Vision® AutoFilter™ Changer

The Vision AutoFilter is a filter changer that 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 equipment, the Vision AutoFilter brings a new approach to automated filter changing. It allows you to increase the life of your filters by allowing fluidic steps to take place with or without a filter.

There are almost no limitations to the Vision AutoFilter– you decide what works best for your method. Patent pending.
