Abstract
Abstract A cleansing apparatus for test-vessels such as cuvettes or the like comprising a support shaft and three spaced paralleled disks, two of said disks being secured to the shaft and the third disk being rotatably positioned on the shaft, a nozzle secured to the first disk, the second and third disks having apertures thereon for receiving cuvettes, so that a cuvette may be positioned over the nozzle through the apertures in one of the disks, and retained by the rotatable disk so that immersion of the apparatus into a cleansing solution forces a jet of solution through the nozzle for cleansing the cuvette.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
192 words
A cleansing apparatus for cuvettes comprising: a support shaft, first and second parallel disks secured perpendicularly to said shaft and spaced apart along said shaft a distance slightly less than the length of a cuvette to be cleansed, nozzle means mounted on and extending through said first disk and directed toward said second disk, said second disk having first aperture means therein aligned with said nozzle means so that a cuvette may be inserted through said first aperture means and over said nozzle means and the cuvette is retained against lateral displacement by said second disk, a third disk rotatably mounted on said shaft and having second aperture means therein capable of being aligned or misaligned with respect to said first aperture means by rotation of said third disk on said shaft, whereby a cuvette may be inserted through aligned first and second aperture means and over said nozzle means and retained by slight rotation of said third disk so that said first and second aperture means are misaligned and whereby immersion of said apparatus into a cleansing solution forces a jet of solution through said nozzle means for cleansing the cuvette.
Claim 2
Dependent Claim
192 words
A cleansing apparatus for cuvettes comprising: a support shaft, first and second parallel disks secured perpendicularly to said shaft and spaced apart along said shaft a distance slightly less than the length of a cuvette to be cleansed, nozzle means mounted on and extending through said first disk and directed toward said second disk, said second disk having first aperture means therein aligned with said nozzle means so that a cuvette may be inserted through said first aperture means and over said nozzle means and the cuvette is retained against lateral displacement by said second disk, a third disk rotatably mounted on said shaft and having second aperture means therein capable of being aligned or misaligned with respect to said first aperture means by rotation of said third disk on said shaft, whereby a cuvette may be inserted through aligned first and second aperture means and over said nozzle means and retained by slight rotation of said third disk so that said first and second aperture means are misaligned and whereby immersion of said apparatus into a cleansing solution forces a jet of solution through said nozzle means for cleansing the cuvette.
Claim 3
Dependent Claim
13 words
A cleansing apparatus as in claim 1 and wherein said disks are circular.
Claim 4
Dependent Claim
17 words
A cleansing apparatus as in claim 2 and wherein said disks are coaxially mounted on said shaft.
Claim 5
Dependent Claim
13 words
A cleansing apparatus as in claim 3 and wherein said disks are plastic.
Claim 6
Dependent Claim
31 words
A cleansing apparatus as in claim 4 and wherein said first and second aperture means each comprise six equally spaced apertures and said nozzle means comprises six equally spaced nozzle members.
Claim 7
Dependent Claim
21 words
A cleansing apparatus as in claim 5 and wherein said nozzle members each are conical and pointed toward said second disk.
Claim 8
Dependent Claim
22 words
A cleansing apparatus as in claim 6 and wherein said shaft includes a handle at the end remote from said first disk.
Claim 9
Dependent Claim
26 words
A cleansing apparatus as in claim 7 and wherein said shaft includes two spaced flanges secured thereon and said third disk is rotatable between said flanges.
Claim 10
Dependent Claim
17 words
A cleansing apparatus as in claim 8 and wherein said disks are axially adjustable along said shaft.
Claim 11
Dependent Claim
32 words
A cleansing apparatus as in claim 1 or 8 and including a receptacle for containing a cleansing solution and having an inside dimension slightly greater than the outer dimensions of said disks.
