Vacuum Degassing Chamber, Glass Vacuum Chamber, with Stainless Steel Vacuum Gauge, for Lab Sample Preservation, Chemical/Biological Specimen Storage

Product Specifications: - Model with negative pressure gauge: Includes negative pressure monitoring gauge, supports -0.1MPa negative pressure, maintains pressure ≤-0.06MPa for 72 hours, equipped with straight-handle needle valve switch (vacuum pump required). - Compatible Equipment: Can only be filled with an air pump (inlet only, no air inlet, cannot be filled into the canister). Material: Glass 500ml: Inner diameter 65mm / Outer diameter 100mm Package includes: Main unit *1

• 【Easy Operation】: Employs a straight-handle needle valve switch for precise gas flow rate adjustment. The needle valve has excellent sealing performance, effectively preventing leakage. The vacuum container is compact and easy to carry (vacuum pump required).
• 【Safe Use Guarantee】: The storage container is designed specifically for gas pump intake, equipped with only one intake valve interface, no air inlet, and must not be filled with gas.
• 【Precise Negative Pressure Monitoring】: Equipped with a vacuum gauge, the head can achieve a high negative pressure of -0.1MPa, with clear and intuitive dial readings; pressure maintenance performance ensures the pressure remains stable below -0.06MPa for 72 hours.
• 【Applicable Scenarios】: For storing or carrying easily oxidizable samples, while strictly adhering to safety guidelines: Do not pressurize, do not add liquids, do not heat, and do not freeze or refrigerate.
• Glass Material Offers Good Light Transmission, Facilitating Observation of Internal Medium Status, Combining Practicality and Ease of Operation.
