it is in a 1950's Maytag wringer washer with a plastic demo tub....The reason they used a columless pyrex agitator in this machine was so they prosepctive buyer could see the what waws underneath it....PAT COFFEY
Wouldn't PYrex glass be too fragile to use for an agitator?I would think it could be Lucite instead?The video clips of the machine are impressive-the "agitator" looks more like an "impellor" since it doesn't have a post.
The last operational demonstrator I remember wash full of water and poker chips. Quite an attention getter when you passed by the appliance department.
If Pyrex glass were fragile you would not be able to take it out of a freezer and put it right into a hot oven, nor would it be popular for use in labrotory setting either. Also I don't think as many pieces that have survived would still be around if it were fragile. PAT COFFEY[this post was last edited: 8/22/2010-14:14]
Pyrex glass-yes it can withstand sudden temp changes-to a point-but Don't DROP any Pyrex item-it will break-During my years in chemestry-have broken a few peices of Pyrex labware from drops.Like any glass it is fragile "mechanically"Maybe the "impellor" design of the Pyrex agitator gives it more mechanical strength.and if it was used in the clear drum with poker chips that shouldn't be a problem.
