Provided herein are integrated distillation apparatuses configured as stand-alone fully integrated systems having a reduced footprint. Integrated distillation apparatuses can have a rotary evaporator, a condenser, and an integrated refrigeration system or chiller, as well as an integrated water bath and vacuum pump, all of which can be integrated into a central frame and/or housing assembly. Integrated distillation apparatuses can be configured such that the rotary evaporator is movably attached to a frame structure and configured to be vertically translatable in position, whereas the condenser can be affixed to the structure by an arm extending from the structure and adjacent to the rotary evaporator, and wherein the refrigeration system can be in fluid communication with the condenser.

Herein, a cleaning device for a rotary evaporator (2) is provided. The rotary evaporator (2) comprises at least a rotatably arranged rotary flask (4) for receiving a substance to be evaporated and a condenser (5) for condensing the evaporated substance during operation of the rotary evaporator (2). The cleaning device (1) comprises at least a supply line (16, 16′) for supplying a cleaning agent, a cleaning agent supply (13) for storing the cleaning agent and a pressure generating means (15) for generating a pressure in the cleaning agent in order to supply a pressurized cleaning agent from the cleaning agent supply (13) through the supply line (16, 16′) to the rotary flask (4) and/or to the condenser (5).

A catalyst-free electrochemical deuteration method using deuterium oxide as a deuterium source, adding an electrolyte, an organic compound containing an ethylenic bond or acetylenic bond, deuterium oxide, and an organic solvent into a reactor, applying a direct current voltage of 4-8 V between electrodes of a carbon felt in an atmosphere of an inert gas for an electrolytic reaction, to obtain a product, and purifying the product to obtain a deuterated product. In the method provided by the present disclosure, with the organic compound containing an ethylenic bond or acetylenic bond as a raw material, deuterium oxide as a deuterium source, cheap and readily available carbon electrode materials as cathodes and anodes, it is possible to obtain deuterated products by a direct current electrolysis in an organic solvent, without any transition metal catalysts.

Disclosed is a removable containment device for a rotary evaporator, comprising: a first end (12) for sealed connection to a rotation shaft (3) of the rotary evaporator (1); a second end (13) for sealed connection to a container (2) for receiving a mixture to be evaporated; and a body (11) in fluid connection with the first and second sealed connection ends (12, 13) comprising a valve system (14) for the selective passage between the first and second ends (12, 13) of the evaporating constituent of the mixture to be evaporated.

A rotary evaporator for accurately and quantitatively recovering multiple solvents or concentrating multiple samples at once is provided. At least two distillation flasks are included. The distillation flasks are connected in sequence and rotated along the same axis. A bracket is disposed at the lower part between the distillation flasks for support. Instead of one rotation axis, at least two axes are included. Each rotation axis is provided with at least one distillation flask. The number of condensers and the number of collecting flasks increase correspondingly with the number of distillation flasks. If the number of distillation flasks on one rotation axis is greater than 1, a connector is disposed between the condenser and a transmitter. The collecting flask can be changed into a collector with the function of accurately quantitating and discharging distillates. Each distillation flask may be connected to a concentrated liquid quantitative assembly.

A laboratory device, in particular a rotary evaporator, serves for evaporating a substance, preferably under reduced pressure, and comprises an evaporation flask for receiving the substance to be evaporated, a condenser for condensing the evaporated substance and a vapor passage for passing through the evaporated substance, which vapor passage is arranged in a vapor path between the evaporation flask and the condenser. The laboratory device further comprises a detection unit for foam detection, which detection unit is provided outside of the vapor passage and/or the evaporation flask.

Methods and apparatus consistent with the present disclosure may provide electrical energy and thermal to extraction or separation equipment. Methods and apparatus consistent with the present disclosure may extract and concentrate essential elements plant matter. An amount of wasted heat energy collected from a engine that powers an electrical generator may be provided to an evaporation or separation process when electrical power is provided to extraction or separation processing equipment. Computers or electronics that control equipment consistent with the present disclosure may be remotely controlled via a mobile electronic device, when desired. Such computers or electronics may receive sensor data related to the operation of plat matter extractors, related separation equipment, or other equipment may be used to manage a production line. As such, methods and apparatus consistent with the present disclosure may extract essential elements from cannabis plant matter and process those essential elements into cannabis extracts or isolates.

The present invention provides a rotary evaporator capable of accurately quantifying concentrated liquid and/or distillate. A distillation flask is improved into a structure having a liquid discharge opening formed at the bottom, and/or a spherical collecting flask is improved into a structure having a liquid release opening formed at the bottom. Concentrated liquid and/or distillate can be discharged without dismounting the distillation flask and/or the collecting flask. In addition, fine metering scale tubes and quantitative capacity increase units are disposed at the liquid discharge opening and/or the liquid release opening, there is a valve on the top and another valve on the bottom of each tube, so that the constant subtle changes of the amount of concentrated liquid and/or distillate can be observed, and an accurate amount of concentrated liquid and/or distillate can be discharged.
