Particle size analysis of suspensions and emulsions with the wet disperser QUIXEL mounted in the measuring zone of the laser diffraction sensor HELOS/BR for fast measurement cycles of even very coarse and dense materials.
QUIXEL is the advanced wet dispersing system suitable for particle size analysis on all kinds of suspensions and emulsions in the size range of 0.1 µm to 3.5 mm. Its innovative, tubeless design enables very fast measuring cycles. Even high density particles such as 3 mm ball bearing beads made from stainless steel are safely transported in water through the flow through cell without the need for using special liquids of high viscosity. The wet dispersion process is supported by a built-in ultrasonication unit, which is adjustable by software from 0 to 60 W in 1% steps.
The operation is fully automated. All parameters such as pumping speed etc. are controlled by software. The interface to external sampling and sample preparation stages is fully supported. Special top-lids with automated additive supply are available as an option.
QUIXEL is available in two versions: with a stainless steel flow through cuvette of 2 mm or 6 mm. The following options are available as add-on.
|Stainless steel flow cuvette for QUIXEL with screw-mounted windows. Window spacing: 2 mm, gasket material: Viton®, applicable for SUBMICRON.||Supply rack with:
- Fill container with pump and level sensor.
|Stainless steel flow cuvette for QUIXEL with screw-mounted windows. Window spacing: 6 mm, gasket material: Viton®.|
|EPDM gasket-set for QUIXEL
ketene proof, retro fitting at factory location only
|Rinsing cover for QUIXEL, complete, with the function “rinsing sample glass” and “additive supply” in combination with the support rack.|
|NBR gasket-set for QUIXEL
retro fitting at factory location only
|Additive cover for QUIXEL, complete

Laser Diffraction Sensors
Top view with the stainless steel basin, the centrifugal pump on the bottom and two liquid level sensors for automatic filling to 250 ml and 1000 ml.
The side view is showing the removable cover of the steel flow through cuvette, the glass cover on top and the connections for filling and draining.
On the left side the auxiliary connectors for external automated filling, draining and additive supply are visible.
All functions such as filling, degasing, sonication, circulating, draining, the pumping speed, the temperature of the suspending liquid, additive supply and the insertion and release of the cuvette can be set manually by the control panel at the front.
