Abstract

The invention relates to a melting apparatus (100) for melting paraffin (1), having: a melting container (110) for receiving paraffin (1) to be melted; a storage container (190) for storing molten paraffin (4); having a melting container heating device (120) for heating the melting container (110), having a storage container heating device (191) for heating the storage container (190), having a fluid connection (113) fluidically connecting the melting container (110) and the storage container; the melting container (110), the storage container (190), and the fluid connection (113) being arranged so that molten paraffin (4) flows out of the melting container (110) into the storage container (190).

First claim

What is claimed is:

1. A laboratory device having a melting apparatus ( 100 , 200 ) for melting paraffin ( 1 ), the melting apparatus ( 100 , 200 ) comprising:
a melting container ( 110 , 210 ) for receiving paraffin ( 1 ) to be melted;
a plurality of metallic bodies ( 2 ) received in the melting container ( 110 , 210 ), wherein each of the plurality of metallic bodies received in the melting container is embedded in the paraffin ( 1 ) or mounted in the melting container ( 110 , 210 );
a storage container ( 190 ) for storing molten paraffin ( 4 );
a melting container heating device ( 120 ) for heating the melting container ( 110 , 210 ), the melting container heating device ( 120 , 220 ) comprising an inductor for inducing eddy currents in the plurality of metallic bodies ( 2 ) received in the melting container ( 110 , 210 );
a storage container heating device ( 191 ) for heating the storage container ( 190 );
a fluid connection ( 113 ) fluidically connecting the melting container ( 110 , 210 ) and the storage container;
wherein the melting container ( 110 , 210 ), the storage container ( 190 ), and the fluid connection ( 113 ) are arranged so that molten paraffin ( 4 ) flows out of the melting container ( 110 , 210 ) into the storage container ( 190 ); and
wherein the storage container ( 190 ) includes a measuring device ( 192 , 320 ) for measuring the weight or volume of the molten paraffin ( 4 ) in the storage container ( 190 ).

2. The laboratory device according to claim 1 , the melting container ( 110 , 210 ) comprising an outflow ( 112 ) from which the fluid connection ( 113 ) proceeds.

3. The laboratory device according to claim 2 , the outflow ( 112 ) comprising a valve ( 230 ).

4. The laboratory device according to claim 2 , the melting container ( 110 , 210 ) comprising a floor ( 111 ) that slopes downward toward the outflow ( 112 ).

5. The laboratory device according to claim 4 , the floor ( 111 ) comprising a funnel-shaped portion.

6. The laboratory device according to claim 1 , wherein the laboratory device is configured to keep a predefinable quantity of molten paraffin on hand in the storage container ( 190 ).

7. The laboratory device according to claim 1 , further comprising a withdrawal pump ( 193 ) and/or an outflow for withdrawing molten paraffin ( 4 ) from the storage container ( 190 ).

8. The laboratory device according to claim 1 , the melting container ( 110 , 210 ) comprising a measuring device for measuring the weight and/or volume of the paraffin to be melted.

9. The laboratory device according to claim 1 , wherein the inductor induces eddy currents in a floor and/or a wall of the melting container ( 110 , 210 ).

10. The laboratory device according to claim 1 , the melting container heating device ( 120 , 220 ) comprising a resistance heating element.

11. The laboratory device according to claim 1 , the storage container heating device ( 191 , 310 ) comprising an inductor for inducing eddy currents in a floor and/or a wall of the storage container ( 190 , 300 ).

12. The laboratory device according to claim 1 , further comprising a plurality of metallic bodies ( 2 ) received in the storage container ( 110 , 210 ), wherein each of the plurality of metallic bodies received in the storage container is embedded in the paraffin ( 1 ) or mounted in the storage container ( 110 , 210 ), the storage container heating device ( 191 , 310 ) comprising an inductor for inducing eddy currents in the metallic bodies ( 2 ) received in the storage container ( 190 , 300 ).

13. The laboratory device according to claim 1 , the storage container heating device ( 191 , 310 ) comprising a resistance heating element.

14. A laboratory device having a melting apparatus ( 100 , 200 ) for melting paraffin ( 1 ), the melting apparatus ( 100 , 200 ) comprising:
a melting container ( 110 , 210 ) for receiving paraffin ( 1 ) to be melted;
a storage container ( 190 , 300 ) for storing molten paraffin ( 4 );
a plurality of metallic bodies ( 2 ) received in the storage container ( 190 , 300 ), wherein each of the plurality of metallic bodies received in the storage container is embedded in the paraffin ( 1 ) or mounted in the storage container ( 190 , 300 );
a melting container heating device ( 120 ) for heating the melting container ( 110 , 210 );
a storage container heating device ( 191 , 310 ) for heating the storage container ( 190 , 300 ), the storage container heating device ( 191 , 310 ) comprising an inductor for inducing eddy currents in the plurality of metallic bodies ( 2 ) received in the storage container ( 190 , 300 );
a fluid connection ( 113 ) fluidically connecting the melting container ( 110 , 210 ) and the storage container;
wherein the melting container ( 110 , 210 ), the storage container ( 190 , 300 ), and the fluid connection ( 113 ) are arranged so that molten paraffin ( 4 ) flows out of the melting container ( 110 , 210 ) into the storage container ( 190 , 300 ); and
