Method and Apparatus for Filtrate Storage Handling
A method of removing a filtrate storage bottle from a water bath includes inserting at least two finger underneath a radially protruding lip of a filtrate storage bottle sealing cap and raising the at least two fingers to lift the bottle from the water bath. A side wall portion of the filtrate storage bottle sealing cap is smaller in perimeter than a circle surrounding the radially protruding lip. The cap creates a liquid tight seal with the filtrate storage bottle.
1 . A storage bottle sealing cap comprising:
an upper portion having a top surface and a radially protruding lip;
a side wall portion connected to the upper portion, the side wall portion having an outer surface with a smaller perimeter than the radially protruding lip and an inner surface including a thread forming a helical ridge; and
a plurality of ribs having a concave profile, the plurality of ribs connected to the sidewall portion and the radially protruding lip.
2 . A sealing cap according to claim 1 , wherein the outer edge includes surface ridges thereon.
3 . A sealing cap according to claim 1 , further comprising a sealing ring extending from a bottom surface of the upper portion.
4 . A sealing cap according to claim 1 , wherein the outer surface of the side wall portion decreases in perimeter away from the upper portion.
5 . A sealing cap according to claim 1 , wherein the outer surface of the side wall portion concaves radially inward.
6 . A sealing cap according to claim 5 , wherein a section of the side wall outer surface has a constant perimeter.
7 . A sealing cap according to claim 1 , wherein the top surface of the upper portion is flat.
8 . A sealing cap according to claim 1 , wherein the top surface of the upper portion is specially adapted to receive labeling information.
9 . A sealing cap according to claim 1 , wherein the plurality of ribs has a concave profile.
10 . A liquid filtration kit comprising:
a reservoir,
a filtrate storage bottle;
a filter for use in between the reservoir and the filtrate storage bottle; and
a filtrate storage bottle sealing cap including:
an upper portion having a top surface and a radially protruding lip comprising an outer edge; and
a side wall portion connected to the upper portion, the side wall portion having an outer surface with a smaller perimeter than the radially protruding lip.
11 . A liquid filtration kit according to claim 10 , wherein the outer edge includes surfaces ridges thereon.
12 . A liquid filtration kit according to claim 10 , further comprising:
a vacuum collar, for coupling a vacuum source such that a pressure differential is created that draws a sample from the reservoir through the filter and into the filtrate storage bottle.
13 . A filtrate storage system comprising:
a filtrate storage bottle; and
a filtrate storage bottle sealing cap characterized by:
an upper portion having a top surface and a radially protruding lip comprising an outer edge; and
a side wall portion connected to the upper portion, the side wall portion having an outer surface with a smaller perimeter than the radially protruding lip.
14 . A filtrate storage system according to claim 13 , wherein the outer edge includes surface ridges thereon.
15 . A filtrate storage system according to claim 13 , wherein the outer surface of the side wall portion decreases in perimeter away from the upper portion.
16 . A filtrate storage system according to claim 13 , wherein the outer surface of the side wall portion concaves radially inward.
17 . A filtrate storage system according to claim 16 , wherein a section of the side wall outer surface has a constant perimeter.
18 . A filtrate storage system according to claim 13 , wherein the top surface of the upper portion is specially adapted to receive labeling information.
19 . A filtrate storage system according to claim 13 , further comprising a plurality of ribs connected to the sidewall portion and the radially protruding lip.
20 . A filtrate storage system according to claim 13 , further comprising a sealing ring extending from a bottom surface of the upper portion.
