主要特點(diǎn):
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3%
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(tài)可以隨時觀察
2. Real-time vacuum indication: vacuum gauge meter 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.
