Column racks for microcolumn separations

Microcolumn racks designed for our clean lab.These have a small platform so that the collection vial can be placed close to the column, so that splashes can't escape the vial. When the platform is raised there is space for a waste vial.They are numbered up to 40 (10 racks with 4 columns each).Print in PETG so that there's enough flex to squeeze the platform in. The platform locks in raised or lowered position.
