| equivalence | <biochemistry, chemistry, immunology> The situation where two interacting species are present in concentrations just sufficient to produce occupation of all binding sites. Only used to describe high avidity interactions, especially the antibody/antigen interaction. (18 Nov 1997) |

| equivalence point | In a precipitin reaction, the zone in which neither antibody nor antigen is in excess. See: precipitation. Synonym: equivalence point. (05 Mar 2000) |
| equivalence zone | In a precipitin reaction, the zone in which neither antibody nor antigen is in excess. See: precipitation. Synonym: equivalence point. (05 Mar 2000) |

| equivalent extract | A fluidextract of the same strength, weight for weight, as the original drug. Synonym: valoid. (05 Mar 2000) |
| equivalent focal length | <microscopy> The focal length of the simple lens that has the same power as the compound lens. The stated focal lengths of microscope objectives are the equivalent focal length since their front and back focal lengths are very different. (05 Aug 1998) |
| equivalent form reliability | In psychology, the consistency of measurement based on the correlation between scores on two similar forms of the same test taken by the same individual. See: reliability coefficient. (05 Mar 2000) |
| equivalent temperature | The temperature of a thermally uniform enclosure in which, under still air conditions, a "sizable" black body loses heat at the same rate as in the nonuniform environment. (05 Mar 2000) |
| equivalent weight | The weight in grams of an element that combines with or replaces 1 gram of hydrogen, the atomic or molecular weight in grams of an atom or group of atoms involved in a chemical reaction divided by the number of electrons donated, taken up, or shared by the atom or group of atoms in the course of that reaction, the weight of a substance contained in 1 liter of 1 normal solution; a variant of. Synonym: combining weight, equivalent weight. (05 Mar 2000) |
