Update June 9, 2015
If your Vitamix is within Warranty period, they will supply you with the Revised Container..
No known Retail Vitamixes comes with the Revised Container, so you will still have to call them if you purchase from a brick-n-mortar.Ok.. So.. Way back in April of 2014, it was discovered that Vitamix blending blade-hubs shed black teflon particles INTO the mix.
97% of online users who saw the major threads over @ slickdeals reported black-dust-positive.
Today, I've received 2 replacement containers from Vitamix, under the promise that they are "FIXed" and black dust free.
I am happy to report that, this is INDEED the case.If you take a look at the pictures below.. The black seal ring is now made of a SOFT-er rubber material, and the central post makes direct contact with it.
The seal between the central post and the black ring, is done via what Vitamix will tell you is a FOOD-SAFE lubricant.
As you can see, this lubricant (white stuff around the ring) will get into your food, albeit, in small amounts.
There's no way to make this type of seal work without the lube, so, that's always how it's gonna be.
Originally there were 2 issues with the old hub.. the Original black cap was of a hard material, and would disintegrate upon use.
This was what caused the black specs to enter the blend.
The second issue was, the original blade hub, also allowed SOME lubricant to get into the mix. in the previous case, the lubricant was (black) and was visible during prolonged blends.
The new lubricant seems to be all White, which, means even if it got into your blend, it will be invisible.
With this new hub, Vitamix has rectified the Teflon-Black-dust situation, and took care of the aesthetic Black-lubricant situation.
