SH0820

The SH0820 Washburn sorption cell for contact angle measurements on powders and pigments is made of stainless steel and specially designed for maximum reproducibility of sample preparation. The bottom of the cell is fitted with a filter paper, followed by the insertion of the provided sorption glass tube. Finally, a cap is screwed onto the cell and presses the tube against the cell's bottom, keeping the paper filter absolutely fixed. With this method, the pressure on the filter from below when immersing the powder-filled tube cannot influence the measurement. Powder wetting analysis can be even more accurate when combining the SH0820 Washburn sorption cell with our separately available preparation set SH0824.    

The SH0812 force sensor adapter is additionally required for using the sorption cell SH0820. One set of matching filter paper is included and also available from us in sets of 100 filters with the designation SH0823. Spare glass tubes with the designation SH0822 can also be ordered.
