Particle size analyzer dispersion unit OASIS/L

drywet

OASIS combines powerful dry and wet dispersers in a single device. It consists of the renowned dry disperser RODOS in the lower part and a special adaptation of the well-established wet disperser SUCELL on the upper part. Both units operate fully automatic under the control of the software or manually via the control panel The change between dry and wet dispersion is done within a few seconds. Pressing a button on the control panel or giving a command by software and the flow through cuvette is lowered into the measuring position. All dispersion parameters such as pumping and stirrer speeds are set and the unit is ready for the operation of the wet disperser. A second command lifts back the cuvette into its protection housing. Now all parameters of the RODOS are set and the unit is ready for the operation of the dry disperser. When performing dry measurements with RODOS, the dosing of the powder sample is performed by the precision vibratory feeder VIBRI, which guarantees optimum sample concentration in the free aerosol jet in the measuring zone through a consistent, controlled product supply. The perfectly coordinated combination of measuring range, dosing and dispersion enables a product-specific and precise and repeatable particle size analysis far into the submicron range. Feed rate, dispersion energy, position of the dispersing line and the trigger for the recording of measurements can be automatically reproduced – reliably for every measurement. When switching to wet measurement the SUCELL flow cuvette extends at the push of a button into the measuring zone.
