Roby 25
Roby 25 syringe filters for robotic systems were developed specifically for automated sample filtration systems. Whatman offers Roby syringe filters with various membranes. For difficult-to-filter samples, Roby syringe filters are also available with membranes plus an integral glass fiber prefilter.
The filter housing is made from mechanically stable polypropylene. The external geometry of the filter housing ensures simple and smooth filter transport from the storage turntable to the filtration site and easy filter changing.
