Bile Sampling Harness for Rats

Instech's dual channel VAH™ is ideally suited to bile collection. Install the harness at the same time that catheters are placed in the bile duct and duodenum. No special occlusion catheters are needed. Attach a loop connector so that bile flow, now diverted through the harness, can resume during transport and rest.

To collect, simply connect a dual VAH tether. Choose one of four tether configurations depending on whether you intend to replace the sampled volumes with artificial bile, and whether you prefer tether-mounted collection to minimize mixing and improve time resolution. The configurations with tether-mounted collection allow for automated bile sampling using Instech's ABS2.

The bile harness is also available with one or two extra injection ports mounted on the harness wings for sampling or injection near the animal. For example, catheterize the bile duct, femoral vein and jugular vein then connect this quad port harness for simultaneous bile sampling, infusion and blood sampling.

The older CIH-based bile reservoir harnesses are still available.
