4 shows a more detailed perspective of the transparent opal disc 305, 307 that fits the press on the body of the 311 bucket. The disc can be made of a transparent polymer at all LED wavelengths, for example acrylic, polysulfon, transparent PVC or PC. Not all qualities of these materials will be completely transparent at LED wavelengths, so it is important to measure transmission and determine the weakening of the spectrum signal of the material of the bucket body. 3 a and 3 b show a height and cross-section of an exemplary bucket body. 3 a and 3 b are orthogonal representations of the body of the bucket. 3 a shows the body of the bucket in a cross-section taken along the midline of fig.
Each manufacturer designs its instruments with a specific Z-dimension. When buying buckets with a small volume, the right Z-dimension becomes crucial. 1 cm cuvette Matching the Z-dimension of the bucket to the Z-dimension of the instrument ensures that the light beam passes through the middle of small samples.
The photodiode is housed in a similar 901 housing made of a non-transparent material to minimize the amount of ambient light entering the photodiode. An opal glass diffuser similar to the 908 installed for the photodiode can also be used to create a more even distribution of light hitting the photodiode. The outside of the opal glass 908 corresponds to the outer surface of the transparent disc 305, 307 FIG.
Testing samples in the field is possible with this portable module. Quality control and screening applications need an effective tool. In addition, reliable measurement ensures a high demand for the instrument. In addition, the increase in the use of the multicuvette spectrophotometer in the life sciences is another advance.
For measuring oxygen concentration and Hct, the optical properties of these extraordinary types of hemoglobin, i.e., carboxy, cyan and methamphetamine hemoglobins, can be ignored. There is a long-felt need for a bucket sensor that provides accurate measurements of absorption and transmission in blood and other fluids. There is also a need for a bucket that prevents this light phenomenon from being transmitted through the walls of the bucket to the light detector.
