Solvent removal from solutions is commonly performed in laboratory and production processes. There are a number of different methods that can be used for solvent removal, including evaporation, vacuum concentration, lyophilization, reverse extraction, solute precipitation, and dialysis (solvent exchange).

This Application Note will demonstrate the extraction of 1,4-Dioxane from an aqueous matrix using Option 1 of EPA Method 522 for 500 mL initial volume sample. It will make use of the SmartPrep Cartridge Extraction System to produce a valid Initial Demonstration of Precision (IDP) and Initial Demonstration of Accuracy (IDA).

Rotational viscometers are the most widely used tool in today's QC labs for making viscosity measurements.  Many small changes, like reduction in sample size and shortening the viscosity test time, can lead to significant increase in QC lab productivity.

The Cleveland Fire Department's mobile lab begins and ends with equipment.

Jason Todd is in the business of solving puzzles—in the laboratory. As a manager of the liquid chromatography lab and co manager of the gas chromatography lab at Polymer Solutions Incorporated (PSI) in Blacksburg, Virginia, he’s continually solving chemical and material mysteries.

Take a look at these white papers from BMG LABTECH and Molecular Devices.

Processing DNA samples can be a time consuming and expensive process. If degradation occurs during any of the steps, the process must start over. Before you begin, make sure that the DNA is free of RNA and protein contamination.

It has become crystal-clear to most of us that glass is something we just can’t live without. Scientists use glass beakers for measuring chemicals. We wear eyeglasses to improve our vision or to make a fashion statement.

Preclinical drug development relies on advanced in vitro models with a high degree of standardization to achieve maximal predictivity for an efficient compound de-risking strategy.

Although gold nanoparticle production can be controlled to yield specific size ranges, both the concentration and size of nanoparticles must be checked following production.

Analytical methods which extract aqueous samples require that the initial volume of the sample be determined, as it is necessary to calculate the concentration of the analytes in the sample.
