1. 密封性能好,真空维持时间长:抽真空后三十天,真空度变化小于5%
1. Long time vacuum maintenance: Vacuum loss is less than 3% in 30 days.
2. 顶部装有真空指示表,真空状态可以随时观察
2. Real-time vacuum indication: vacuum gauge shows vacuum level in real time.
3. 容器不怕摔、不怕碰，可承受真空度剧烈变化，透明度好，重量轻
3. Robust, high optical clarity and light weighted: All contents can be easily viewed through the container(desiccator)'s clear polycarbonate top and bottom. This laboratory grade plastic material is strong and resistant to most common chemicals, sudden pressure change and cleans easily.
4. 用优质硅橡胶圈密封，不需要密封油脂
4. Oil-free sealing: Silicone O-ring allows good oil-free sealing. The all plastic construction ensures a clean chamber
5. 进、抽气量微调:阀门为专用精密针阀,可微量调节进、抽气量,避免吹损贮存物品和保护
真空表
5. Fine tuning of pumping and venting: Accurately controlled pumping and venting is allowed by niddle valve. Thus, turbulence caused by fast pumping and venting can be eliminated. Low pressure inert atmosphere storage can be also achieved.
6. 用快换接头连接抽气管与针阀，使得管道连接一插得
6. One step tubing connection: Fast and easy connection between valve and tubing is convenient and reliable.
7. 适用环境温度：0℃-80℃。（可选的内部陶瓷隔板上可以放置加热后的坩埚。）
7. Broad range of working temperature: 0℃～80℃
