Girazi rekuyedza chubhu chigaba chine cylindrical chakagadzirwa negirazi chinowanzo shandiswa mumarabhoritari esainzi kubata, kusanganisa, uye kudziyisa huwandu hudiki hwemvura kana yakasimba zvinhu. Machubhu ekuyedza anowanzo kuvhurika kune imwe mugumo uye ane pasi rakatenderedzwa kana kuti rakatsva zvishoma. Iwo anouya muhukuru hwakasiyana, kubva pamasendimita mashoma kusvika kune akati wandei masendimita pakureba.

Test Tube izwi rinogona kureva zvinhu zvakasiyana zvichienderana nemamiriro ezvinhu. Mumamiriro ezvesainzi, chubhu yebvunzo igirazi recylindrical kana chubhu yepurasitiki inoshandiswa kubata nekusanganisa zvinyoro zvishoma panguva yekuyedza mumarabhoritari. Inowanzoshandiswa mumakemikari, biology, uye mamwe maitiro esainzi.

Iyo yakashandiswa COD Tubetests ine yakasimba sulfuric acid uye mamwe makemikari, saka reagents inofanirwa kubatwa nemazvo. Zviri mupombi zvinofanira kuraswa maererano nezvinodiwa nevakuru venzvimbo.

Muedzo weChemical Oxygen Demand (COD) unoshandiswa zvakanyanya sechiyero chekusvibiswa kwehupenyu kuburikidza nekuona huwandu hweokisijeni hunodiwa pakuita oxidation yemhando dzakaderedzwa dzinosanganisira organic matter, mumucherechedzo wemvura uchishandisa imwe oxidizing agent, tembiricha uye kuderedza nguva. Kuyedzwa kweCOD chiratidzo chirinani chekusvibisa organic mumvura yetsvina yemaindasitiri ine cyanides uye zvinorema simbi. Kuyedzwa kweCOD kunopa mhinduro nekukurumidza kune shanduko yemamiriro ezvinhu asati atanga matambudziko akakomba. Lovibond's COD vials inoenderana neBOTH Lovibond uye Hach® colorimeters.

Muyedzo iyi reagent isina chinhu inoshandiswa pachinzvimbo chemvura yakajairwa isina chinhu inotaurwa mune yakajairika photometer yekushandisa mirayiridzo. Iyo reagent isina chinhu inogadzirwa nekuwedzera deionised kana distilled mvura kune reagent chubhu uye ipapo kugaya chubhu nenzira yakafanana neyeyemvura sampuli.

Zvakakosha kuziva kuti kana COD Tubetests yakashandiswa iine yakasimba sulfuric acid uye mamwe makemikari, reagents inofanira kubatwa zvakanyatsonaka. Zvinhu zviri mupombi zvinofanira kuraswa maererano nezvinodiwa nevakuru venzvimbo. Aya machubhu anogona kushandiswa kamwe chete uye haagone kushandiswa zvakare.
Izvo hazvifanirwe kugadzirira reagent isina chinhu pese panoitwa bvunzo. Iyo reagent isina chubhu inogona kugadzirirwa vhiki nevhiki uye inoshandiswa kakawanda nemasampuli ese akagadzirwa kubva kune imwechete batch reagent machubhu. Iyo reagent isina chinhu inofanira kuchengetwa murima pakati pekushandisa.

Iyo 16mm COD Test Tube inogadzirwa naAijiren inonyanya kushandiswa kuongorora kemikari murabhoritari. Aijiren anotenda kuti COD Test Tube inoda zvigadzirwa zvemhando yepamusoro uye tekinoroji yepamberi kuti ipedze kugadzirwa, saka Aijiren inotarisisa kugadzirwa kweCOD Test Tube. Aijiren anga ari murwi mumunda wechromatography consumables ane makore makumi maviri eruzivo rwekugadzira. Achiri kuchengetedza chinangwa chake chepakutanga uye anoisa kuvandudzwa kwehutano hwechigadzirwa pakutanga.

Iyi COD bvunzo chubhu yakagadzirwa nekurongeka uye kushanda mundangariro. Iyo inoratidzira chivakwa chakaomarara chinogona kumira kuomarara kwekuyedzwa kweCOD, kusanganisira kupisa kwakanyanya uye kuratidzwa kune akasiyana makemikari.

Mupfungwa yakakura, "Test Tube" inogona zvakare kureva chiteshi cheYouTube chinonzi "TestTube," inova sainzi yakakurumbira uye chiteshi chedzidzo chiri cheDiscovery Digital Networks. Iyo chiteshi inovhara akati wandei misoro, kusanganisira sainzi, tekinoroji, nhoroondo, uye tsika, uye inopa inodzidzisa uye inovaraidza mavhidhiyo kune vanoona.

Iyo COD chubhu yakapihwa naAijiren inoshandisa yemhando yepamusoro girazi, iyo inert yakanyanya uye isingaite nemareagents. Kuburikidza neAijiren COD tube test, nguva inodiwa yekuyera maitiro inopfupikiswa zvakanyanya, kunyanya kuongororwa kwakajairwa uye kuyerwa kwakatevedzana, izvo zvinoderedza zvakanyanya basa.

Kudiwa kwemakemikari okisijeni muyedzo wakakosha wekuongorora mhando yemvura inoyerera uye tsvina isati yaburitswa. Muedzo weChemical Oxygen Demand (COD) unofanotaura zvinodikanwa zveokisijeni mutsvina uye inoshandiswa pakutarisa nekudzora zvinobuda, uye kuongorora mashandiro echirimwa. Mhedzisiro yekuyerera kwetsvina kana tsvina yemvura pamvura inotambirwa inofanotaurwa nekudiwa kwayo kweokisijeni. Izvi zvinodaro nekuti kubviswa kweokisijeni kubva mumvura yakasikwa kunoderedza kugona kwayo kuchengetedza hupenyu hwemumvura. Kuedza kweCOD kunoitwa senguva dzose mumarabhoritari ezvemvura nemakambani emaindasitiri.
