The small volume wet dispersion unit SVA ensures perfect, fully automatic dispersion of samples which are only available in a minimal quantity. And for measurements in organic solvents, the unit needs less than 50 ml liquid for the entire measurement circuit. This minimises the disposal costs and decreases environmental pollution.
For this purpose the ANALYSETTE 22 Small Volume Dispersion Unit SVA is available, which can be optionally utilised with our Wet Dispersion Unit (22.8500.00) or as the only dispersion unit in combination with the NanoTec Measuring Unit (22.8000.00).
Water soluble products, pharmaceutical products, chemicals, food, emulsions.
Thanks to ultrasonic power of up to 100 Watt, strongly bound agglomerates are quickly and effectively degraded, with perfect results. The ultrasonic power and the dispersion duration can both be controlled directly by the software. Due to a separate soundproof ultrasonic chamber, the operation of the small volume wet dispersion unit SVA is pleasantly quiet. The illumination of the dispersion bath ensures simple operation – and the integrated water connection ensures automatic cleaning and filling after each measurement.
The entire dispersion and measurement sequence – start, pump speed, valve opening, cleaning and analysis – runs fully automatically, using preset or user definable SOPs of the software MaS control. For easy work processes with best results.
All parts of the small volume wet dispersion unit SVA, coming into contact with the dispersion liquid are made of high-quality stainless steel, PTFE, BK7 glass, Viton® Extreme or silicone and suitable for use with benzine, alcohol and many organic solvents as suspension liquids. If you are working with extremely aggressive chemical dispersion liquids, like for example acetone or dimethylketone, you can order the SVA dispersion unit with the conversion kit for extreme chemical resistance. The kit consists of seals, O-rings and flow plate made of FFKM Kalrez® – the hoses are made of Santoprene®. If you already have a unit, you can order the conversion kit separately and your equipment can be retrofitted. You can download a list of chemicals for the different dispersion units here:
In order to use the FRITSCH Small Volume Wet Dispersion Unit SVA, you will need the ANALYSETTE 22 NanoTec Measuring Unit (Order No. 22.8000.00).
