TS250III

1. 密封性能好,真空維持時間長:抽真空后三十天,真空度變化小于5%
1. Long time vacuum maintenance: Vacuum loss is less than 3% in 30 days.

2. 頂部裝有真空指示表,真空狀態可以隨時觀察
2. Real-time vacuum indication: vacuum gauge shows vacuum level in real time.

3. 容器不怕摔、不怕碰，可承受真空度劇烈變化，透明度好，重量輕
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. 用優質硅橡膠圈密封，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. 進、抽氣量微調:閥門為專用精密針閥,可微量調節進、抽氣量,避免吹損貯存物品和保護
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. 用快換接頭連接抽氣管與針閥，使得管道連接一插得
6. One step tubing connection: Fast and easy connection between valve and tubing is convenient and reliable.

7. 適用環境溫度：0℃-80℃。（可選的內部陶瓷隔板上可以放置加熱后的坩堝。）
7. Broad range of working temperature: 0℃～80℃
