A key disadvantage in rotary evaporations, besides its single sample nature, is the potential of some sample types to bump, e. This page was last edited on 18 Novemberat Zhengzhou Rotarry Instrument Equipment Co.
Xi’an Tefic Biotech Co. It is effective for evaporating samples abhorrent of contamination such as samples for analytical process. Labfirst Scientific Instruments Shanghai Evaporatr. Can be connected to the newly developed vacuum controller NVC to realize most appropriate vacuum pressure control fit for a sample. Henan Lanphan Industry Co. Both NS and NV have manual slide mechanism in addition to jack mechanism.
Liquid solvents can be removed without excessive heating of what are often complex and sensitive solvent-solute combinations. The vacuum system used with rotary evaporators can be as simple as a water aspirator with a trap immersed in a cold bath for non-toxic solventsor as complex as a regulated mechanical vacuum pump with refrigerated trap. When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase rptary evaporator”, though use is often rather signaled by other language e.
Henan Touch Science Rotaey Co. It is hard to break and prevents glass and solvent dispersion even in case of glass projection.

Views Read Edit View history. Both NA and NB have a manual slide mechanism in addition to the jack mechanism. Users of rotary evaporation equipment must take precautions to avoid contact with rotating parts, particularly entanglement of loose clothing, hair, or necklaces.
Vacuum evaporators as a class function because lowering the pressure above a bulk liquid lowers the boiling points of the component liquids in it. In particular, bumping can often be prevented by taking homogeneous phases into the evaporation, by carefully regulating the strength of the vacuum or the bath temperature to provide for an even rate of evaporation, or, in rare cases, through use of added eeyela such as boiling chips to make the nucleation step of evaporation more uniform.
However, careful application also allows removal of a solvent from a sample containing a liquid compound if there is minimal co-evaporation azeotropic behaviorand a sufficient difference in boiling points at the chosen temperature and reduced pressure.
Rotary evaporators are also used in molecular cooking for the preparation of distillates and extracts. Rotary evaporators ,Jacketed glass reactors,Single-layer glass reactors,Vacuum drying ovens,Blast drying ovens. Labfreez Instruments Hunan Co.

EYELA 1L Rotary Evaporator, NV
Vacuum controller with excellent control functions. Rotary evaporation for high boiling hydrogen bond-forming solvents such as water is often a last recourse, as other evaporation methods or freeze-drying lyophilization are available.
