Description
The Space Odyssey 6″ downstem is a solid replacement or upgrade piece built to pair with Space Odyssey beakers. At 6 inches with a 19mm joint, it fits the MK-1003 and MK-1034 models perfectly. The clear borosilicate glass is thick at 3mm, so it handles regular use without feeling fragile. This is the 2.0 version, refined since its October 2022 release. If you’re looking to swap out a worn downstem or just want a backup, this one delivers straightforward functionality.
Highlights:
- 6 inches long with 19mm joint size
- 3mm thick borosilicate glass
- Compatible with MK-1003 and MK-1034 Space Odyssey beakers
- Clear glass construction
- Version 2.0 design
- Intended for legal use only
Keep one on hand so you’re never stuck with a broken downstem.
*Per industry standard, length is measured from the bottom of the frosted joint to the tip of the downstem — not the overall end-to-end length of the piece. See our Downstem Measuring Guide for details.*
