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.

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.

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.

The effectiveness of sample preparation influences not only the quality and quantity of the results, but also the conclusions drawn from experiments.

Today, newer purification technologies have proven able to compete with long-established distillation. Following a brief review of these purification technologies are data for performances of a single and double distillation system, and the Millipore Elix UV system.

Ergonomic injuries are widely recognized as a major factor in work place health. About one-third of all occupational injuries and illnesses stem from over exertion and/or repetitive motion.
