Dosing powder in the mg range

The patented µPTS is based on the PTS technology and allows precise dosing of very small amounts (<1 mg) of powder in less than a second, with an accuracy reaching up to 2 % RSD. The product is filled in a calibrated chamber of adjustable volumes by the action of vacuum and emptied mechanically by a piston.

The revolutionary system does not include any filter and can therefore handle very fine and/or sticky materials.


A specially designed hopper allows to handle a large range of powders with difficult behaviours.


The volume can be changed automatically by using a linear motor which can be controlled in a closed loop linked to a weighing device.


The system is very compact and versatile and can be easily dismantled. Another main advantage is its easy integration into dosing stations with multiple filling systems or products.
