| Svedberg of flotation | 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) |

| Svedberg | <unit> A unit for measuring the rate at which a particle sediments in a centrifuge. The unit applied to the sedimentation coefficient of a particle in a high speed or ultracentrifuge. S= rate of sedimentation x 1/ rho exp2r Where rho is the speed of rotation in radians per second and r is the radius to a chosen point in the centrifuge tube. 1 Svedberg unit is defined as a velocity gradient of 10exp 13 seconds. Named after a pioneer of the ultracentrifuge. The units are nonadditive: a particle formed from two 5S particles will not have a sedimentation coefficient of 10S. (18 Nov 1997) |

| 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. (05 Mar 2000) |
| 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.
