cuvettes using multiple program settings including fixed wavelength, wavelength scanning, scatter correction, net A, time-based kinetic/rate determination, subtraction/addition, and spectra manipulation.</p> <p> </p> <p>Applications include:</p> <ul> <li>Quantitative Total Protein Analysis</li> <li>Nucleic Acid Determination</li> <li>Enzyme Mechanism</li> <li>Single Component Quantitative Analysis</li> <li>Multicomponent Analysis by Full Spectrum Quantitation (FSQT)</li> <li>Performance Validation</li> </ul></div> <div id="uid-7no27-2" class="tab-pane fade in "><p>The Beckman DU-640i Spectrophotometer micro-focused beam technology provides precise and accurate results for samples as small as 5uL. The micro-focused beam delivers the full energy of the beam to the microsample, unlike standard beams, which can lose as much as 80% of their energy when applied to a microvolume sample. UV and Vis lamps used with this instrument also have power switches that work independently from that of the system.</p></div> <div id="uid-7no27-3" class="tab-pane fade in "><p><strong>Fees</strong></p> <table style="width: 484px;"> <tbody> <tr style="height: 13px;"> <td style="width: 216.578px;
