Sample Filtration

Vision® AutoFilter Changer

The Vision AutoFilter Changer automatically introduces 25 mm syringe filters into the fluidic path of your dissolution samples. Designed as a seamless addition to Hanson’s Vision® family of quality test instruments, the Vision AutoFilter Changer brings a new approach to automated filtration by giving you the power to determine the life of your filters.


Rather than discard filters after one-time use, the Vision AutoFilter Changer enables you to automatically introduce filters to the fluidic path, remove them if desired, return them back into position, or completely discard them, all of which is programmable. There are almost no limitations to the Vision AutoFilter Changer — you decide what works best for your method.
