There seem to be several different items here. Where did you get them and were they part of a set?

First reaction is that they seem to be silvered. Is that right? And could they be double-walled? They remind me of double-walled vacuum flasks used to handle things like liquid nitrogen. Those are silvered, to reduce heat transmission by thermal radiation. I see the spherical one has ground glass joints at either end.

Also these pictures are very poorly lit. Can you not illuminate them with daylight instead of a computer monitor?

Thank you for your reply !! To your first question these were all purchased in an online auction and essentially came with what you see with two platforms (one white one with smoked plexiglass) and three glass pieces which like you said appear to be silvered kind of what those coffee thermoses look like and yes they are doubled walled with aluminum Pyrex cast flange fasteners and  brass bottom plates to fasten down with and a rubber gasket  !! The dimensions are as follows  :   Tall double walled with small nipple glass is 28" H x 5" L x 5" W   :  Tall double walled large nipple glass is 30" H x 5"L x 5:W and the round sphere is roughly 7" in Diameter with one extension at 5 1/2" L with two open nipples and one extension at 4" L with one open nipple   Also i do not know if they were part of a set or not but am assuming they are !!!  I have enclosed some other pictures with the best lighting i can give you at the moment as i hope they will assist you in determining your opinion as what these could have been used for as several opinions would be greatly appreciated for future reference and information !!  Also the other big question i have is do these items have any money value or are they just considered junk and common and not worth pursuing for for those reasons or more of a good item but just to the right person ?   Any info would be greatly appreciated as you seem to have common knowledge of these items as i'm in the dark myself and have the slightest clue other than what info is given to me !!!  Anyways look forward to hearing your input and have a good one !!!   James T.

The metal flanges and overall size suggest a commercial setup of some kind. I'm wondering if, as an alternative to handling materials at low temperatures, e.g. liquified gases, it is possible this was designed for some sort of biological growth process requiring close control of temperature. But I am speculating wildly and have no more to offer, I'm afraid.

You need to find a good forensics chemist who can tell you what was in the flasks, or what the residues contain.

I'd say they will want access to a gas chromatograph.
