The glass stem goes directly into the glass lined bowl, so any off gassing is not even an option.The DV was also not actually off gassing, I'll update that in the DV thread though.
Also, someone asked about the breakage possibility of the glass. Given that the entire bowl and stem is hugged by a silicone sleeve, breakage is unlikely as long as the stem is recessed, not to mention the glass is Pyrex, so pretty strong. Now if you happen to drop the unit while the stem is pulled out, of course it could break. The entire unit has the ability to be disassembled, so replacement pieces are available. The industry (you guys) have been asking for a pure GonG vapor path on a portable, so we listened and built this...but as with any materials there has to be some type of compromise.
When I get in the office in the am, I'll post some size specs. I wish I had good pictures of the unit, but we're all going to have to wait just a little while. We're still working on the outside aesthetics, so our testing samples aren't pretty enough to post just yet.
If anyone is attending Big or Champs in February, come by and see me and I'll show you the units personally
