RayKol Auto EVA 12 is a nitrogen blow-down automated evaporation system that provides automated evaporation of up to 12 samples in parallel with endpoint detection. This automated nitrogen evaporation system uses vortex airflow generated from stable angled nitrogen blow, to constantly disturb the sample surface and lower its vapor pressure in order to gain gently rapid evaporation under water bath heating. Each sample position is equipped with optical sensor to precisely determine endpoint of concentration. User can have real-time monitoring to whole process through built-in touch screen, make it easier to access and observe.

When it comes to sample preparation, it is crucial to remove any excess solvent from the sample while preserving its integrity. Nitrogen evaporators are one of the most popular tools used for this purpose. Nitrogen evaporators use the principle of evaporation to remove excess solvents from samples. In this article, we will discuss the principle and application of nitrogen evaporators in sample preparation.

concrete water tank roof and covers are critical components of storage tanks designed to protect the stored media from the elements while ensuring safe operation. Roofs and covers play a vital role in preventing evaporation and reducing product contamination.

In the preceding article, we discussed the application of hot-melt extrusion technology in developing amorphous solid dispersions (ASD) for pharmaceutical formulations. The process involves dispersing a solution through a spray dryer, where it meets hot gas, quickly evaporates, and forms amorphous solids. Spray drying techniques are extensively employed in developing formulations for drugs with low solubility, largely due to their well-established scalability from small-scale experiments to large-scale commercial production, aligning with Good Manufacturing Practice (GMP) standards. Table 1 in the article provides examples of various drugs that have been commercially produced using spray drying technology to prepare amorphous solid dispersions.
