Combo tube and cuvette rack

thingiverse

User rhonan uploaded couple of multi-purpose tube racks. I found one that I really enjoyed using - the one for 2 × 50 mL falcon tube, 4 × 15 mL falcon tube and 6 × eppendorf tube. However, my tubes were a little loose fitting and since I also use spectrophotometer quite often, I also needed a rack for cuvettes. The project was calibrated for falcon and eppendorf tubes produced by Nest (15/50/1,5-2 mL) and cuvettes supplied by VWR/Fisherbrand. There are two projects - tight, and not-so-tight, were the inserts are widened by 0.2 mm. I use the tight one with Nest tubes and it is mint. Thanks to rhonan for the original thing.
