I need to process a large number of 100ml samples through two sets of filters (0.3 and 0.22 micron) and save both filters and the filtrate.

While I could do this iteratively with a vacuum or syringe filter set-up, I would if possible like to use an inline double filtration manifold, or something similar.

However, I am unable to find the appropriate equipment to set this up.

Does anyone have any recommendations where I might find the parts or manifold to create this set-up?

Thank you in advance for your time and advice.
