It clogged rather quickly filtering out lemon zest, I think I should have been using a permeable separation plate to make the entire area of the filter paper effective, so I'll attribute the fast clogging to user-error."
"Purchased for a science fair project."
"Good quality, and does the job used in a Buchner funnel for vacuum filtration."
"They work for our use very well."
"Love these bad boys, they don't let any of that crap you don't want in, o use more filters but these alone do the job."

"Glad I went with smaller version there was some distortion of the plunger under very high draw (vacuum) that may have been worse with the larger model."
"I also purchased a few Turkey Basters here on Amazon that basically do the same thing for pulling old brake fluid or power steering fluid out of master cyclinders or pump reservoirs to replace with new fluid."
"No problems, used it to suck the old oil out of my supercharger and it worked like a champ."
"This makes accurate measuring a little tricky to calculate... basically, you'd want to stop at 90ml, then clear the hose into the syringe to get you to about 100ml."
"I doubt the elastomer plunger gasket would be resistant to oil based fluids so be sure to avoid contact with the plunger and any such fluids and clean thoroughly immediately if you plan to re-use the syringe."
"I was using this syringe with plastic tube to transfer home made hot sauce in exact amounts into containers for family and friends."
"The hose DOES come off the syringe, which actually worked out, as I could empty the syringe without pulling the hose up from the bottom of the transmission."
