Claim 1
Independent Claim
204 words
In a photometric solution analyzer of the rotary type wherein a carousel includes a multiplicity of improved cuvettes, said carousel being journaled on a shaft driven by a motor, said analyzer further including means for permitting transfer of radiant energy from a source thereof to a detector therefor along an optical path passing through at least a part of each of said cuvettes, said cuvettes being disposed about said carousel for receiving and mixing a reagent and a sample, each improved cuvette comprising: a sample holding means being disposed in each cuvette for receiving the sample, said means being located radially outward from the center of said carousel; and, a chamber being disposed for receiving the reagent, said chamber being located below said sample holding means and radially inward of said sample holding means, said chamber further being disposed in the optical path so that radiant energy is passed therethrough, whereby rotation of said carousel at a first speed allows the radiant energy to pass through the reagent prior to mixing with the sample, and rotation at a second speed causes the reagent in each cuvette to flow towards said sample holding means to effect mixture of the reagent with the sample for analysis.
Claim 2
Dependent Claim
204 words
In a photometric solution analyzer of the rotary type wherein a carousel includes a multiplicity of improved cuvettes, said carousel being journaled on a shaft driven by a motor, said analyzer further including means for permitting transfer of radiant energy from a source thereof to a detector therefor along an optical path passing through at least a part of each of said cuvettes, said cuvettes being disposed about said carousel for receiving and mixing a reagent and a sample, each improved cuvette comprising: a sample holding means being disposed in each cuvette for receiving the sample, said means being located radially outward from the center of said carousel; and, a chamber being disposed for receiving the reagent, said chamber being located below said sample holding means and radially inward of said sample holding means, said chamber further being disposed in the optical path so that radiant energy is passed therethrough, whereby rotation of said carousel at a first speed allows the radiant energy to pass through the reagent prior to mixing with the sample, and rotation at a second speed causes the reagent in each cuvette to flow towards said sample holding means to effect mixture of the reagent with the sample for analysis.
Claim 3
Dependent Claim
29 words
An improved cuvette structure as defined in claim 1 further characterized by a second chamber being disposed above and radially inward of said chamber for receiving a second reagent.
Claim 4
Dependent Claim
28 words
An improved cuvette structure as defined in claim 1 further characterized by selected ones of said cuvettes, when arranged in a carousel of cuvettes, including mechanical-to-electrical timing means.
Claim 5
Dependent Claim
28 words
An improved cuvette structure as defined in claim 1 further characterized by said sample holding means including a lip extension disposed for increasing the sample holding means size.
Claim 6
Dependent Claim
25 words
An improved cuvette structure as defined in claim 1 further characterized by said carousel including a collar disposed for securing said carousel to said shaft.
Claim 7
Dependent Claim
19 words
An improved cuvette structure as defined in claim 1 further characterized by said first speed being about 60 RPM's.
Claim 8
Dependent Claim
21 words
An improved cuvette structure as defined in claim 1 further characterized by said second speed being about 120 to 400 RPM's.
