| Czapek's solution agar | A culture medium used for the cultivation of fungus species and for identification of Aspergillus and Penicillium species. Synonym: Czapek-Dox medium. (05 Mar 2000) |
|---|---|
| heat of solution | <chemistry> The enthalpy change associated with dissolving a solute in a solvent. (09 Jan 1998) |
| saline solution | A solution of any salt. Synonym: salt solution. Specifically, an isotonic sodium chloride solution.; 0.85 to 0.9/100 ml water. (05 Mar 2000) |
| saline solution, hypertonic | Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g nacl in 100 ml purified water). (12 Dec 1998) |
| salt solution | A solution of any salt. Synonym: salt solution. Specifically, an isotonic sodium chloride solution.; 0.85 to 0.9/100 ml water. (05 Mar 2000) |
| saturated solution | A solution that contains all of a substance capable of dissolving; a solution of a substance in equilibrium with an excess undissolved substance. (05 Mar 2000) |
| hypertonic solution | Any solution which has a higher osmotic pressure than another solution (that is, has a higher concentration of solutes than another solution). A solution which contains a higher concentration of solutes than the cells that it is bathing, so that water is drawn out of the cells and into the solution by osmosis. A hypertonic solution is the opposite of a hypotonic solution. (09 Oct 1997) |
| hypotonic solution | <chemistry> Any solution which has a lower osmotic pressure than another solution (that is, has a lower concentration of solutes than another solution). A solution that contains a lower concentration of solutes than the cells that it is bathing, so that water flows into the cells from the solution by osmosis. Compare: hypertonic solution. (09 Oct 1997) |
| solution | <chemistry> Isotonic salt solution used for mammalian tissues, original version (for frog tissues) much modified and often used loosely to mean any physiological saline. (18 Nov 1997) |
| solution of contiguity | The breaking of contiguity; a dislocation or displacement of two normally contiguous parts. (05 Mar 2000) |
| solution of continuity | Division of bones or soft parts that are normally continuous, as by a fracture, a laceration, or an incision. Synonym: dieresis. (05 Mar 2000) |
| solution pressure | The force driving atoms or molecules to leave a solid particle and enter into solution (i.e., to dissolve). (05 Mar 2000) |
| standard solution | Standardised solution, a solution of known concentration, used as a standard of comparison or analysis. (05 Mar 2000) |
| Dakin's solution | A bactericidal wound irrigant. Synonym: Dakin's fluid. (05 Mar 2000) |
| supersaturated solution | A solution containing more of the solid than the liquid would ordinarily dissolve; it is made by heating the solvent when the substance is added, and on cooling the latter is retained without precipitation; addition of a crystal or solid of any kind usually results in precipitation of the excess solute, leaving a saturated solution.
