Liquid Sample Handling Units
The Saturn DigiSizer II’s sample handling unit ensures that every sample will be correctly dispersed. Micromeritics’ patented, state-of-the-art liquid sample handling units (LSHU) work with the instrument software to assure that sample suspension is of the proper concentration. A continuous flow through the reservoir provides a mixing action sufficient to keep all sample material suspended and prevents the settling of particles. The LSHU has several automated features such as a built-in ultrasonic probe, automatic liquid level control, particle concentration detection, and a sample circulation system that continuously maintains dispersion. Auto-dispersion and auto-dilution features monitor the sample’s concentration and add liquid as needed until optimum concentration is obtained.
To reduce the possibility of sample carryover between analyses, the LSHU has a patented reservoir rinse design. While other designs simply fill and empty the reservoir to rinse, the Saturn DigiSizer’s LSHU has a feature that sprays the reservoir walls as the fluid level recedes. This removes residue that otherwise might cling to the surface.
The LSHU System is available in two configurations, a standard version and a low-volume version. Micromeritics can help you determine the LSHU that fits your specific needs.
