Description

The Hydro SM is a cost effective wet sample dispersion unit designed for measuring samples in non-aqueous dispersants where solvent usage needs to be minimized. Ideal for applications where sample volume needs to be minimized, the Hydro SM is a manually controlled pump and stirrer dispersion unit featuring: Small sample volume from 50ml -120ml. Continuously variable single shaft pump and stirrer with digital readout. Software driven SOPs with appropriate user prompts to assist with adherence to GLP and ensure reproducibility of measurements. Manual fill, drain and cleaning. Chemically compatible as standard. Wet sample dispersion units use a liquid dispersant, aqueous or solvent based, to disperse the sample. In a wet dispersion, individual particles are suspended in a liquid dispersant. The wetting of the particle surfaces by the dispersant molecules lowers their surface energy, reducing the forces of attraction between touching particles. This allows them to be separated and go into suspension. In order to keep the sample suspended and homogenized it is recirculated continuously through the measurement zone. For dispersants with high surface tension, such as water, the addition of a small amount of surfactant can significantly improve the wetting behavior and subsequent particle dispersion. In order to disperse individual particles it is usual to apply some energy to the sample. Often this is through stirring or agitation, but for very fine materials or strongly bound agglomerates ultrasonic irradiation is sometimes used.
