Dry and wet disperser OASIS/M combines the renowned dry disperser RODOS/M (bottom) with
the dosing device VIBRI and the wet disperser SUCELL/M (on top).
OASIS/M combines powerful dry and wet dispersers in a single device. It consists of the renowned dry disperser RODOS/M in the lower part and a special adaptation SUCELL/M of the well established wet disperser SUCELL on the upper part. Both units operate fully automatic under the control of the WINDOX 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/M are set and the unit is ready for the operation of the dry disperser.
OASIS/M can be used with all members of the HELOS family. For operation of RODOS/M an extraction unit is necessary for sample collections and the generation of a laminar air flow in the measuring zone of the HELOS.
The SUCELL/M add-on can be used for future expansion of RODOS/M to OASIS.
As OASIS/M consists of two independent modules RODOS/M and SUCELL/M the options of both separate units can be selected.
For the optimum adaptation to the particle size the RODOS/M dispersing line is available with inner diameters of
recommended for 0.1 µm < xmax < 1000 µm,
|recommended for 1 µm < xmax < 2000 µm) and|
|recommended for 10 µm < xmax < 3500 µm.|
Dosing options for RODOS/M:
Prerequisite of a good dispersion is a smooth and homogeneous dosing. Two different dosing options are available: The vibratory feeder VIBRI serves most of the applications. For applications requiring micro-dosing please refer to the ASPIROS.
|Small volume adapter (SVA) for applications with less than 60 ml of suspension.||Supply rack with:
- Fill container with pump and level sensor.
|Different gasket-sets and hose materials for special liquids, e.g. Viton.|
Laser Diffraction Sensors
SUCELL/M stainless steel basin with speed controlled stirrers, level sensors, rinsing, cleaning and additive inlet nozzles
SUCELL/M side view with peristaltic pump on the rear and connectors for external supply units.
SUCELL/M connectors for filling, rinsing, draining and additive supply.
SUCELL/M stainless steel flow through cuvette with fast-lock mechanism for simple cleaning.
The control panel of OASIS/M allows for the manual control of both dispersing units. The button in the top centre selects dry or wet.
