In this application note, discover a new sensitive technique for fingerprint examination allowing forensic scientists to gain more information - such as visualizing hidden fingerprints left on challenging surfaces or analyzing the chemicals in residues.

After a skin injury, our body normally triggers a complex wound healing process to repair the damage. Scientists are investigating the use of tissue engineering to mimic the body’s natural processes and help promote the healing of chronic wounds. In a recent study published in Carbohydrate Polymers, scientists create porous 3D scaffolds made of a naturally-occurring polysaccharide derived from crustacean shells and demonstrate their wound-healing potential.

Every day, scientists around the world are using water for a multitude of purposes. But the quality of this reagent is too important to ignore - contaminants and variabilities in laboratory water are putting too many results at risk. This guide shares ELGA’s expert knowledge about laboratory water and water purification technologies. Different levels of water purity are explored and some of the challenges around choosing what to use for a successful experimental outcome at the most economical cost are examined.

Until recently, bisphenol A (BPA) was widely used in the manufacture of polycarbonate plastics and epoxy resins, and the risks associated with BPA remain highly controversial. As a result, numerous determinations of trace BPA are now carried out, creating the need for robust analytical processes. In this application note read how high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) offers extremely high sensitivity for BPA detection and how ELGA® pure water systems offer effective removal of BPA.

The aim of the study presented in this poster was to outline the limitations of conventional single cartridge ion exchange resin cartridges and the limitations of in-line resistivity monitoring. The second goal was to determine the benefits of twin resin-bed cartridges with multi-stage resistivity monitoring in ultrapure water purification systems.

This application note shows that the use of Type I ultrapure water to effectively eliminate the presence of biologically active species and other contaminants which could interfere with the culturing process is essential. It also shows that general laboratory grade purified water (Type II) with low levels of bacterial and organic contamination is usually sufficiently pure for bacterial cell culture.

This application note describes a method of achieving consistent, reliable electrophoresis. A key requirement for electrophoresis is the use of water that does not contain any significant levels of biologically active molecules such as endotoxins, nucleases and proteases. Apyrogenic Type I ultrapure water is designed for use in enhancing electrophoresis. This note includes the importance of purifying water for eletrophoresis, and a section on Ultraviolet (UV) radiation.

It is highly likely that water is the most commonly used solvent in your laboratory, thus it is important to ensure its quality is sufficient for your work. Watch this video to discover the PURELAB Chorus, the latest innovation from ELGA that will be showcased at Pittcon 2013.

This poster presentation shows how optimizing ion exchange technology can ensure consistent, impurity free water for the lab. Jim Keary, ELGA Labwater, outlines the advantages of a twin cartridge ion exchange system and clearly illustrates this with the use of two studies. Interview filmed by SelectScience at Pittcon 2012.
