The iPRECIO® infusion pump is designed for subcutaneous implantation in mice, rats and larger laboratory animals. Once implanted, animals are unrestrained and can move freely in their cages during drug infusion. Infection risk is reduced compared to tethered infusion models. Additionally, animals are likely to experience significantly less stress compared to conventional dosing methods. The iPRECIO® SMP-310R can be implanted subcutaneously in mices as small as 22 grams. The iPRECIO® SMP-200 pump can be implanted in 230 gram rats or larger animals.
