MASKIS Polycarbonate Vacuum Desiccator, Lab Vacuum Desiccator, With Negative Pressure Plus Air Meter and 150mm Double Valve, Vacuum Dryer Jar for Laboratory Research Vacuum Drying Storage

Long Storage Time: 30 days after vacuuming, the degree of vacuum changes less than 6%. Dry storage under vacuum can greatly extend the storage time. High-Quality Material: Lab vacuum dryer is made of polycarbonate, suitable for working temperature -25℃～120℃, with high strength and high transparency, it is not easy to crack, and it is convenient to observe the storage state of the internal items at any time. Good Sealing Performance: The transparent vacuum desiccator jar allows for easy to monitor of the drying process, making it a practical tool for any laboratory setting. High-quality silicone rubber O-ring seals between the upper and lower parts of the vessel, better sealing performance. Easy Operation：The valve is a special precision needle valve, which can adjust the intake air volume in a small amount. The exhaust pipe and the needle valve are connected with a quick-change joint. Apply To: Deliquescence deterioration reagents, precision metal parts, cameras, microscope lenses, glassware, etc. that require constant weight weighing in laboratory experiments. Make drying and storage containers. He is the right-hand man in the laboratory.
