dClaims. (o1. 219--38)= This invention relates to an apparatus to be used in rapid evaporation of solutions, the ob-' jectbeing to hasten the evaporation without the loss of salts or solid matter.
For this purpose the invention provides a means for setting a metal disc, with proper lugs on the underside, the said lugs are placed on top of the evaporating dish or container to be used in the process of evaporation.
With the above and other objects inview,the i invention further includes the followingnovel 1 features in'detail of construction, to behereinafter more fully described, and illustrated in' accompanying drawings and pointed out'in ap-.
"Tpended claims.
The principal object'of this invention is to place the Bunsen gas flame, or electric heater on top of the disc which is superimposed .on top of the evaporating dish containing the solution to be evaporated instead of below which is the usual-method used in laboratories. By so placing the heat on top of the solution excessive boiling over and spattering will not take place. The method will be just as effective'insofar as loss br contamination isconcerned as if. a water bath were used in evaporation of the aqueous or other solutions, andmore rapid.
,In the drawings:
i Figure 1 is a side elevation of the improvement .in applied position in which. a Bunsenburner is being used for heating the disc.
Figure 2 isa top plan. viewof the disc.
Figure 3 showsthe construction in full of the disc.'-." Figure 4 is a side elevation of the improvement in applied position in which an electric heating element is used to heat the disc.
Figure 5 showsthe construction' of the electric heating element. v
i Itwill be noted as the description progresses subject matter of this invention, is to be used in place of the well known customary water bath. In the evaporating process of various aqueous or volatile solutions which may contai'nfseveral is used in many instances. The customary procedure, is to place the evaporating dish or beaker in a water bath and evaporate the solution by the slow means of boiling the water in the Water bath.
My improvement consists of a disc 1 which is to be made. in varying sizes tofit the numerous sizes of laboratory evaporating dishes 'or beakers; this disc is made of quartz, nickelor some kind, as the case may be.
other metal or material which is rust resisting and non-corrosive. v The. disc 1, as disclosed by the drawings is placedon top of the evaporating dish. The disc tantly provided with longitudinal and transverse lugs which are provided on the bottom side to providethe same withwhat I term lugs 3 andthe inner corners of these lugs are notched to form the, same'with projectingfingers 4. -The shoul- '1, at points adjacent to itsperiphery, is equidis+ 60 ders inward of the fingers 4 rest on the dish 2, I
while the fingers 4 contact with the outer periphcry of the dish in such a manner that the disc is held firmly in placeon the dish.
The disc -1- is approximately one eighth inch thick, but 'may be made thicker if so, desired. The disc, as. stated, is made of rust resisting or non-oxidizingmaterial- As the disc becomes very hot it is'impossible for the material to oxidize, as
the steam or vapors that are. evolved will not come in contact with the disc due to the heat on the under side. i
The disc 1 being arranged over the top of the dish which contains the solution to beevaporated in which embody the salts or solid matter of any 801 The solution will be completely evaporated to a total solid'without contamination or the loss by being spattered or boiled over as would be the case if the fiame'were put under the evaporating dish. efiect of the disc with the heat on the upper side i is similar to the directv rays of the sun or heat,
and the evaporation by this method is very rapid and eflicient.
The Bunsen gas burner may be. used in evap- E In fact, the 851' oration or aqueous solutions where it is desired to evaporate the same to a total solid. The I electric plateis to be used as the source of heat where it is desired to evaporate volatile solutionsp A very novel feature of this apparatus is, volatile solutions may be evaporated with no danger of fires or explosions when the disc is used in conjunction-with the electric plate.
The electric heater 5 is constructed with a metal ring 6 on which insulating blocks '7 are placed, and ahigh resistance coil 8 of German silver, iron or some other high resisting metal is usedfor the heating elements. The resistance wires are connected to wire conductors and'run through insulating, tubes to the electrical source. The metal ring is provided with a metal plate on top 9. The underside is leftopen so that the heat may be more efiiciently transmitted to the disc 1. e I
Having described the invention, I claim:
1. Evaporating'means comprising a disc, legs depending from the disc and shaped to engage the upper edge of a dish containing the fluid to be evaporated, and means above the disk for gro'ecting heat rays downwardly through the 2. Evaporating means comprising a dish to contain fluid to be evaporated, a disc arranged above the dish and spaced from the latter to provide a vapor outlet, legs for supporting the disc above above the dish, and meanslabove the disk for projecting heat rays downwardly through the disc into the dish.
3. Evaporating means comprising a dish to contain the substance to be evaporated, a disc being open to permit heat rays from the electric heating element to project downwardly into the dish.
