Cod test tubes

Yakakwira-mhando cod bvunzo tubes zvinowanzogadzirwa ne5,0 borosilrate girazi, iyo ine simba rekupokana nekuparadza kwekutya uye kurema kwemakemikari. Iyo yakanaka cod test tube inofanirwa kunge iri nyore kushandisa, nyore kupinza uye kuderedza mhinduro, uye kwete kufungidzira.

COD bvunzo machubhu akasarudzika akagadzirwa girazi magirazi anoshandiswa muCOD ongorora maitiro. Aya machubhu ane huwandu hunozivikanwa hwe potasasum dichromate (iyo oxidizing mumiririri) uye sulfutic acid, pamwe neyechina. Zvinhu zvakakosha zve

COD Test Tubes inosanganisira:

Kugona: 10 mL, ine huwandu hwepamusoro hwe12 ml

Kureba: 10 × 0.02 cm

DIAMETER: 1.58 × 0.02 cm

Mutsipa wemukati diameter: 0.95 ± 0.02 cm

Mutsipa wekunze Diameter: 1.50 × 0.02 cm

Iyo yakakwirira yegirazi yegirazi mhando inosimbisa chaiyo colorimetric kuongororwa kweiyo cod mhinduro.

COD bvunzo maitiro

The the16mm cod bvunzoMaitiro anosanganisira kutevera matanho:

1. Mvura kana tsvina yemvura

3. Munguva yekudzidzira maitiro, iyo organic nyaya iri mumuenzaniso ndeye complised ne potassium Dichromate, ichidzora kune greenish trevalent chrompound.

Yakadzika Range (5-150 PPM): Yakayerwa pa420 NM

Yakakwira Range (20-1500 PPM): Yakayerwa pa620 NM

Unoda kuziva zvakawanda nezve cod test tube, ndapota tarisa chinyorwa ichi: COD bvunzo tube ne pp screw cap yekuongorora kwemvura

Sampule Kugadzirira uye Kubata

Mvura uye seyakaona samples inogona kunge iine zvisina musoro kana chidimbu chinhu. Samples dzakadaro dzinogona kuve dzakarukwa ne blender usati waedza kuvandudza kurongeka uye kudzokorora. Iyo huwandu hwemvura inodiwa kuti ubvise sampu inoenderana neye cod renji yeiyo bvunzo tube.

Cod lids uye application

Cod test tubesinowanikwa mumagariro akasiyana kuti ugone kutarisisa akasiyana siyana muenzaniso:

Yakakwira Range: 20-1500 PPM

Aya marangi akakodzera kuongorora akasiyana siyana masampuli emvura, kusanganisira:

a. Mvura mitsara yekurapwa

b. Mvura yakatsvuka kubva kuindasitiri uye masisitimu emari

c. Effluceents kubva kumaronda ekurapa kurapwa zvirimwa

d. Pamusoro pemvura uye pasi pevhu

Nekushandisa zvakakodzeraCod test tubeRange zvakavakirwa pane inotarisirwa cod cold

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