Innovative drug infusion technology for laboratory animals.

Application of iPRECIO®

Tabular highlights gives a high level view of how iPRECIO pumps were used/programmed in selected scientific publications in Applications Examples eBook. For more detailed view, refer eBook and publications . In e-book for example, Research Application 1 (RA1) on page 5 & 6 of eBook is on row 1 of Tabular highlights – Chavan et al. The protocol is once a day infusion. RA2 on pages 7 & 8 (row 2 Kroon et al) has a 3 day stop prior to start of infusion of Nicotinic acid with the animal in the metabolic cage all of the time of the infusion protocol.
