A rotary evaporator (or rotavap /rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.When referenced in the chemistry research literature, description of the use of this technique and equipment may include the phrase "rotary evaporator", though use is often rather signaled by other language (e.g., "the sample was .
A typical thin film evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent .

Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporator. The liquid flows as a thin film on the inside of heated vertical tubes, driv-en by gravity. The resulting vapor normally flows cocurrently with the liquid, in the centre of the tubes. A full evaporation stage consists of the
The R-300 meets the highest expectations in convenience and versatility. Its modular design allows extension of the Rotavapor® R-300 to a fully integrated system where a central interface regulates .
The RotoVap Limitations. For years, the industry standard for solvent recovery has been the rotary evaporator, or otherwise known as the RotoVap. A generic 20L RotoVap has a recovery rate of about 1.5 gallons per hour. For small scale setups this may suffice, but large-scale manufacturers have been forced to run multiple RotoVaps.
Dec 15, 2012 · Still checking specs and prices for the gear motor and trying to decide on the incremental utility of a variable speed gear motor, vis a vis fixed ~2 rpm unit, giving the drum about 1.6 sq/ft of thin film evaporative surface per minute under vacuum, per drum. I may jury rig the first unit with a variable speed motor, to determine optimum speed.

First wiped film evaporation stage: degassing. Degassing involves removal of volatiles and gas with heat while stirring. Typical ethanol removal is 80-90% using a rotovap or falling film evaporator, degassing using a wiped film evaporator achieves >98% ethanol removal which is required for wiped film .
A typical thin film evaporator has a water bath that can be heated in either a metal container or crystallization dish. This keeps the solvent from freezing during the evaporation process. The solvent is removed under vacuum, is trapped by a condenser, and is .

30L Vacuum Distillation/Rotovap with heater water bath for vacuum distillation. . The rotating flask continuously covers a large surface area with a thin film which is ideal for rapid heat transfer. Fortuitously, the thin film also ensures uniform heat distribution without local heating. . 10L: 10L: 20L: Stirring Speed（RPM) 0-120 .
What are the evaporation modes of vacuum rotary . - Rotovap. Detail of rotary evaporator. Thin film is also a kind of the evaporator .It is a method of forcing film formation by rotating the scraper to evaporate which has the advantage of high heat transfer coefficient,high evaporation intensity,short flow time and large operating flexibility,especially suitable for high viscosity material .
A thin film improves mass transfer and speeds evaporation while a vacuum is used to decrease the boiling point of the target solvent. The key difference between a rotovap and a thin film is in how that film is created and how much throughput can be produced.
