Plastic tube holder for the ball mill

The largest holder tested was for 18 tubes (2 mL) with a round bottom, so it was possible to grind up to 36 samples (100 mg) in parallel.

Designed for used with the MM200 or MM400 ball mills. The models differ slightly in the shape of the seat in order to best fit also the jaws of the mill.

The weight of the largest tested adapter (3x6) is still lower than the 25 mL metal grinding container, so the mill will not be overloaded if the tubes are placed symmetrically.

The SCAD models can be used to adapt to individual requirements. The model can be easily adapted to other dimensions of plastic tubes.

Such a holder was successfully used, for example, for the preparation of co-crystals, see: "Exploring the polymorphism of sofosbuvir via mechanochemistry: effect of milling jar geometry and material" DOI:10.1039/d1ce01561c
