UV/vis/fluorimeter cuvette holder with 4 LED slots for irradiation

<p>This was migrated from my Thingiverse profile and is from 2015.</p><p>A contraption which fits around a standard 1x1 cm (internal) pathlength UV/vis or fluorimeter cuvette. Four LEDs fit around the sides allowing the sample to be irradiated from all four sides while being magnetically stirred from below. Useful for <i>e.g.</i> repeated irradiation/spectrometry cycles in photochemical kinetics measurements.</p><p>LEDs kept at constant distance from sample: so long as they are well below the liquid level and efficient stirring is maintained, constant and uniform irradiation of the sample can be assumed.</p><p>The LEDs in the pictures are infrared and were used for infrared photopolymerisation research work. Other wavelengths may of course be substituted: all standard 5 mm LEDs should fit.</p><p>This was one of my first designs after getting the 3D printer in 2015.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>RepRap</p><p><strong>Printer:&nbsp;</strong></p><p>Ormerod 2</p><p><strong>Rafts:</strong></p><p>No</p><p><strong>Supports:&nbsp;</strong></p><p>No</p><p><strong>Notes:</strong></p><p>PLA standard settings.</p><h3>How I Designed This</h3><p>Designed in OpenSCAD, sliced with Slic3er.</p><p>&nbsp;</p>
