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 storage container ( 190 ) for storing molten paraffin ( 4 ); a melting container heating device ( 120 ) for heating 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 , the melting container heating device ( 120 , 220 ) comprising an inductor for inducing 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 an inductor for inducing eddy currents in metallic bodies ( 2 ) received in the melting container ( 110 , 210 ).

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

12 . 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 ).

13 . The laboratory device according to claim 1 , the storage container heating device ( 191 , 310 ) comprising an inductor for inducing eddy currents in metallic bodies ( 2 ) received in the storage container ( 190 , 300 ).

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