| flotation | 1. The act, process, or state of floating. 2. The science of floating bodies. Center of flotation. The imaginary surface which all the planes of flotation touch when a vessel rolls or pitches; the envelope of all such planes. Origin: Cf. F. Flottation a floating, flottaison water line, fr. Flotter to float. See Flotilla. Source: Websters Dictionary (01 Mar 1998) |

| flotation constant | Characteristic sedimentation behaviour of a lipoprotein fraction of plasma in a centrifugal field in a medium of appropriate density, achieved by adding a salt or D2O to the plasma. Synonym: negative S, Svedberg of flotation. (05 Mar 2000) |
| flotation method | Any of several procedures for concentrating helminth eggs for more reliable results when eggs are difficult to find in direct examination; the flotation method's depend on flotation of helminth eggs on the surface of a liquid of sufficiently high specific gravity, approximately 1.180; 1 part faeces mixed in about 10 parts saturated saline will float most protozoan cysts and nonpercolated helminth eggs. See: zinc sulfate flotation centrifugation method. (05 Mar 2000) |

| zinc sulfate flotation centrifugation method | A flotation method in which the faecal specimen is suspended in tap water, strained through wet gauze, centrifuged, resuspended in tap water, washed and recentrifuged several times, and then suspended in 33% solution of zinc sulfate and centrifuged at top speed for 45 to 60 sec; a bacteriologic loop may be used to pick up the surface layer, which contains protozoan cysts and helminth eggs.

Flotation is a method for the separation of mixtures. Flotation is a separation technique used widely in the minerals industry, for paper deinking and water treatment amongst others. The technique relies apon differences in the surface properties of different particles to separate then. The particles that are to be floated are rendered hydrophobic by the addition of the appropriate chemicals. ...

| flotation |
A technique for the recovery of plant remains from archaeological sites. Sediments or pit contents are poured into water or heavy liquid; the lighter, carbonized plant remains float to the top for recovery, while the heavier sediments and other materials fall to the bottom.

| flotation |
the process of recovering small particles of organic material by immersing sediment samples in water or other fluids and skimming off the particles which float on the surface. An important method for obtaining microfloral and microfaunal remains and carbon samples.
