The falling chute is especially suitable for the measurement of agglomerates of dry powders or for determining the particle size distributions of free-flowing, coarse-grained materials which you would like to measure without dispersion.
The sample is transported with an electronically controlled feeder directly above the intake funnel of the falling chute, from where it falls directly into the measuring cell and is measured by the laser beam without any dispersion at all. Afterwards, the integrated exhaust system ensures automatic sample exhaustion.
Due to the fact, that the measurement is made without any dispersion, no compressed air supply is required. For exhausting the sample material, an external exhaust system is necessary, which can be ordered as a FRITSCH accessory together with the instrument.
Depending on the sample material, the falling chute is also an option where a compressed air connection is unavailable.
In order to use the FRITSCH Falling Chute you will need the ANALYSETTE 22 NanoTec Measuring Unit (Order No. 22.8000.00) and an exhaust system.
