Ace Glass Heavy Wall Pressure Vessel 9 ml 19 mm OD 10.2 cm Length #7 Lot of 2 Vessels
The Ace Glass 8648-42 is a heavy-wall glass pressure tube designed for high-pressure laboratory applications, such as polymerization, catalytic hydrogenation, and specialty organic synthesis. Part of the 8648 series, it is engineered for safety and performance under conditions that would cause standard laboratory glassware to fail.
Core Performance & Safety
The 8648-42 is built from heavy-wall borosilicate glass, which provides significant structural integrity and resistance to thermal shock.
- Pressure Rating: Rated for a maximum internal pressure of 150 psi (approx. 10.3 bar).
- Temperature Limit: Capable of withstanding temperatures up to 120°C.
Operational Guidelines
-
Safety Shielding: Due to the inherent risks of glass under pressure, this vessel must always be used behind a safety shield or within a dedicated fume hood.
-
Inspection: Before every use, the tube must be inspected for "star cracks," deep scratches, or chips. Even minor surface defects can significantly lower the pressure rating and lead to catastrophic failure.
-
Cleaning: To maintain the structural integrity of the glass, avoid using abrasive brushes or strong alkaline cleaners (like base baths) which can thin the glass walls over time.
Used, in great condition.
