ZeptoMetrix - ANTYLIA Scientific products

Single-Element Standards for AA & ICP; Made with acid and ASTM Type I Water. Inorganic compounds and metals at 99.99% to 99.9999% purity (where commercially available). Directly traceable to NIST (where applicable). Accredited by A2LA to ISO/IEC 17025:2017 and ISO 17034:2016 AA & ICP Assurance Grade CRMs are designed for AA and ICP and are available in single and multi-element formulations. 70 elements are available as single-element standards and are available at 1,000 µg/mL and/or 10,000 µg/mL. They are packaged in 30 mL, 125 mL, 250 mL, and 500 mL bottles to minimize contamination. Custom standards can be manufactured upon request.

High Performance Liquid Chromatography (HPLC) is one of the most common instrumental techniques for analyzing mixtures of organic compounds in analytical labs around the world.  HPLC is a complex process that depends on each molecule’s ability to interact with the mobile phase that carries it through the column, the solid phase that fills the columns, as well as interactions between the different molecules in the sample.

This kit provides a rapid and accurate test to determine the presence of Aspergillus DNA in a sample. The kit uses quantitative PCR (qPCR) to measure the total amount of the four most common strains of Aspergillus: niger, fumigatus, flavus and terrus. Probes for the four strains of the Aspergillus are labeled with the FAM dye, and an internal control is labeled with HEX / VIC. The internal control ensures the sample is free of PCR inhibitors that would lead to false negative results. To help distinguish the Master Mix from the template DNA and from the final product during sample preparation, an inert yellow dye is provided to label the template prior to adding to the Master Mix which contains an inert blue dye. When mixed the resulting solution is green, confirming the presence of all components. The kit works with any qPCR system that supports the two color channels. It is very sensitive and can detect down to 10 copies of Aspergillus DNA.

One major source of contamination is the volumetric pipette. At SPEX CertiPrep, our chemists realized that they were spending valuable time manually washing and rinsing pipettes. Conventional washers were expensive and too large to comfortably fit in our laboratory. Our chemists designed a device that could be hooked up to a water line to allow the flow of water or other liquid through the inside and over the outside of the pipettes. As a result, our chemists spent less time cleaning pipettes, and more time manufacturing SPEX CertiPrep Certified Reference Materials (CRMs); used and trusted by labs all over the world.

Each aliquot contains 25 µg of DNA extracted from a partially purified preparation of Bacteriophage Lambda. The DNA was extracted from the phage following the whole blood spin protocol from the QIAamp® DNA Blood Maxi kit. DNA concentration and A260/280 ratios are determined using a NanoDrop ND-1000® . The extracted DNA also tested positive on an inhouse real time PCR assay. The preparation also contains Escherichia coli DNA
