Abstract

A scraping device for removing dry substances that have adhered to the interior surface laboratory vessel. The scraping device comprising a handle, a curved hook, a ribbed edge, an elbow joint, and a scraping tip. The hook part of the scraping device conforms to the curvature of the interior surface of a round laboratory vessel such as a volumetric flask, Florence flask, and round bottom flasks. The elbow joint of the scraping device enables hook portion to pass through the long narrow neck found in most laboratory vessels.

Claims (61)

1 . A scraping device for scraping and removing substances from an interior surface of a vessel, comprising:

a handle;

an elbow joint;

a semi-circular hook;

a ribbed edge;

a scraping tip; and

a substance collection reservoir;

wherein the substance collection reservoir includes a physical chamber built into the scraping tip;

wherein the substance collection reservoir extends from an end of the scraping tip into at least 1% of a length of the semi-circular hook;

wherein the handle is connected to the semi-circular hook by the elbow joint;

wherein the semi-circular hook is operable to conform to the interior surface of the vessel;

wherein the ribbed edge is formed along an exterior surface of the semi-circular hook and provides a flush fit between the scraping device and the interior surface of the vessel;

wherein the ribbed edge is formed along the outside perimeter of the semi-circular hook in its entirety and acts as a scrapping edge to scrape the interior of the vessel;

wherein the semi-circular hook has a handle end and a distal end;

wherein the scraping tip is located at the distal end of the semi-circular hook and extends away from the distal end of the semi-circular hook;

wherein the vessel includes an opening and a neck; and

wherein rotation of the scraping device causes the ribbed edge to scrape a substance adhered to the interior side surface of the vessel, thereby removing the substance from the interior side surface of the vessel.

2 . The scraping device of claim 1 , wherein the ribbed edge includes serrations to increase applied pressure at each point of contact between the serrations and the interior surface of the vessel.

3 . The scraping device of claim 1 , wherein the ribbed edge includes bristles for removing substances from the interior surface of the vessel.

4 . The scraping device of claim 1 , wherein the ribbed edge includes a blade for removing substances from the interior surface of the vessel.

5 . A scraping device for scraping and removing substances off an interior surface of a laboratory vessel, comprising:

a handle;

an elbow joint;

a semi-circular hook;

a ribbed edge;

a scraping tip; and

a substance collection reservoir;

wherein the substance collection reservoir includes a physical chamber built into the scraping tip;

wherein the substance collection reservoir extends from an end of the scraping tip into at least 1% of a length of the semi-circular hook;

wherein the handle is connected to the semi-circular hook by the elbow joint;

wherein the semi-circular hook is operable to bend and conform to the interior surface of the laboratory vessel;

wherein the ribbed edge provides a flush fit between the scraping device and the interior surface of the laboratory vessel;

wherein the ribbed edge is operable to scrape substances that have adhered to the interior surface of the laboratory vessel;

wherein the laboratory vessel includes an opening, a body and a neck;

wherein a width of the body is wider than a width of the opening and/or neck;

wherein the semi-circular hook has a handle end and a distal end; and

wherein the scraping tip is connected to the distal end of the semi-circular hook and extends away from the distal end of the semi-circular hook.

6 . The scraping device of claim 5 , wherein the ribbed edge includes serrations to increase applied pressure at each point of contact between the serrations and the interior surface of the laboratory vessel.

7 . The scraping device of claim 5 , wherein the ribbed edge includes bristles for removing substances from the interior surface of the laboratory vessel.

8 . The scraping device of claim 5 , wherein the ribbed edge includes a blade for removing substances from the interior surface of the laboratory vessel.

9 . The scraping device of claim 5 , wherein the scraping device includes two hooks on opposite ends of the scraping device connected by the handle.

10 . A scraping device for scraping and removing substances off an interior surface of a laboratory vessel, comprising:

a handle;

finger grips;

an elbow joint;

a semi-circular hook;

a ribbed edge; and

a scraping tip;

wherein the handle is connected to the semi-circular hook by the elbow joint;

wherein the finger grips are indents within the handle;

wherein the semi-circular hook is operable to bend and conform to the interior surface of the laboratory vessel;

wherein the ribbed edge provides a flush fit between the scraping device and the interior surface of the laboratory vessel;

wherein the ribbed edge is operable to scrape substances that have adhered to the interior surface of the laboratory vessel;

wherein the laboratory vessel includes an opening, a body and a neck;

wherein a width of the body is wider than a width of the opening and/or neck;

wherein the semi-circular hook has a handle end and a distal end; and

wherein the scraping tip is connected to the distal end of the semi-circular hook and extends away from the distal end of the semi-circular hook.

11 . The scraping device of claim 10 , wherein the ribbed edge includes serrations to increase applied pressure at each point of contact between the serrations and the interior surface of the laboratory vessel.

12 . The scraping device of claim 10 , wherein the ribbed edge includes bristles for removing substances from the interior surface of the laboratory vessel.

13 . The scraping device of claim 10 , wherein the ribbed edge includes a blade for removing substances from the interior surface of the laboratory vessel.

14 . The scraping device of claim 10 , wherein the handle has a left and right side, wherein the finger grips are located on both the left and right side of the handle.
