached an important milestone towards creating a urine diagnostic test for prostate cancer that could mean that invasive diagnostic procedures that men currently undergo eventually become a thing of the past.Charting Kidney Cancer Metabolism Changes in cell metabolism are increasingly recognized as an important way tumors develop and progress, yet these changes are hard to measure and interpret. A new tool designed by MSK scientists allows users to identify metabolic changes in kidney cancer tumors that may one day be targets for therapy.Portable Kit Can Recover Traces of Chemical Evidence A chemist at the National Institute of Standards and Technology (NIST) has developed a portable version of his method for recovering trace chemicals such as environmental pollutants and forensic evidence including secret graves and arson fire debris.Diagnosis of Two Rare Childhood Diseases Improved For the first time, researchers have developed tests that could improve the diagnosis of two rare childhood diseases known as congenital disorders of glycosylation (CDGs) and metachromatic leukodystrophy, and that could even lead to new treatments for CDGs. Artemisinin Mechanism Uncovered New understanding of how artemisinin works could facilitate development of new drugs and therapeutic strategies against malaria.Cleaning Out the Membrane Each Day Cell membranes are made up of a lipid bilayer that is constantly changing due to the flux of material in and out of the cell. AMRI Acquires Whitehouse Laboratories Strategically extends AMRI's analytical offerings in rapidly expanding area of outsourcing services.Novel Approach to Understanding Brain Function Russell Poldrack scanned his brain to create the most detailed map of brain connectivity ever. New Analysis Technique for Chiral Activity in Molecules Professor Hyunwoo Kim of the Chemistry Department and his research team have developed a technique that can easily analyze the optical activity of charged compounds by using nuclear magnetic resonance (NMR) spectroscopy. High Throughput Mass Spectrometry-Based Screening Assay Trends Dr John Comley provides an insight into HT MS-based screening with a focus on future user requirements and preferences.
