We can build your catheters so you can concentrate on more important things! Purchase our species and access site specific catheters or allow us to reproduce your custom design and ship it to you pre-sterilized. Catheters used for dosing or collecting samples from rodents vary depending on the size of the animal and the site of access. SAI has taken the 'trial and error' out of the catheter selection process by developing catheters that are both site and animal specific. We have catheters readily available for the more common applications. Since our catheters are constructed by hand, customization is both simple and economical. Prototypes are often available next day!
