ChromoCreeper

A simple column holder and stand which can be mounted directly into microcentrifuge tube rack. For assembly one will need a spiral spring from clothespin, two M5 nuts DIN 934, two M5 screws 20-30 mm long (I prefer DIN 933 screw with printed knobs like https://www.thingiverse.com/thing:641854), a solid rod 8-12mm in diameter and 150-200mm long. The holes for the rod are intentionally made to accommodate for different diameters, depending on what you can source.
Please keep in mind that this is for light loads only! Don't put your beloved 20/600 glass column for SEC into these clamps.
