okay guys.
if whatman filters are for single use only then, is it still okay to pull the syringe in and out (b/c i'm trying to put 40cc of oil solution into a vial using a 10cc syringe) so therefore i'd have to reload to solution 4 times to the whatman filter? is it still okay? is that still considered 'single' use?
just checkin guys.
