Cuvette Holder - PE Lambda 19

thingiverse

Holder for 1.5ml cuvettes for use with a Perking Elmer Lambda 19 spectrophotometer, and is designed to fit over the existing dovetail mount. Updated Feb 2016 to include both orientations. There is an icon in the upper right corner of each showing the light path relative to the cuvette orientation. The narrow version is the standard orientation, where the light beam takes the longer path through the rectangular cuvette. The wide version rotates the cuvette 90° from standard, because some of my people wanted to do it that way. Additional work was done to make the holders stronger, and to better key the holders for their orientation (my people discovered they could force cuvettes in the narrow orientation into the wide holder, which also breaks off the front of the old holder) Instructions Can be printed in ABS or PLA. We've had good luck using 0.2mm layer height and haven't seen any effects of print density on the result.
