PURPOSE:To perform automatically evaporation in a short time without the possibility of bumping by decreasing automatically the number of revolution of a motor which rotates a flask from the set values relating to the initial number of revolutions of said motor, the final number of revolutions just...
1. the act of rotating; rotary motion 2. a regular cycle of events in a set order or sequence 3. (Agriculture) a planned sequence of cropping according to which the crops grown in successive seasons on the same land are varied so as to make a balanced demand on its resources of fertil...
or purum and used as received. Technical solvents were distilled before use for column chromatography and extraction on a rotary evaporator (Heidolph Hei VAP Value, vacuubrand CVC 3000). Reactions were monitored on Merck Silica 60 F254 TLC plates. Detection was done by irradiation with UV light...
Further, E3.3 shows the schematic diagram of the proposed algae drying based on heat circulation technology with steam recirculation. The steam exhausted from the main evaporator (HX3) is split into purged and recirculated steam (S12). The amount of the purged steam is equivalent to the water...
Technical solvents were distilled before use for column chroma- tography and extraction on a rotary evaporator (Hei-VAP Value). Thin-layer chromatography (TLC) was conducted on Merck Silica 60 F254 TLC plates and visualization conducted with a ultraviolet lamp (254 or 366 nm). Deuterated sol-...

A rotary evaporator consists of a round flask in a bath of hot water that is designed to evaporate solvents. The flask is rotated and the solvent collects under a vacuum onto a condenser and drips into a condensate collecting flask. in this way solutions can be concentrated or purified. By...
The deflecting effect of the earth's rotation on winds has been known since the writings of Hadley in 1735, and observations of the clockwise diurnal directional turning of the sea and land breezes in the Northern Hemisphere have been pu... Neumann,J. - 《Bulletin of the American Meteorologic...
