  • Standards and Reagents

    Friday, June 05, 2015
    Standards and reagents are available to researchers with certain assurances as to composition, purity and performance. Read More

  • A Micro Look at Microplates

    Monday, May 11, 2015
    Microplates, also known as microwell plates, are widely used in molecular biology, clinical and analytical workflows. Multiwell microplates are a staple for performing enzyme-linked immunosorbent assays (ELISAs). Read More

  • GC/MS Technology: Improving Sensitivity and Results

    Monday, May 11, 2015
    Gas chromatography/mass spectrometry (GC/MS) is a highly selective analytical technique for identifying compounds using mass detection. As in liquid chromatography (LC), gas chromatography relies on a mobile phase, but in GC, the mobile phase is a ... Read More

  • Beyond Light: Characterizing the Molecular World With Scanning Electron Microscopes

    Friday, April 10, 2015
    Centuries ago, glass lenses were employed to visually enhance small objects beyond the physical abilityBof the human eye. Light and compound mi- croscopes led to the birth of microbiology. However, the physical properties of visible light greatly ... Read More

  • Shaking Cells to Produce Novel Products

    Friday, April 10, 2015
    “Biotechnology” is a term that has only been used for a few decades. However, the fundamentals of biotechnology, including the concepts of shaking, heating or cooling a fermenting mixture, actually have been used for thousands of years. Read More

  • Cryoware: Essential Tools for Cryopreservation

    Friday, February 27, 2015
    Cryopreservation is the process of freezing cell cultures and storing them at extremely low temperatures. During that process, cultured cells are mixed with a cryo-protective solution and added to labeled storage vials, which are then cooled to ... Read More

  • Ultralow-Temperature Freezers: Antarctica in a Box

    Wednesday, February 25, 2015
    In most common parlance, ultralow-temperature freezers (ULT freezers) are containers capable of maintaining an interior temperature of about –80 °C, typically by mechanical means. While they come in different orientations and sizes, they are most ... Read More

  • Spectrofluorometers: Tools for Measuring Fluorescence Signature

    Friday, January 30, 2015
    Spectrofluorometers (or fluorescence spectrophotometers) measure the fluorescence signature of an analyte in a sample based on its specific excitation and emission wavelengths. The fluorescence signature can be correlated to the concentration level ... Read More

  • Product Intelligence: Mighty Readers for Microplates

    Monday, January 26, 2015
    The microplate reader is an essential tool for analyzing assays in many, if not most, life sciences laboratories. Yet like fruit, which can be anything from banana to tomato to compote, a microplate reader can be any instrument capable of accepting ... Read More

  • DNA Sequencers: Cracking the Genomic Code

    Friday, October 24, 2014
    DNA sequencers automate the determination of the precise order of nucleotide bases—adenine, guanine,cytosine, and thymine—in a DNA region of interest. The order of the DNA bases is reported as a text string, called a read. Read More

  • PCR Enclosures: Essential for Improving PCR Accuracy

    Friday, October 24, 2014
    PCR enclosures are designed to provide effective decontamination of solutions, reagents, and equipment before and during polymerase chain reaction (PCR) manipulations in order to improve their accuracy. PCR enclosures, which include PCR workstations... Read More

  • Detecting and Managing Water Contaminants in the Laboratory

    Thursday, October 16, 2014
    Water purity is a fundamentally important factor in many laboratories, yet it is frequently overlooked. Researchers use water in most lab processes, and poor water quality can quickly lead to mounting problems, resulting in the generation of ... Read More

  • LC Columns: Pillars of Sample Purification and Analysis

    Monday, September 22, 2014
    Liquid chromatography columns, or LC columns, have been used in the food, chemical, petrochemical, and pharmaceutical industries and forensic, clinical, and medical determinations for sample purification and analysis. In an LC column, the sample ... Read More
