Ukukhetha ilungeloityhubhu yenkcubekoibalulekile ekuqinisekiseni iimvavanyo eziphumeleleyo kwizicwangciso ezahlukeneyo zelebhu. Iityhubhu zenkcubeko zisetyenziselwa ukukhulisa i-microorganisms, iisampulu zevenkile, okanye zenze uhlalutyo lwe-biochemical. Ngoluhlu olubanzi olukhetho, kubalulekile ukuba uqonde iimfuno ezithile zesicelo sakho. Esi sikhokelo siza kuphonononga izinto eziphambili ekufuneka ziqwalaselwe xa ukhetha ityhubhu yenkcubeko, egxile kwiimpawu zoyilo, ukwakhiwa kwezinto, kunye nezicelo ezisebenzayo.

1. Uyilo lwentambo

Enye yeembono eziphambili xa ukhetha ityhubhu yenkcubeko yoyilo lwenkqubo yokuvala. Iityhubhu ezininzi zenkcubeko zibonisa uyilo olusezantsi loyilo, njengeI-13 mm okanye i-16 mm imisonto. Olu luyilo luhambelana neCAPS yeCAPS, ukuqinisekisa itywina elikhuselekileyo elithintela isampulu yongcoliseko kunye nokuphuma. I-CAPS yeplastiki yeplastiki iluncedo ngakumbi kuba zilungele ngokuqinileyo kwaye kulula ukusebenza nangaphantsi kweemeko ezinxunguphalisayo.

Izibonelelo:

Itywina elikhuselekileyo: ukuthintela ungcoliseko kunye nokuphulukana nempumlo.

Kulula ukuzisebenzisa: Yenza lula ukusebenza kwaye unciphise umngcipheko wokuchitheka.

Ukuhambelana: Isebenza ngezixhobo zemigangatho yelebhu kunye nokuvalwa.

2. Ukuqulunqwa kwezinto

Izinto zebhubhu yenkcubeko inefuthe elibonakalayo kwintsebenzo yalo kunye nokufaneleka kwesicelo esithile. Ezona zinto ziqhelekileyo zibandakanya:

Iglasi ye-borosililicate

I-Borossililicate iglasi kukhetho oluthandwayo lwee-tyup zenkcubeko ngenxa yepropathi yakhe ebalaseleyo:

Uzinzo lweekhemikhali: Iglasi ye-boroslilicate ixhaphake kakhulu kuhlaselo lweekhemikhali, lenza ilungele ukugcina uluhlu olubanzi lweenyibiliki kunye nokuhlawulwa ngaphandle komngcipheko wokukhuthaza ungcoliseko.

Ukunganyangeki kumaqondo obushushu aphezulu: Le glass inokumelana nobushushu obuphakamileyo, kuyenza ilungele iinkqubo zokuchithwa njengokuzenzekelayo njengokuzenzekelayo.

Ukunganyangeki kothusa lwe-thermal: Iglasi ye-borossililicate inokumelana neqondo lobushushu ngequbuliso ngaphandle kokuqhekeza okanye ukophula.

Ezi ndawo zenza ukuba iityhubhu ze-tuus zeglasi zilungele ngokukhethekileyo kwizicelo eMicrobiology, inkcubeko yezicubu, kunye nezinye iinkqubo zelebhu apho kuncitshiswe khona ukuphathwa kwemichiza.

Iityhubhu zeplastiki

Ngelixa iglasi inika izibonelelo ezininzi, iityhubhu zenkcubeko zeplastiki ezenziwe ngezinto ezinje ngePolypropylene okanye i-polystrene nazo zisetyenziswa ngokubanzi:

I-chatweight kwaye iqine: Iityhubhu zeplasitiki azinantsingiselo yokwahlula kune-tub yeglasi.

Iindleko: zihlala zifikeleleke ngakumbi kunezinketho zeglasi, zilungele ukusetyenziswa kwezicelo eziphezulu.

Iinketho ezinokubala: Iityhubhu ezininzi zeplastiki zenzelwe ukuba zilahlwe, zinciphise umngcipheko wokungcoliseka komnqamlezo.

Kubalulekile ukuba uqaphele, nangona kunjalo, iplastiki ayinakubonelela ngenqanaba elifanayo lokungaxhathisi leekhemikhali njengeglasi ye-borossilicate, ngakumbi kwiinyibilikisi.

I-3. Utyhafile

Enye into ebalulekileyo ekufuneka uyiqwalasele kukungafihli ityhubhu yenkcubeko. Umbala ocacileyo uvumela abaphandi ukuba babone ngokulula imeko yokukhula kwenkcubeko ngaphandle kokuvula ityhubhu. Eli nqaku libalulekile kwizicelo ze-microbiological apho umngcipheko wongcoliseko kufuneka uncitshiswe.

Izibonelelo:

Ukuhlolwa kokubonakalayo: Ukwazi ukujonga ukukhula kwe-rabial okanye ukwenziwa kwe-sediment ngexesha lokwenyani.

Ukuncitshiswa kokuPhathaka: Ukunciphisa isidingo sokuvula ityhubhu ukuze uhlolwe, emva koko ugcine ukungathobeli.

I-4. Ubungakanani kunye nobungakanani

Iityhubhu zenkcubeko ziza ngobukhulu obuhlukeneyo kunye namandla, zihlala zisusela kwi-5 ml ukuya kwi-50 ml okanye ngaphezulu. Xa ukhetha ityhubhu yenkcubeko, cinga ngezi zinto zilandelayo:

IIMFUNO ZAMAPHEPHA IIMPAWU: Qinisekisa ukuba amandla etyhubhu ahlangabezana neemfuno zakho zovavanyo. Iimvavanyo ezincinci ezincinci okanye ivolumu yesampulu yesampulu, ityhubhu encinci inokwanela.

Ukuqwalaselwa kwendawo: Qiniseka ukuba ityhubhu ekhethiweyo ihambelana nezixhobo zakho zelabhoratri, ezinjengeeracks okanye amavumba.

5. Ukuqwalaselwa okukhethekileyo

Izicelo ezahlukeneyo zelabhoratri zinokufuna iintlobo ezithile zeeTubs:

I-Microbiology

Kwizicelo zeMicrobiology, ezinjengesiko lebhacteria okanye ifungi:

Iityhubhu zeglasi zikhethiwe ngokuchasene nekhemikhali kunye nokukwazi ukumelana neenkqubo ze-sterilic.

Qinisekisa ukuba ii-tubes ukhetha inkqubo ekhuselekileyo yokuvalwa ukhusela ungcoliseko.

Inkcubeko yezicubu

Kwizicelo zenkcubeko yezixhobo:

Ukucaca okuphezulu kubalulekile ekujonganeni kokukhula kwefowuni.

Khetha i-tub yeglasi yeglasi ezizenzekelayo ezizenzekelayo zokugcina ukungasebenzi ngexesha lovavanyo.

Ukuvavanywa kokusingqongileyo

Ukuvavanywa kokusingqongileyo:

Khetha iityhubhu zenkcubeko ezinokumelana noluhlu olubanzi lweechemicals ezifumaneka emhlabeni okanye kwiisampulu zamanzi.

Ukuba ubunzima kunye nokuqhawula iinkxalabo ngexesha lomsebenzi wasentsimini, qwalasela iinketho zeplastiki.

Ukungasebenzi kunye nokuthintela ungcoliseko

Xa ujongana neesampulu zebhayiloji, ukugula kubalulekile. Khetha iityhubhu zenkcubeko ezibhalwe phantsi okanye ezizenzekelayo ukuqinisekisa ukuba aziyi kwazisa ungcoliseko kwiisampulu zakho. Ukongeza, qwalasela iityhubhu ezilahliweyo xa uphatha inkcubeko ebuthathaka ukunciphisa umngcipheko wongcoliseko.

Ukukhetha ityhubhu yenkcubeko efanelekileyo kuqwalaselwa ngenyameko kwizinto ezininzi, kubandakanya izinto zoyilo, ukwenziwa kwezinto ezibonakalayo, iimfuno zobungakanani, kunye neemfuno ezithile zesicelo. I-Borossililicate i-gub ye-Glasi inikezela uzinzo kwimichiza, ukuxhathisa ubushushu obuphezulu, kunye nokucaca, kubenza balungele izicelo ezahlukeneyo zelebhu. Ngeli xesha, iinketho zeplastiki zibonelela ngokufana ukukhanya kunye nokusebenza kweendleko zokwenza useto lokufaka.

Ngokuqonda ezi zinto ziphambili kwaye zilungelelanise iimfuno zakho zelebhu, unokukhetha ezona ntetho zifanelekileyo zenkcubeko ukomeleza iziphumo zakho zovavanyo ngelixa kuqinisekisa ukuqinisekiswa kwesampulu kunye nokhuseleko. Enoba uqhuba uphando lwe-Microbiological okanye uvavanyo lokusingqongileyo, ukutyala imali kwiityhubhu ezisemgangathweni kuya kuba negalelo elikhulu kwimpumelelo yomsebenzi wakho welebhu.

Ngolwazi oluthe kratya malunga neetyhubhu zovavanyo lwe-COD kunye nezicelo zazo kuhlalutyo lwamanzi, zibhekisa kweli nqaku:"Indlela i-COD ye-COD isetyenziswa ngayo kuhlalutyo lwamanzi."
