Precautions
Safety & Operating Warning
Due to the special nature of this product and the condition of the product after use (such as scratches), the safety of this product and the resulting damage cannot be guaranteed. Dual safety protection measures must be used, including the use of safety barriers and operation inside a fume hood. This product cannot be used for microwave reactions, as microwaves can cause PTFE to expand upon heating, leading to glass cracking. At the same time, pay attention not to scratch the inner wall of the pressure resistant tube during cleaning. Once scratched, do not use it.
Frequently Asked Questions (FAQ)
Q:
What is the maximum pressure limit for these pressure vessels?
A: Each pressure vessel undergoes individual pressure testing at the factory and is designed to withstand up to 6 atmospheres of pressure, making it highly suitable for standard pressure reactions.
Q:
What materials are used to construct this pressure vessel?
A: The main body of the vessel is made from high borosilicate glass, which provides high transparency and uniform wall thickness. The sealing cap is constructed from PTFE (Teflon) and includes an O-ring for secure threaded sealing.
Q:
Can I use this glass pressure vessel in a microwave reactor?
A: No, this product cannot be used for microwave reactions. Microwaves can cause the PTFE sealing cap to expand rapidly upon heating, which can lead to glass cracking and hazardous failure.
Q:
What safety precautions should be taken during operation?
A: You must always implement dual safety protection measures, including operating the vessel behind a safety blast shield/barrier and strictly inside a properly ventilated laboratory fume hood.
Q:
How should I clean the pressure vessel, and when should it be retired?
A: Clean the vessel gently to avoid scratching the inner glass walls. If you notice any scratches, chips, or structural defects on the glass surface, discontinue use immediately as it compromises pressure safety.
Q:
Are there different bottom styles and capacity options available?
A: Yes, we offer both round bottom and flat bottom styles, available with or without graduated scales. Capacities range from 5ml up to 100ml.
