16mm chubu

Chikhalidwe chagalasiti agalasiti agalasi awa azitamati amapukutira cholimba kuti athe kupirira zolimba za labotale. Cholinga cha Screw chimapereka chisindikizo cha Airtight kuti chitetezeke ndi kuipitsidwa. Zowoneka bwino zagalasi zimalola kusanthula kosavuta kwa zitsanzo. Machubu amagwirizana ndi njira wamba monga centrifugation, makulidwe ndi zitsanzo zosungira. Amatha kuphatikizanso zikwangwani zomaliza maphunziro kuti zizipezeka molondola komanso chizindikiritso chosavuta.

Chingwe cha COD chimapangidwa molondola komanso moyenera m'maganizo. Imakhala ndi zomangamanga zolimba zomwe zitha kupirira zovuta za mankhwala a COD, kuphatikizapo kutentha kwambiri komanso kuwonekera kwa mankhwala osiyanasiyana.

Kuyesa kwa COD ndi chizindikiro chabwino cha zoipitsa zopangidwa mu madzi otayika mafakitale okhala ndi matchatchi ndi zitsulo zolemera. Kuyesa kwa COD kumangothandizira kuyankha mwachangu kusintha zinthu zovuta zovuta zisanachitike.

CUBE chumba yoperekedwa ndi Aijiren imagwiritsa ntchito galasi labwino kwambiri, lomwe limakhala ndi chilengedwe ndipo sichikukhudzana ndi ma reagents. Kudzera mwa kuyesa kwa aijiren code, nthawi yomwe imafunikira kuti muyeso wa nthawi yake uzifupika kwambiri, makamaka powunikira ndi kuchuluka kwa mindandanda, yomwe imachepetsa kwambiri ntchito.

Ndikofunika kudziwa kuti ngati combestosts couptetessssss amphamvu imakhala ndi sulufuric acid ndi mankhwala ena, ma reagents ayenera kusamala mosamala. Zinthu zomwe zili mu mapaipi ziyenera kutayidwa mogwirizana ndi zofunikira za olamulira. Machubu awa amatha kugwiritsidwa ntchito kamodzi ndipo sangagwiridwenso ntchito.

Ndi mayeso a kachizono couiren code, wogwiritsa ntchito aliyense amatha kupezeka mosavuta komanso mosavuta. Nthawi yofunikira kuti muyeso muyeso zimafupikitsidwa kwambiri, makamaka kwa kusanthula kokhazikika ndi mndandanda, pomwe mukuchepetsa ntchito.

Chubu cha COD chomwe chimapangidwa ndi Aijiren ali ndi ma 10ml, 12ml, ndi 15ml. The Callaber ndi 16mm. Nthawi zambiri imagwiritsidwa ntchito poyesa madzi abwino ndipo imakhala ndi ma reagent amadzimadzi. Amagwiritsidwa ntchito kwambiri pamakampani a petroleum ndi kusanthula kwa mankhwala.

Kufunikira kwamankhwala kwa oxygen ndi mayeso ofunikira pakuwunika mtundu wa ma eyents ndi madzi otaya asanadutse. Mayeso a oxygen amafunikira (cod) amalosera za oxygen zofunikira ndipo amagwiritsidwa ntchito powunikira ndi kuwongolera zomwe zimachotsa ndalama, komanso kuwunika kasamalidwe ka mankhwala. Zovuta za kutulutsa kwamadzi kapena kuwononga madzi pa kulandira madzi kumanenedweratu chifukwa cha kufunafuna kwake kwa oxygen. Izi ndichifukwa choti kuchotsedwa kwa oxygen kuchokera ku madzi achilengedwe kumachepetsa kuthekera kwa moyo wam'madzi. Chiyeso cha COD chimachitika ngati chizolowezi cha ma labotore ogwiritsa ntchito zamadzi ndi makampani opanga mafakitale.

Ndi mayeso a kachizono couiren code, wogwiritsa ntchito aliyense amatha kupezeka mosavuta komanso mosavuta.
Nthawi yofunikira kuti muyeso muyeso zimafupikitsidwa kwambiri, makamaka pakuwunika ndi kuchuluka kwa mindandanda, ndikuchepetsa mphamvu.
Chubu choyesera cha cod chili ndi deto lokhazikika la regin. Chifukwa chake, kufufuza mopitirira kwamankhwala kwambiri kumapeweka ndipo chitetezo chantchito chimakhala bwino.

Tsatanetsatane wa mankhwala oxygen akufuna kuyesa:

2ML ya madzi kapena santeji ya Watse imawonjezeredwa ku chubu cha 16mmm miyambo yokhala ndi chimbudzi komanso chothandizira. Chubu chimasungidwa ndi polypropylene, ptfe yokhazikika ndikuwotcha mu digishi ya block ku 150C kwa maola awiri. Christovale ya lalanje ya lalanje imachepetsedwa ku chromishish yobiriwira. Mitundu yowunikira ya njira yoperewera ndi 5-160ppm (yoyesedwa pa 420nm).

Kuti mugwiritse ntchito chotenthetsera digito cha mayeso a cod, ikani kutentha pa chiwonetsero cha digito mpaka 150 ° C. Popanda ku akaunti yake iyenera kukhazikitsidwa pamtunda wapamwamba kwambiri kuposa momwe zafotokozedwera pamene izi zingayambitse chiwopsezo kudzera mu machubu a cood.

Oyenera ma cossimeter ndi kuyesa kits pamsika
Komanso oyeneranso kupangira zida
Mbale zosindikizidwa zotsekemera zokhala ndi zotsekemera
Kwezani moyo wa alumali kwa zaka zisanu
Ogwiritsidwa ntchito kumadzi am'madzi am'madzi; madzi otayika a mafakitale ndi njira yowongolera; Kuyesedwa kwa Madzi

Mayeso a chubu pakusanthula kwa Photometric amachititsa kuti ayambe kugwirana mosavuta ndipo chifukwa chake ndi chisankho choyambirira chofuna kuchita zinthu, kuwunika kwantchito. Pamwamba kwambiri molondola komanso molondola zimaperekedwa chifukwa cha kuchuluka kwa zotsatira za ma reagents oyambira mu 16mm cuvette ndi zowonjezera zowonjezera.

Aileriren amagwiritsa ntchito zida zapamwamba kwambiri kuti apange 16mm kuyesa chubu cha kusanthula kwamadzi. Kukhuta kwa Makasitomala ndi matamando apangitsa kuti chimodzi mwazomwe zimagwiritsidwa ntchito mosiyanasiyana opanga Southern China. Choyamba, Airiren adzagwira cholinga choyambirira kuti atsimikizire mtundu wa 16mm kuyesa kuti musanthule madzi.
