CSTRs facilitate rapid dilution of reagents through mixing. This may be adjusted by incubation time and dilution. Flocculation is improved with optimum polymer dosage, polymer dilution and mixing. Magnitude of residual errors from these sources depends on geometric dilution of precision. It can be measured for any fluid system with no dilution or other sample preparation. Mixing can be combined with power plant or wastewater plant dilution. It works on concentrated dispersions without dilution. There is no fundamental limiting low temperature of dilution refrigerators. It works on any concentrated dispersions without dilution, including foams. These uses include substance dilution and cell container rinsing. Several processes are involved&colon; thickening / dilution, displacement and diffusion. The main excretion processes were fecal egestion, growth dilution and loss across respiratory surfaces. Ten parts per billion is equivalent to a homeopathic dilution of 4C. The sample is stored in conditions identical to the dilution method. This may be due to improper preparation or intentional low dilution.
