INTRUDUCING THE ULTIMATE IN DANDER, SUPWR UNSAFE, UNIQUE NEVER SEEN BEFORE FEATURES ON THIS luerFlex 5000ml filtering flask.If you don't die laughing at the craftsmanship, you might anyway.luerFlex 5000ml filtering flask.see picsthe neck opening varies on this luerFlex 5000ml filtering flask size and shape actually (round & oval). see pics.the glass thickness of this luerFlex 5000ml filtering flask varies, but is mostly pretty thick, except the bottom. that's thin as a coffee pot. see pics.the neck of this luerFlex 5000ml filtering flask is not level. see pics. not level means my funnel would be sitting at a severe angle. fascinating.see pics.the neck of this luerFlex 5000ml filtering flask has a variable protruding in and out bevel on almost half of it, the other portion is gently tapered other then the part that essentially missing.see pics.my FAVORITE feature of this craftsmanship-less luerFlex 5000ml filtering flask is how the neck is rough life sandpaper, it looks like the creator took a grinder to it to exentuate the partial bevel on a portion of the neck of the luerFlex 5000ml filtering flask. its also got some kind of black junk in the sand paper section.see pics.this is the LOWEST QUALITY, CROOKED IN EVERYWAY, UNPROFESSIONAL PIECE OF JUNKMADE BY: luerFlex I'VE EVER SEEN. see pics.Zero craftsmanship luerFlex 5000ml filtering flaskZero pride of self. see pics.if you are willing to put 5000ml of something you value or that can harm you if the ultra thin bottomed luerFlex 5000ml/ 1 gallon filtering flask flask breaks.then this is the one for you.see pics.inside the luerFlex 5000ml filtering flask the is a glass dimple protruding into the flask, it's at least 1/8" long. see pics.how many people check the bottoms of your flasks? the last feature that I have discovered on this this luerFlex 5000ml filtering flask is the the bottom center is redicilasly thin. zoom into the last Pic and try to see the perimeter of the magnet and my finger. it's far thinner than the vacuum stem, which is a different measurement. perhaps take several measurements and average them for a nice snug vacuum fit.I wonder how many things I have in my lab that I can fill this luerFlex 5000ml filtering flask halfway up with, lift it by the neck and have the bottom remain in place. or worse, you tilt it to get your hand under it and BINGO!WHAT A JOKE!luerFlex 5000ml filtering flaskluerFlex 4000ml filtering flaskluerFlex 1 GALLON filtering flaskI am not impressed.I'll spread the word for you in an effort to reduce your chances of getting sued.
