isotope farm

[′ī·sə‚tōp ‚färm] (botany) A carbon-14 (14C) growth chamber, or greenhouse, arranged as a closed system in which plants can be grown in an atmosphere of carbon dioxide (CO2) containing 14C and thus become labeled with 14C; isotope farms also can be used with other materials, such as heavy water (D2O), phosphorus-35 (35P), and so forth, to produce biochemically labeled compounds.
