Abstract
In accordance with one or more embodiments of the present disclosure, a rotary evaporator is disclosed. The rotary evaporator may include a base, an evaporation vessel, a rotary union, a motor for rotating the evaporation vessel, a heat jacket, a purge tube and a purge system. The evaporation vessel includes a mounting end that is coupled to the rotary union and an opposite end, with an opening defined in the opposite end and a reservoir in communication with the opening for receiving a sample through the opening. The heat jacket heats or cools the sample when contained in the evaporation vessel, and the purge system controllably supplies fluid to the evaporation vessel via the purge tube.
Claims20
A rotary evaporator comprising:
- a base;
- an evaporation vessel having a mounting end and an opposite end, the evaporation vessel comprising an opening defined in the opposite end and a reservoir in communication with the opening for receiving a sample through the opening;
- a rotary union having a fixed section, a rotating section that is rotatably coupled to the fixed section, and internal conduits defined in the fixed section of the rotary union, wherein the fixed section extends along an axis and is fixedly coupled to the base, and wherein the rotating section is coupled to the mounting end of the evaporation vessel such that the rotating section of the rotary union and the evaporation vessel are rotatable about the axis relative to the fixed section of the rotary union and the base;
- a motor operable to cause rotation of the rotating section of the rotary union and the evaporation vessel about the axis;
- a heat jacket for heating or cooling the sample when contained in the evaporation vessel, the heat jacket comprising a hollow interior;
- a heat source in fluid communication with the hollow interior of the heat jacket, the heat source comprising a pump component operable to circulate a media through the heat jacket for heating or cooling the heat jacket, and wherein the media is configured to flow through the internal conduits defined in the fixed section of the rotary union;
- a purge tube at least partially extending into the reservoir of the evaporation vessel through the opening, such that a vapor channel is defined between an inner surface of the reservoir and an outer surface of the purge tube;
- and
- a purge system for controllably supplying fluid to the evaporation vessel via the purge tube, wherein the fluid comprises water vapor, gas, or a combination thereof.
A method of impregnating metal from a metal containing solution onto a catalyst support, the method comprising:
- loading the catalyst support in a reservoir of an evaporation vessel, wherein:
- the evaporation vessel comprises a mounting end, an opposite end that is opposite the mounting end, and an opening defined in the opposite end that is in communication with the reservoir and through which the catalyst support is loaded, and
- the mounting end of the evaporation vessel is coupled to a rotary union, the rotary union comprising a fixed section a rotating section that is rotatable relative to the fixed section, and internal conduits defined in the fixed section of the rotary union, with the fixed section extending along an axis and being fixedly coupled to a base, and with the rotating section being coupled to the mounting end of the evaporation vessel such that the rotating section of the rotary union and the evaporation vessel are rotatable together about the axis relative to the fixed section of the rotary union and the base;
- wetting the catalyst support with water vapor injected into the reservoir through a purge tube that at least partially extends into the reservoir of the evaporation vessel through the opening;
- transferring the metal containing solution onto the catalyst support contained in the evaporation vessel;
- rotating the evaporation vessel about the axis via a motor;
- supplying a media through the internal conduits of the fixed section of the rotary union to a hollow interior of a heat jacket via a pump component of a heat source that is in fluid communication with the hollow interior of the heat jacket, thereby heating the heat jacket;
- and
- heating the reservoir, via the heat jacket, to thereby evaporate liquid from the metal containing solution and thereby deposit the metal onto the catalyst support, wherein the heat jacket is operable to heat or cool the reservoir of the evaporation vessel.
