、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。Thequantityofliquidnitrogenstoredinthedewarmaybemeasuredbyweighingorbyinsertingalevelgage,thinwoodenorbamboostickintothedewartoseetheheightofitsfrostedpart（i.e.theheightofliquidnitrogen）.Itisprohibitedtoinsertanyhollowpipeintothedewartopreventtheliquidnitrogenfromsquirtingout.Duringtheoperation,attentionmustbepaidtomakeupliquidnitrogeninthedewarintime.Theheightofliquidmustn'tbehigherthanthebottomofthenecktube.Pleaseconductgentlyandcarefullywhenputtinginandtakingoutthefrozenmatters.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0.808kg/L）,即可得出液氮吸收体吸附的液氮体积。Containerduringuse,usersneedtotestinordertoreplenishtheliquidnitrogenstorageinliquidnitrogen,accordingtothefollowingmethod:First,saidthecontainercoveringtheplug,withoutmentioningwhentheweightofthebarrelandfrozenitems（ifthelinerhasresidualliquidnitrogen,youneedtocompletelypouredweighing）,minusthetableacorrespondingcontaineremptyweight,thedifferenceisliquidnitrogenabsorberliquidnitrogenadsorbedweightdividedbytheweightoftheliquidnitrogendensity（theoreticalvalueof0.808kg/L）,canbederivedliquidnitrogenabsorptionofliquidnitrogenadsorbedvolume.容器如需清洗，先用中性洗涤剂洗刷，再用不高于50°C的温水冲洗干图图2净。洗后应使内胆干燥（最好采用热风吹干，其温度不高于50°C）并冷却至常温后，再充入液氮。Ifitisnecessarytocleanthedewars,thecleaningmustbedonewithaneutraldetergentandthenthecleaneddewarmustberinsedwithwarmwateratatemperaturenothigherthan50C.Aftercleaning,theinnervesselmustbedried(preferablybyblowingwarmgasatatemperaturenothigherthan50C)andcooledtotheambienttemperaturebeforefillingliquidnitrogen.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。Thedewarsmustbeplacedinacool,ventilatedanddryarea.Theymustbecheckedtoseeifanyfrostorcondensedwaterexistsonthelevelofliquidnitrogenandtheoutersurfaceofthedewarduringlong-periodstorage.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：Waystoopenandclosethecoverofdewars.Topreventaccidentlyopenofcover(unlocked)causedbyabnormalvaporizationandpumping,coverwithlockinourcompanyusesspecificself-lockdesign.Toopenandclosethecoverofdewars,pleasefollowtheoperations: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。Atthelockedplaceofthecover,useyourfinger(IndexandMiddle)toclasptheedgeofuppercoverandimposeappropriateforcetowardsoutsideforawhile,thenflipup(seediagram2),thecoverofdewarisopened.Toclosethecover,aslight"Clicking"meansthecoverisclosed,uppercoverandbasehasbeenself-locked提筒的正确提取方法。用手握住一个提筒的提勾，垂直向上提起约40〜80mm,然后将提勾旋转180°,再垂直向上将整个提筒从容器中提取出来（如图3）。按照前述办法，便可以一一将容器中的所有提筒提取出来。Waystogetcanisters.Holdacatchofthecanisterbyusinghandandliftupabout40〜80mmvertically,thenrotate180°andliftupvertically,thecanisterisgotoutofthedewar(seediagram3).Allofthecanisterscanbegotoutbyfollowingtheways.图316、注意事项禁止向容器内注入其它液体，以免造成液氮吸收体的吸附能力减弱或者丧失。Neverfilltapwaterorotherliquidintothecontainer,avoidthefunctionofAdsorberweakeningorlosing.容器在空置时，应盖上盖塞以免液氮吸收体吸收大气中的水分，造成液氮吸收体吸附能力降低。Whilethecontainerleavesunused,pleasecoverPlugtominimizethemoistureabsorbedfromatmosphereandreducetheabilityofabsorbingliquidnitrogen.尽量避免容器受到强烈的震动和撞击，以免造成容器损坏，导致真空度丧失。Keepthecontaineruprightatalltimesandavoidtippingover.Duringusingandtransportingthecontainer,protectthecontainerfromseverejoltingandimpactthatcouldresultinpartialorcompletelossofvacuum.若需清洁内胆，可通过反复倾倒容器，倒出其中的杂物；或者用吸尘器吸出内胆中的脏物，不能采用水清洗容器内胆。DonotcleanInnerVesselwithtapwateroranyotherliquid.Ifthecleaningisnecessary,pleasepourthecontaineragainandagaintoswillthesundriesoraspiratethesundrieswithdustcollectoronlywhenInnerVessel(LiquidNitrogenAdsorberincluded)isdry.使用时切勿划伤颈管管壁。NeckTubeisthegateofaccessingliquidnitrogenandmaterialsstored.NeverseratchthesurfaceofNeckTubeduringusingthecontainer.不允许随意对容器采取充气加压或者密封使用。Donotcoverorsealtheentranceopeningofanycontainer^vhichwillresuItinexcessivegaspressurethatcandamageorburstthecontainer.定期测量容器中液氮的贮量，并及时补充液氮，以确保生物样品的有效贮存。Checktheliquidlevelatregularintervals,andrefillliquidnitrogenintime(atleasttwiceaweek)toensuretoprotectthematerialsstoredeffectively.严禁打开容器真空封口接头，否则产品不能继续使用。DonotopenEvacuatingNozzleofthecontainer,asitisthekeyparttomaintaininterlayervacuum.Onceitisdestroyed,itwilldeteriorateinterlayervacuumandthecontainercannotbeusedanymore.本产品生产涉及多项专业技术，若出现质量问题，只能将容器返回本公司进行检查和维修。ThecontainerreferstomanyprofessionaItechniques,soafterthequalityproblemsappear,pleasereturnthecontainertoourcompanyforcheckandmaintenance.七、产品质量保证范围(QualityGuarantee)本公司生产的液氮生物容器产品在正常使用情况下，自用户收货之日算起，一年内如发现确因产品制造原因而影响使用的，按下述办法执行：Iftheliquidnitrogendewarproducedinourcompanyisoperatedcorrectly,mycompanyguaranteesthatwewillsolveanyproblemarisingfrominferiorfabricationofthedewauvithinoneyearcalculatedfromthedaywhentheuserreceivestheinferiorlymanufactureddewarasperthefollowingmanners:容器初次充注液氮时，如发现容器表面出现有大量冷凝水、结霜等异常现象，我公司负责免费维修或调换。Iftheoutersurfaceofthedewarisfoundtohaveagreatdealofcondensedwaterorfrostafteritisfilledwithliquidnitrogenforthefirsttime,ourcompanywillrepairorchangethedewarforfree.容器初次使用前进行测试时，如发现产品静态液氮保存期低于标准的规定，我公司负责免费维修或调换。Whenthedewaristestedbeforeusingforthefirsttime,ourcompanywillrepairorreplacethedewarforfreeifthestaticholdingtimeofliquidnitrogenisshorterthanthestipulatedtime.在一年内，当产品出现确属我公司制造上的质量问题，我公司负责对产品进行检查或维修。Withinoneyear,mycompanywillexamineorrepairthedewarduetotheinferiorfabricationquality.若需维修或调换，必须发运附件齐全的容器，以及编号相符的产品合格证、购物凭证复印件等回公司检查办理。Ifreparationorreplacementofthedewaroccurs,thedewarwillbeshippedbacktomycompanywithallthedocuments,includingthequalitycertificatewiththeco
