    Precautions

    Safety 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)

    What material is the pressure vessel made of?
    The main body is constructed from high borosilicate glass, which features uniform wall thickness, uniform pipe diameter, and high transparency. It is paired with a PTFE threaded sealing cap that includes an O-ring.
    What is the maximum pressure limit for these glass vessels?
    Each pressure vessel undergoes individual pressure testing during production and can safely withstand up to 6 atmospheres of pressure.
    Can I use this pressure vessel inside a microwave?
    No. This product must not be used for microwave reactions. Microwaves cause the PTFE plug to expand rapidly when heated, which can cause the glass outer wall to crack.
    What safety measures should I follow during operation?
    You must implement dual safety protections. This includes always operating the vessel behind a safety barrier and conducting all reaction procedures inside a laboratory fume hood.
    What should I do if I notice scratches inside the tube?
    Be very careful not to scratch the inner wall of the glass tube during cleaning. If any scratches are detected, the structural integrity may be compromised; do not use the vessel for further pressure reactions.
    What specifications and volume capacities are available?
    The vessels are available in capacities ranging from 5ml to 100ml, with options for round bottom, flat bottom, and scaled/unscaled glass designs.
