16mm White Screw Neck Caps with flat bottom Tube

Vula ishubhu lokuhlola le-COD, libambe nge-engeli bese wengeza kancane
2.0 mL of the pretreated sample solution from the reaction tube without mixing so that two separate layers
are formed.
Screw cap securely on to test tube, hold tube by the cap, place tube into the safety bottle and shake
(Caution, test tube becomes hot). Place tube into the heating block. Start heating programme.
Ngemva kwamahora angu-2 khipha ishubhu lokuhlola endaweni yokushisa, vumela ukuba liphole ekamelweni lokushisa futhi unyakazise kancane
several times.
Clean outside of test tube and measure.
Lungisa i-photometer ibe yiziro ngokusebenzisa inani elingenalutho elithi "NULL"

I-Aijiren isebenzisa izinto zokusetshenziswa zekhwalithi ephezulu ukwenza Ishubhu Lokuhlola elingu-16mm Lokuhlaziya Amanzi. Ukwaneliseka nokudumisa kwekhasimende kwenze i-Aijiren yaba ngenye yabakhiqizi abakhulu baselabhorethri abasebenzisekayo eningizimu yeChina. Okokuqala, i-Aijiren izogcina inhloso yokuqinisekisa ikhwalithi ye-16mm Test Tube Yokuhlaziya Amanzi.

Izitsha zengilazi ezikulungela, ezaziwa nangokuthi izitsha ezikulufa ezikulukulu noma izitsha ezingaphezulu kwezikulufu, iziqukathi ezincane ezenziwe ngengilazi ezinomshini wokuvala isikulufu. These vials are commonly used in laboratories and other scientific settings for the storage and transportation of liquid or powdered samples.

Ukuhlolwa kwe-Chemical Oxygen Demand (COD) kusetshenziswa kabanzi njengesilinganiso sokungcoliswa kwezinto eziphilayo ngokunquma inani le-oxygen edingekayo ukuze kufakwe i-oxidation yezinhlobo ezincishisiwe ezihlanganisa izinto eziphilayo, kusampula yamanzi kusetshenziswa i-oxidizing ejenti ethile, izinga lokushisa kanye nokunciphisa isikhathi. Ukuhlolwa kwe-COD kuyinkomba engcono kakhulu yokungcola kwemvelo emanzini angcolile ezimbonini aqukethe ama-cyanide nezinsimbi ezisindayo. Ukuhlolwa kwe-COD kunikeza impendulo esheshayo ezimeni ezishintshayo ngaphambi kokuba kuthuthuke izinkinga ezibucayi.

Isidingo somoya-mpilo wamakhemikhali siwukuhlola okubalulekile kokuhlola ikhwalithi yamanzi alahlwayo kanye namanzi angcolile ngaphambi kokuba akhishwe. Ukuhlolwa kweChemical Oxygen Demand (COD) kubikezela isidingo somoya-mpilo kumfucumfucu futhi isetshenziselwa ukuqapha nokulawula okuphumayo, kanye nokuhlola ukusebenza kwezitshalo zokwelashwa. Umthelela wokuchitheka kwamanzi angcolile noma angcolile emanzini atholwayo ubikezelwa ngesidingo sawo somoya-mpilo. Lokhu kungenxa yokuthi ukukhishwa komoya-mpilo emanzini emvelo kunciphisa amandla awo okulondoloza impilo yasemanzini. Ngakho-ke ukuhlolwa kwe-COD kwenziwa njengenjwayelo kumalabhorethri ezinsiza zamanzi nezinkampani zezimboni.

I-Aijiren Sample Storage Vial ivamise ukusetshenziselwa ukuhlaziya imvelo. Isitsha Sengilazi Esicacile singabona kangcono isimo sesampula. I-Amber Glass Vial ingamelana nokukhanya kwe-ultraviolet futhi ivikele izingxenye zamakhemikhali kusampula ezizwela ukukhanya kwe-ultraviolet.

I-Aijiren ibambe iqhaza ekukhiqizeni ishubhu yokuhlola ye-COD ene-Caps iminyaka engaphezu kweshumi, sinolwazi olucebile ngokuphelele nezinqubo ezijwayelekile zokukhiqiza ishubhu yokuhlola ye-COD enekepisi, futhi singaqinisekisa ikhwalithi ephezulu yeshubhu lokuhlola le-COD elikhiqizwa i-Aijiren ngentengo efanelekile.

Izitsha zesampula zokugcina zisetshenziswa kakhulu ekugcinweni kwesampula nasekuthuthweni.

Details of Chemical Oxygen Demand Test:

U-2mL wesampula wamanzi noma we-watse wengezwa eshubhuni yengilazi engu-16mm equkethe into evuselela ukugaya ukudla kanye ne-catalyst. Ishubhu imbozwe nge-polypropylene, ikepisi elayishiwe ye-PTFE futhi ishisiswe ku-block digester ku-150C amahora angu-2. I-chromium ye-Hexavalent ewolintshi yehliswa ibe yi-chromium e-trivalent eluhlaza okwesibhakabhaka. Ibanga lokuhlaziya lendlela ye-spectrophotometric ngu-5-150ppm (kukalwa ku-420nm).

Ukuhlolwa kwe-COD kunikeza impendulo esheshayo ezimeni ezishintshayo ngaphambi kokuba kuthuthuke izinkinga ezibucayi. Izitsha ze-COD zika-Lovibond ziyahambisana nama-colorimeter OKUMBILI we-Lovibond ne-Hach®.

Ukuhlola amanzi e-Total Organic Carbon (TOC) akusabalulekile embonini yezemvelo. Ngezindlela zakamuva ze-USP, i-TOC manje isiyinkinga yanoma iyiphi imboni esebenzisa Amanzi Ahlanzekile Namanzi Omjovo. Izitsha ze-TOC ze-Aijiren Low Level zihlanzwa ngokukhethekile futhi zipakishwe ukuze kwehlise i-TOC ibe amazinga aphansi kakhulu ngangokunokwenzeka, iqinisekisa isizinda esiphansi sokuhlolwa kwakho.

Ukuhlolwa kwe-tube kokuhlaziywa kwe-photometric kukholisa ngokuphathwa kwawo kalula ngakho-ke kuyinketho yokuqala yokuhlaziywa kwenqubo, ilabhorethri kanye nenqubo. Ubuningi bokunemba nokunemba kunikezwa emiphumeleni yokulinganisa ngenxa yama-reagents afakwe umthamo wangaphambilini ku-16mm cuvettes nama-reagents engeziwe.

I-Aijiren ibikhiqiza i-15-425 Screw Neck Storage Vial kusukela ngo-2009 futhi isineminyaka engaphezu kweshumi ilapho.Siyakwamukela ukuthengwa kweVial Eshibhile ye-Screw Neck Storage Vial, izitsha ze-PP, izitsha zechromatography kanye nesihlungi seSiringe. Thola i-15-425 Screw Neck Storage Vial enabakhiqizi bekepisi nabahlinzeki abavela eChina. Singumkhiqizi ochwepheshe we-15-425 Screw Neck Storage Vial.

I-15-425 Screw Sample Storage Vials eyenziwe ngengilazi ye-borosilicate yekhwalithi ephezulu yokushisisa noma i-autoclaving, i-syringe esheshayo ukufinyelela kuma-reagents avaliwe ngokuphelele namazinga. I-Aijiren Sample Storage Vials itholakala ngosayizi ababili wokugcina, ukufudumeza kanye ne-autoclaving.

TOC is the abbreviate by Total Organic Carbon. I-TOC Direct Method evela ku-Aijiren inikeza izindlela ezithembekile nezisebenzayo zezindawo zokuhlanza amanzi ukuze zivame ukukala ikhabhoni ephilayo ukuze kuthuthukiswe izinqubo zokwelashwa. Esikhundleni sokuthenga umhlaziyi we-TOC obizayo, ongokwesiko noma ukhiphe izinqumo ze-TOC elabhorethri yenkontileka, le ndlela inganikeza imiphumela ye-TOC - ngokunembile futhi engabizi - khona kanye endaweni yakho, futhi ngaphandle kwanoma iyiphi imfucuza eyingozi.

With the Aijiren COD tube test, each user can easily perform highly sensitive and accurate water detection.
Isikhathi esidingekayo senqubo yokulinganisa sifinyezwa kakhulu, ikakhulukazi ekuhlaziyweni okujwayelekile kanye nesilinganiso sochungechunge, kuyilapho kunciphisa kakhulu umsebenzi.
The COD Test tube contains a precise dose of reagent. Ngakho-ke, inani lamakhemikhali eleqile liyagwenywa futhi nokuphepha komsebenzi kuyathuthukiswa.

Kulokhu kuhlolwa kusetshenziswa i-reagent engenalutho esikhundleni sendawo evamile engenalutho yamanzi okukhulunywe ngayo emiyalweni evamile yokusebenza kwe-photometer. I-reagent blank ilungiswa ngokungeza amanzi akhishwe i-deionised noma a-distilled kushubhu le-reagent bese kugaywa ishubhu ngendlela efanayo neyesampula yamanzi.
Akudingekile ukulungisa i-reagent engenalutho njalo lapho ukuhlolwa kwenziwa. The reagent blank tube may be prepared weekly and used repeatedly with all samples prepared from the same batch of reagent tubes. The reagent blank should be stored in the dark between uses.

Isitsha Sokugcina Isampula esikhiqizwe i-Aijiren silungele ukuhlaziywa kwemvelo nokugcinwa kwamasampuli. I-15-425 inamandla amabili ahlukene, i-8ml ne-12ml, ifanele izinhlobo ezahlukene zamasampula.

I-Screw Glass Vials yiziqukathi ezincane eziyisilinda ezenziwe ngengilazi ezihlonyiswe ngendlela yokuvala i-screw cap. These vials are designed to securely store and protect various substances, such as liquids or solid samples.
Ukuvalwa kwekepisi lesikulufu salezi zitsha siqukethe ikepisi elinentambo elingasonteka kalula livule futhi livale ibhodlela. Le ndlela yokuvala iqinisekisa ukuvala okuqinile, ukuvimbela ukuvuza noma ukungcoliswa kokuqukethwe. I-screw cap ngokuvamile inomugqa noma i-septum ngaphakathi ukuze inikeze ukuvala nokuvikela okwengeziwe.
