Prior Scientific has published a new 12-page catalogue that brings together its range of high performance LED and metal halide light sources proven to provide the best possible illumination for your microscopy work.

Lab glassware washers offer an excellent solution for laboratories that need to clean dirty labware including beakers, test tubes, Erlenmeyer flasks, cylinders, and BOD bottles. Technicians may be unsure whether dirty plasticware can also be cleaned in a glassware washer, leading them to hand wash the equipment which can be extremely time consuming. Lisa Choplo, Application Specialist at Miele Professional, addresses the most common concerns users have about cleaning plastics in a glassware washer.

Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences, announces the publication of a new sample preparation guide and selection tool to help scientists produce cleaner samples for more efficient chromatographic analysis.

Genevac, a world leader in solvent removal technologies, has released a new 24-page guide ‘Introduction to Evaporation.’

Abstract: Persistent organic pollutants (POPs) can cause long term damage to the environment. Two classes of organic molecules have come to the attention of regulators and water treatment authorities in recent years; iodinated X-Ray contrast media (XCM) and artificial sweeteners (AS). These molecules, by design, have a high degree of stability. Aware of the increased abundance of these molecules in waste water, the IWB Water Laboratory set out to develop a robust, simple method to analyse levels of these molecules in water from the river Rhine, ground water and drinking water.

A problem that has gone relatively unnoticed when achieving reliable measurements is that of transpiration. Transpiration is defined as the passage of vapor from within a container to the outside. Transpiration is a systematic error that increases the concentration of a solution as time passes.
