CaptiVac Vacuum Collars 

For use with Captiva Filtration and 96-well Collection Plates and SPEC 96-well Plates, this patented vacuum collar is a completely transparent device that joins Captiva or SPEC plates directly onto our collection plate. The unique design of the Captiva collar forms a pre-set, pre-aligned vacuum seal between the filtration plate and the collection plate, which positions the outlet tips at a specified distance inside each well, so as to prevent cross contamination of samples.
