Another way to measure the expressible moisture in a centrifuge is to use some type of filter system so that the free solution is collected below the sample. This involves specialized equipment in each centrifuge tube that subsequently needs to be cleaned. 

Fig. 5. (Opposite page) Pictorial representation of GenDecoder specialized for functional analysis of genetic information. (A) Flow chart of cell-free expression process. (B) A photograph of GenDecoder, dimensions 1.5 m (W), 0.85 m (D), and 1.8 m (H). The robot is equipped with three robotic arms for pipetting and plate transfer, one incubator for transcription and translation, maximum capacity four plates, and centrifuge for mRNA recovery after ethanol precipitation. Incubator capacity can be increased by handling plates manually. (C) Proteins in 1 pL from each translated mixture were analyzed as in Fig. 4, thus 0.2 pL of original translational mix.

The equipment used for dewatering includes filters and screening devices of various types, centrifuges, hydrocyclones, extrusion and expression presses, water extractors, and thickening, clarifying, and flotation hardware. The processing methods encompass a broad range of water-removal techniques. They... 

Solid-liquid separation systems generally consist of four stages including pretreatment, solid concentration in thickeners, solid separation in filters or centrifuges, and post-treatment by expression and washing operations. There are different types of SLS equipment served for different functions in relation to the four stages. Product specification, characteristics of solid-liquid suspension, solid settling velocity, rate of cake... 

Determination of the critical gas flow rate and the CE of a separator equipped with a string droplet catcher orifice requires a preliminary determination of gas-liquid flow parameters in the entire system, including the supply pipeline, the settling section of the separator, and the droplet catcher orifice - in the same way as it was done earlier for a separator with a centrifugal orifice. The outcome is the following pair expressions for the CE s of a vertical and a horizontal separator... 

Gravity sedimentation equipment, hydrocyclones, sedimenting centrifuges or flotation cells have also been extensively used in mineral processing for separation of minerals according to density or affinity to water. In such separations, the efficiency is expressed by the Tromp curve which, similar to the grade efficiency curve, shows probability of separation as a function of material density or mineral composition. The steepness of the curve is a measure of the sharpness of the separation.
