  • Temperature Chambers and Environmental Test Chambers

    Monday, April 20, 2009
    The best way to understand how a product or material will perform in the field or over time is to use a laboratory test chamber to model those conditions. This is done in one of two ways: the test chamber may model the conditions exactly as they are,... Read More

  • Do Your Work Cleanly With Gloveboxes

    Thursday, February 02, 2012
    Gloveboxes are used in laboratories across the sciences. This article will focus on the use of gloveboxes in the life sciences—especially in those laboratories housed in academic institutions, government institutions, biotechnology companies, and ... Read More

  • Guide to Purchasing a Rotary or Nitrogen Evaporator

    Thursday, September 06, 2012

  • Mercury Analyzers in the Laboratory

    Wednesday, March 20, 2013
    Mercury is a toxic element, harmful to the environment and poisonous to humans, even at very low levels. It is generated by industry, by burning fossil fuels and as a by-product of some bacteria. Read More

  • Spectrophotometers Overview

    Tuesday, April 23, 2013
    Spectrophotometers measure the amount of light of a specific wavelength that is absorbed by a sample. A spectrophotometer is used chiefly to measure the concentration of analytes in solutions, but is also used to characterize liquid and solid ... Read More

  • Portable XRF: Nondestructive Testing in Seconds

    Monday, July 01, 2013
    We are all familiar with X-rays, the short, highly energetic waves used by dentists to check for cavities, and by airport screeners to look for contraband. We experience fluorescence—the phenomenon by which something absorbs energy and in turn ... Read More

  • UHPLC: Pushing the Limits of HPLC

    Friday, August 09, 2013
    For fields that rely on liquid chromatography, the standard today is usually ultra high-performance liquid chromatography (UHPLC). And with good reason—compared to its chromatography predecessors, UHPLC is faster, provides better separation, and... Read More

  • Particle Sizing Systems: Key to QC and Product Testing

    Thursday, September 05, 2013
    A particle size analyzer, also known as a particle sizer, is used to measure the sizes of particles in a sample. It can also determine distributions of particle sizes. Read More

  • Blood-Alcohol Analysis by HS-GC Using 0.15-i.d. Columns

    Friday, September 27, 2013
    Forensic laboratories face the need to analyze many samples of human blood and body fluids for alcohol content. The most important compound in blood-alcohol (BAC) analysis is ethanol, but the detection of several other significant alcohols and their ... Read More

  • Differential Scanning Calorimetry—A Fundamental Thermal Analysis Tool

    Thursday, October 24, 2013
    A differential scanning calorimeter (DSC) is a benchtop instrument used to determine thermodynamic transitions and heat capacities of a variety of substances. A small sample—typically 5–20 mg, around the size of the tip of a #2 pencil—is placed in ... Read More
