Electronic pest control. Electronic pest control is the name given to the use of any of the several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects. Since these devices are not regulated under the Federal Insecticide, Fungicide, and Rodenticide Act in the United States, the EPA does not require the same kind of efficacy testing that it does for chemical pesticides.
Laboratory Centrifuges. A centrifuge is a laboratory device that is used for the separation of fluids, gas or liquid, based on density.Separation is achieved by spinning a vessel containing material at high speed; the centrifugal force pushes heavier materials to the outside of the vessel.aboratory Centrifuges.

It is widely known that the IR-1 centrifuge, based on the Pakistani centrifuge called the P1, is not a reliable centrifuge. The P1 centrifuge was derived from a Dutch design that also suffered excessive machine breakage. The new performance data suggests that Iran has not succeeded in overcoming these design problems.igure 1 summarizes this discussion, showing centrifuge trends since the beginning of operations at the FEP, with the dark green bar indicating the number of centrifuges being fed with uranium hexafluoride, and the light green bar displaying the number of centrifuges installed.
