COD Test Tubes: Mirayiridzo & PreCCity Guide

Kuwedzeredzwa kweiyo yakawanda yekugaya chiridzwa pamusika kunoitwa muna 16mm, uye kushivirira kweganda regiredhiti ranyanyisa

Kureba kweIyo bvunzo tubeKazhinji 90, 100, 110, 125, 130, 150mm. Maererano neiyo yakasarudzika reagent ratios yeumwe neumwe mugadziri, kukwirira kwacho zvakare kwakasiyana. Pakati pavo, zvakanyanya kushandiswa ndeyekuti 100mm bvunzo tube.

COD bvunzo tubes zvinhu

Zvigadzirwa zveCod test tubeKazhinji zvinodzika borosilrate, kusarerekera kurongeka, uye borosilrate. Ivo vanogona kushandiswa kana pasina ruvara rwunodiwa. Kana mvura yemhando yekugaya uye colorimetry inodiwa, iyo yakasarudzwa zvinhu hazvirereke kuronga.

Kune matatu marudzi emidziyo yeiyo lid: White polypropylene imwe-nguva yekushandisa; yakajeka polycarbonate yekudzokororwa kushandiswa; dema phenolikhi resin yekudzokororwa kushandiswa kwemabhuru emibvunzo pamusoro 110mm.

Kuti uwane rumwe ruzivo nezve cod test tubes uye zvavanoshandisa mukuongororwa kwemvura, kureva chinyorwa ichi:"Maitiro ekuti iyo COD Test tube inoshandiswa mukuongorora kwemvura."

Diguession Tube Zvirango

1. Shandisa chirairo chekugaya chinoenderana nepasi pebhubhu. Round Bottoms inoenderana neyekutenderedza zera zera zvikepe, uye flat bottoms inoenderana neyekufa zera zera zera zviridzwa. Zvikasadaro, kupisa kusinga zivikanwe kuchaita kuti tube ibvise. Paunenge uchiisa iyo test tube, inofanira kuiswa zvishoma nezvishoma kuti udzivise kuputika yakakonzerwa nekurohwa kwechisimba kwekufa kwechigaro chechikepe chine gomba rekugaya. Maererano nechiitiko chekare, vamwe vanogaya machubhu vakaputika nekuda kwekushanda zvisina kunaka.

2 Mismatches haizo kusimbisa uye kusvetuka. Izvo zvinonyanya kuenderana nekuti inotsvedza kana ichipinza. Smooth uye yakatsetseka uye chivharo hachina kunyatso kukomberedzwa kuita zvinodiwa.

3. Ngwarira manyorerwo akawanda. Ma tubes uye machubhu achave nekukanda kana achikweva achipesana. Kuchenesa bhodhoro kuri nyore nyore kukonzera kukanda. Iyo mabviro ndiyo pfungwa isina kusimba yesimba rehubhu.

4. Ngwarira kushandisa mabhodhoro akakuvadzwa uye madhiri. Nekuda kwekupindira kwemanyorero panguva yekufambisa uye kugadzirwa, zvigadzirwa zvakadaro hazvigoneke. Usashandise mabhodhoro uye anovhiringidza nehurema.

5. Usagaya masampuli emvura zvakananga. Iwe unofanirwa kuve neanoenderana reagents. Iyo yekubikira yemvura yakaderera kwazvo. Iyo yakawanda mvura iripo, kuwanda kwekumanikidzwa mubhodhoro ichave, uye chivharo hachingakwanise kusimukira. Kana iwe uchida kugaya mamwe masampula emvura, ndapota shandisa zvakaoma uye zvakanyanya kupisa-kupokana nevharo.

6. Kutora kutsunga kweCoD ine sampuli yemvura semuenzaniso, kubva kune imwe nzira yekudziya yekudzora isati yasvika pakufa kwemvura, Naizvozvo, sampu yemvura inofanira kusanganisa kunyange usati wachera kuti udzivise kugaya kwekugezesa kubva pakuputika.

Kuenzanisa Kuchera

1. Zunza zvakanaka usati wamuenzanisa. Usati waisa iyo test tube mu photo, pukuta iyo test tube yakachena nejira rekutarisa.

2. Sarudza chishandiso chakasarudzika uye chishandiso che pipetting chine chikanganiso chidiki kuti udzivise zvimwe zvikanganiso zvinokonzerwa nebasa nemidziyo.

3. Kana paine chikwangwani, usabatanidza iyo scratch pamusoro neyekuenzanisa chinzvimbo.

4 Kana makumi maviri muzana emabhuru mune batch inodarika iyo yekukanganisa renji, iyo colorimetric machubhu eiyi batch haina kukodzera.

5. Ndokumbirawo ushandise mvura yakachena kuyedza iyo tube kukanganisa.

[Matipi eColuterimetric kuenzanisa]

Kana colorimetric enzanisa, usayedze imwe chete kona, nekuti zviri nyore kuve nezvakakanganisa mukukora uye kushoma kukosha, kana kungangoitika kuti pamusoro wauri kuyedzwa une mabvi kana guruva. Izvo zvakanaka kuti uedze zvikamu zvitatu neiyo imwechete tube. Kana kukosha kwenzvimbo nhatu dziri mukati me 0,005, shandisa izvi zvitatu kukosha kutora avhareji semhedzisiro yebvunzo. Izvi zvinodzivirira zvikanganiso zvinokonzerwa nekukanda uye kudzivisa kutora kukosha kwakanyanya kweiyo tube kukanganisa. Kana iyo yakafanana tube inotorwa kanopfuura ka6 times uye isingakwanise kuwana matatu ematatu mukati me 0,005, saka pane dambudziko neiyi tube (kusagadzikana hakuna kunaka).

Kunzwisisa kwakadzama kwekuti coD vials anoshanda mukuedzwa kwemvura, ndapota tarisa kuchinyorwa ichi:"Iyo inoshanda nheyo ye cod vial"
