GPV & SLA Ports - Our Tried & Tested Polysulfone Models

The model GPV was introduced to the animal research community in 1981 and was the first vascular access port available for use in preclinical research. It soon became apparent that a smaller access port was needed by researchers and so the SLA was introduced in 1986.

Model GPV – introduced in 1981

Use in large animal species – swine, sheep, large dogs.

Model SLA – a favorite since 1986

Use in smaller animal species – cats, rabbits, small dogs.
