Then the sales agency or distribution department shall solve the problem in accordance with the related clauses in the agreement2.液氮生物容器系列产品分贮存、运输两大类型。贮存型容器主要用于室内液氮和冷冻物品的静置贮存，不能作车载运输使用；为满足运输的使用条件，运输型容器作了专门的防震设计，该类容器除可静置贮存外，还可在充装液氮状态下作运输使用，但应避免碰撞和剧烈震动

26、。Liquid nitrogen container includes storage and transportation types.The storage dewar is mainly used for indoor static storage of liquid nitrogen and frozen goods. It is prohibited to use the storage dewar for transporting. To meet the requirements of transporting, the transporting dewar with speci

27、al anti-vibration design is used not only for static storage but also for transportation full of liquid nitrogen, but no bumping or sever vibration is permitted.3贮存型容器初次使用时，按如下步骤进行：Instruction for first time of using storage type:1）.若在室内对容器补充液氮，请注意要打开门窗操作，防止操作环境中严重缺氧。If the making-up of the liquid n

28、itrogen is conducted indoor, all the windows and doors must be opened to avoid the severe lack of oxygen to cause suffocation of the operator.2）. 贮存型新容器或已解冻复温的容器，在使用前必须先充入少量液氮预冷，接近热平衡（气化不剧烈）后再注满液氮。充装液氮时，宜用泵或长管漏斗，其充注管要插至接近容器底部，并须在容器口部留有空隙，让氮气排出。注入容器内的液氮液面高度不能超过颈管下端平面。操作中应避免人体与液氮接触，以免引起冻伤。New dewars o

29、r de-frosted dewars must be pre-cooled to reach the thermal balance (with no violent vaporization) before they are filled with liquid nitrogen. During filling liquid nitrogen, the pump or long-tube funnel is preferred for this purpose. The filling tube should reach near the bottom of the dewar with

30、a gap left at the dewar mouth as an outlet for gaseous nitrogen. The height of liquid nitrogen level filled in mustnt be higher than bottom of the neck tube. During the operation, caution must be taken against the contact of human body with the liquid nitrogen to avoid cold injuries.4.航运型容器初次使用时，按如下

31、步骤进行：Instruction for first time of usingdir shipper:1）向容器内注入液氮，液面高度达颈管底部；Fill the container to the bottom of Neck Tube and Liquid Nitrogen Absorber starts to absorb liquid nitrogen;2）12小时后，再向容器内注入液氮，液面高度达颈管底部；Fill the container to the bottom of Neck Tube for the second time 12 hours later to make li

32、quid nitrogen absorbed completely (to reach saturation);3）静止12小时后，才能将残余液氮倒出；After another 12 hours, Liquid Nitrogen Adsorber should be saturated (Complete absorption may take up to 24 hours);运输之前，应测试液氮吸收体是否已达饱和，按下述“容器中液氮贮量的测试”方法进行测算液氮吸收体吸附的液氮贮量，比较该值与表1对应的吸附容积数值，若两者偏差不大（由于大气压情况、制造误差，液氮吸收体的实际吸附能力与表1的理

33、论值可能有偏差），便可判定液氮吸收体已经饱和。反之，应再次向容器内注入液氮，2小时后，倒出残余液氮，即可使用。Prior to shipment, pour off the excess liquid nitrogen. If the container is just for storage, it is unnecessary to pour off the excess liquid nitrogen.In order to make Liquid Nitrogen Absorber reach saturation (to ensure the maximum liquid nitro

34、gen holding time), it is recommended to test if Liquid Nitrogen Absorber reaches saturation before the above step 4). The method is: calculating liquid nitrogen volume which Liquid Nitrogen Absorber adsorbs, and comparing with the value in Table 1. If the value calculated is as much as the value in

35、table 1, Liquid Nitrogen Absorber has reached saturation (The actual value is slightly different from the nominal value due to manufacturing tolerance). If not, refill liquid nitrogen to the bottom of Neck Tube. 2 hours later, Liquid Nitrogen Absorber will reach saturation.5. 在容器初次放入冷冻物品后的23个小时内，建议用

36、户落实专人，定时观察容器外表面是否出现冷凝水或有结霜现象，如出现这两种情况，表明容器的真空度已恶化，将引起容器内的液氮在很短的时间内挥发完，容器便不能正常使用。出现这种现象的概率虽然很小，有可能是由于未按产品要求进行装卸、运输所致，但为避免冷冻物品的损失，这种观察很有必要。Within 23 hours after the frozen goods are put into the dewar for the first time, a special person must be designated by the user to regularly observe whether ther

37、e is condensed water or frost on the outer shell. If there is condensed water or frost, it means that the vacuum of the dewar has been deteriorated, which will cause liquid nitrogen to evaporate completely in a very short time. In this case, the dewar cant work normally. The possibility of this kind

38、 of phenomenon is small. It may be caused by the improper unloading or transporting of the dewar. However, in order to avoid the loss of frozen matters, this kind of observation is very necessary.6.请注意，容器外壳已承受使用、运输环境的大气压压力，在使用或运输过程中，如发生严重碰撞或重压，将会使容器外壳表面发生凹陷，导致产品损坏或失效。Attention must be paid to the fa

39、ct that the outer shell of the dewar is under the atmospheric pressure in the transportation and operation, so if any serve bumping or heavy pressing occurs, the outer surface of the dewar will be dented to cause damage or ineffectiveness to the dewar.7. 容器为液氮贮存、运输而设计，严禁盛装液氧。The dewars are designed

40、for liquid nitrogen storage and transporting, please do not store liquid oxygen.8. 容器的内胆属常压工作状态，不允许随意采取充气加压或密封容器口的方法使用。The inner vessel generally works under the normal pressure and no pressurization is permitted at random and no sealing of the vessel mouth is allowed in operation.9. 颈管是液氮和冷冻物品进出的通道

41、，使用时切勿划伤管壁。The neck tube is the channel for liquid nitrogen and frozen matters and no scratch on the wall of the neck tube is allowed when using.10. 容器真空封口接头是保持容器夹层真空的关键部件，一旦受到破坏，将立即导致容器夹层真空恶化，产品不能继续使用，因此，用户不得擅自打开容器真空封口接头。The Evacuating Nozzle is important for protecting the interlayer vacuum of the

42、 dewar; Once damaged, the interlayer vacuum will deteriorate immediately and dewars cant work, so users mustnt open the Evacuating Nozzle privately.11. 容器中液氮贮量的测试Test of the quantity of liquid nitrogen in the container1）、贮存型容器中液氮贮量的测试检查容器内液氮贮存量，可使用称重法，也可采用液面尺、细木或竹杆插入液氮视其结霜高度（液面高度）的方法，切勿用空心管插入，以免液氮从管

43、内冲出飞溅伤人。使用中注意及时补充液氮，对容器补充液氮时，其液位的高度不得高于容器颈管的下端平面。操作及取放冷冻物品时，请注意要轻拿轻放。The quantity of liquid nitrogen stored in the dewar may be measured by weighing or by inserting a level gage, thin wooden or bamboo stick into thedewarto see the height of its frosted part (i.e. the height of liquid nitrogen). It i

44、s prohibited to insert any hollow pipe into the dewar to prevent the liquid nitrogen from squirting out. During the operation, attention must be paid to make up liquid nitrogen in the dewar in time. The height of liquid mustnt be higher than the bottom of the neck tube. Please conduct gently and car

45、efully when putting in and taking out the frozen matters.2）、容器在使用过程中，用户如需测试液氮贮量以便及时补充液氮，可按以下方法进行：先称出容器含盖塞、不含提筒和冷冻物品时的重量（若内胆中有残余液氮，则需完全倒出后称重），再减去表1中对应的容器空重，差值即为液氮吸收体所吸附的液氮重量，以该重量除以液氮密度（理论值为0.808 kg/L），即可得出液氮吸收体吸附的液氮体积。Container during use, users need to test in order to replenish the liquid nitrogen

46、storage in liquid nitrogen, according to the following method: First, said the container covering the plug, without mentioning when the weight of the barrel and frozen items (if the liner has residual liquid nitrogen, you need to completely poured weighing), minus the table a corresponding container

47、 empty weight, the difference is liquid nitrogen absorber liquid nitrogen adsorbed weight divided by the weight of the liquid nitrogen density (theoretical value of 0.808 kg / L), can be derived liquid nitrogen absorption of liquid nitrogen adsorbed volume.12. 容器如需清洗，先用中性洗涤剂洗刷，再用不高于50的温水冲洗干净。洗后应使内胆干

48、燥（最好采用热风吹干，其温度不高于50）并冷却至常温后，再充入液氮。If it is necessary to clean the dewars, the cleaning must be done with a neutral detergent and then the cleaned dewar must be rinsed with warm water at a temperature not higher than 50. After cleaning, the inner vessel must be dried (preferably by blowing warm gas a

49、t a temperature not higher than 50) and cooled to the ambient temperature before filling liquid nitrogen.13. 容器应放在阴凉、通风、干燥的环境中；长期贮存时应注意定时检查液面和容器外表面有无冷凝水和结霜现象。The dewars must be placed in a cool, ventilated and dry area. They must be checked to see if any frost or condensed water exists on the level

50、of liquid nitrogen and the outer surface of the dewar during long-period storage.14. 容器盖的开启、关闭方法。为防止非正常的振动、碰撞等原因造成容器盖（未加锁时）的意外开启，我公司产品配装的带锁扣的容器盖采用了独特的自锁结构设计。用户在开启、关闭容器盖时，应按如下方式操作：Ways to open and close the cover of dewars. To prevent accidently open of cover(unlocked) caused by abnormal vaporization

51、 and pumping, cover with lock in our company uses specific self-lock design. To open and close the cover of dewars, please follow the operations:在容器盖上锁处，伸入手指（食指和中指）扣住上盖边缘朝外施加并维持一定的力，然后向上翻转即可打开容器盖（如图2）。关闭容器盖时，当听见轻微“咔嚓”一声，表明容器盖的关闭已到位，上盖和底座之间已形成了自锁。At the locked place of the cover , use your finger(Ind
