An integrated ELF magnetic‐field generator and incubator for long‐term in vitro studies

摘要

AbstractLong‐term studies of the effects of low‐frequency magnetic fields on cells in culture require an incubator that is free of contaminating magnetic fields and that provides automatic control of exposure duration, uniform applied fields, a uniform and well‐controlled environmental temperature, and high reliability of the total system. We describe a dual‐incubator system in which the enclosed solenoid of either unit can provide a sham exposure while the other generates a magnetic induction of up to 500 μT. Each solenoid‐incubator unit contains an enclosed rack that can hold as many as 140 petri dishes for culturing cells; each unit is heated radiantly by circulating warm water. Field‐exposure conditions and temperatures are continuously monitored and controlled by a microcomputer. © 1992 Wi
