YDS-series products are mainly made up of outer shell, inner ve ssel, neck tube, multi-layer isolating material and canisters. (frag.1) dry shipper series also include liquid nitrogen absorbent. (frag . 2)1. 容器外壳、内胆采用铝合金板制作，具有重量轻、低温下强度高、耐腐蚀等特点。
The outer shell and inner vessel are made of the aluminum alloy plate featuring light weight, high cryogenic strength and corrosion resistance.2. 颈管采用玻璃钢制作，具有机械强度高、导热系数小等特点。
The neck tube is made of glass-fiber reinforced plastics featuring of high mechanical strength and low heat conductivity.3. 多层绝热体采用反射性能特别优良的铝箔为反射屏，采用导热系数小，放气速率低的材料为隔热材料，以减少热辐射。
The multi-layer insulation is composed of the reflecting screen of aluminum foils with high reflectivity and insulation material with low heat conductivity and low gas-passing speed to reduce heat radiation.4. 容器外壳与内胆间的夹层为高真空状态，以防止气体的热对流，并采用在低温状态下吸附量大的吸附剂，以保证容器的性能长期稳定可靠，产品寿命不低于5年。
The jacket between the outer shell and inner vessel is of high vacuum to prevent thermal convection. Moreover, an adsorbent with a high adsorbing capacity at the cryogenic temperature is used to ensure the long-term stable and reliable performance of the dewar with more than five-year life service.5. 航空运输型液氮生物容器中先进的液氮吸收体，可大量吸附液氮并防水、防潮。
当向容器中注入液氮时，液氮吸收体便充分吸附液氮，通过液氮吸收体吸附的液氮自然挥发形成氮气，使内胆中的温度在一定时期内始终保持在–150 ℃以下，保存的生物样品便可在冷冻和干爽状态下储存或安全地进行远距离运输，即使在运输途中容器倾倒，也不会有液氮流出。
While filling liquid nitrogen, Liquid Nitrogen Adsorber adsorbs and stores liquid nitrogen. Poring excessive liquid nitrogen from the container, nitrogen gas evaporated from liquid nitrogen in LiquidNitrogen Adsorber can maintain the temperature of Inner Vessel under-150℃for a certain period, it is suitable for long-distance transportation for liquid nitrogen stored or biological specimen stored, especially for air transportation. Even if the container is turned over, liquid nitrogen never spills out.六、产品使用须知(Notice)1. 用户使用产品前，应开箱检查产品外观质量，如发现容器外观有缺陷，在收到产品后5个工作日内，将此信息返回我公司（联系方式见封底）。
