BASi Research Products will be closed on November 26th and 27th in observance of the Thanksgiving Holiday.

In Vivo Ultrafiltration Sampling Probes

In vivo ultrafiltration sampling probes use loops of membrane connected to a single collection tube. They are defined by the number of loops of membrane and the length of membrane in each loop. For example, the model UF-3-12 probe has 3 loops of membrane and each loop contains 12 cm of membrane. Use a probe like this if you want to get maximum flow and study extracellular analytes in a uniform tissue such as subcutaneous tissue. Since the membrane is formed into a loop, the loop length is half the membrane length. So in a UF-3-12 probe, the length of the loop is 6 cm. Other probe models are named in the same manner: UF-1-2 has one loop containing 2 cm of membrane, UF-3-8 has three loops each containing 8 cm of membrane, etc.

Do your probes need sterelized? We can do that! Contact us for more information. 

In Vivo Ultrafiltration Accessories

Several BASi® accessories can be used for in vivo ultrafiltration sampling. These include surgical supplies, animal caging systems, FEP tubing and tubing connectors, and the Vacuum Needle Holder. The Vacuum Needle Holder is a key convenience and safety item that we strongly recommend.
