Concentrate biological samples quickly and safely

GENEVAC outlines the significant operational benefits that can be found when its miVac sample concentrator is used instead of a ‘blowdown’ evaporation system.   Blowdown evaporators remove solvent (as their name suggests) by blowing inert gas into open sample vessels. They…

Rocket beats rotary when evaporating natural products

GENEVAC has launched a new website to expound the benefits of its Rocket high speed evaporation system over alternative rotary evaporators when drying natural product extractions. Rotary evaporators have commonly been used for this operation, but Genevac says the result…

Evaporator protects samples and increases productivity

GENEVAC’s HT Series II evaporators are equipped with the company’s proprietary SampleGuard temperature control technology to automatically detect when samples are dry, initiating the shutdown of evaporation and thereby protecting valuable samples from potential thermal degradation. Combined with the company’s…

Drying of aqueous HPLC fractions made faster and easier

A HIGH throughput method for drying high performance liquid chromatography (HPLC) fractions containing water is described in a new white paper from Genevac. Many lab workers experience difficulty in drying HPLC purification fractions. While the more volatile acetonitrile and methanol…

Evaporators optimised for environmental research

MONITORING substances that are potentially harmful to health is a core activity for many organisations, including government agencies and private firms checking they are not harming their staff or the environment. Atmospheric, water, soil, and vegetable samples are routinely monitored…

How to evaporate solvents from DNA and other specimens

THE REMOVAL of water and organic solvents from samples of DNA, RNA, and other biological specimens is a slightly more delicate task than the average laboratory evaporation procedure. Samples are typically of low volume and are heat-sensitive, and so may…

Solving the solvent bumping problem

LABORATORY scientists, especially those working in purification and synthesis, may find advantages in using the Dri-Pure system which facilitates solvent removal without cross-contamination or sample loss due to bumping. Genevac says that other methods of removing solvent are difficult and…

Enhanced lyophilisation with this condenser

GENEVAC promises a new benchmark for enhanced evaporation and lyophilisation with its new SuperCool 75 condenser, when used in conjunction with the HT-12 high throughput evaporator. Preparing dried powder samples from HPLC purification fractions is a routine laboratory task, and…
