Izitsha ze-EPA VOA zifaka indlela yokuvala evikelekile ukuze kugcinwe ubuqotho besampula nokuvimbela ukuvuza kwesampula noma ukungcola. Amabhodlela ngokuvamile afika ne-screw cap efakwe i-septum, eqinisekisa uphawu oluqinile futhi olungavuzi. Le ndlela yokuvala iqinisekisa ukulondolozwa kwezinhlanganisela eziphilayo eziguquguqukayo ngesikhathi sokugcinwa nokuthutha.

I-20-60mL EPA VOA Storage Vial iyisitsha esikhethekile esiklanyelwe ukugcinwa nokugcinwa kwamasampula e-Volatile Organic Analysis (VOA) elabhorethri. Inebanga lomthamo we-20-60mL, inikeza isikhala esanele sokuqoqwa kwesampula nokugcinwa. Ibhodlela lenziwe ngezinto ezisezingeni eliphezulu, ezimelana namakhemikhali ukuze kuqinisekiswe ubuqotho besampula ngesikhathi sokugcina isikhathi eside.

Izitsha ze-EPA kufanele zihlanzeke futhi zingabi nezinto ezingase zibe nomthelela ekuhlaziyeni. Izitsha Zengilazi ezihlangabezana nalezi zidingo zibizwa ngokuthi izitsha ze-EPA, noma ngezinye izikhathi izitsha ze-VOA (volatile organic analysis). Izitsha ze-EPA eziphansi eziyisicaba ze-Aijiren zitholakala ngosayizi abangama-20, 30, 40 kanye no-60ml, afanele amanzi noma amasampula omhlabathi.

Izitsha ze-EPA yilezo ezihlangabezana nezimfuneko ze-US Environmental Protection Agency (EPA) ukuze kuhlolwe ukungcola okungaba yingozi kwemvelo emanzini noma kumasampula enhlabathi. Ukuze usetshenziselwe ukuhlaziya imvelo, izitsha ze-EPA kufanele zihlanzeke futhi zingabi nezinto ezingase zibe nomthelela ekuhlaziyeni.

Izitsha ze-EPA yilezo ezihlangabezana nezimfuneko ze-U.S. Environmental Protection Agency (EPA) zokuhlola ukungcola okungaba yingozi kwemvelo emanzini noma kumasampula omhlabathi.

Izitsha Eziyisampula Zesitoreji ezikhiqizwe i-Aijiren zinamandla amaningi ahlukene. Ukuze uvumelane namakhasimende ahlukene, banokuvuleka okungu-24mm kanye nemicu evamile engu-24-400. Isampula yokugcina vial ingabuye ibizwe ngokuthi i-EPA Vials. Ikhithi yesampula yesampula evunguzayo ye-Aijiren EPA inikeza i-cap yomhlangano kanye nesevisi ye-Septa ukuze wonge isikhathi kunqubo yokulungiselela isampula. I-Aijiren inamandla ahlukahlukene kanye nokucaciswa kwe-20ml-60ml ongakhetha kukho, engahlangabezana nezidingo ezahlukahlukene zamakhasimende zamasampula.

Izitsha zokugcina ezinezintambo zinokuzinza okuhle kakhulu kwamakhemikhali, ezingenambala nezinsundu ziyatholakala, futhi zinokuvaleka okuhle kakhulu nokumelana nokugqwala. Lolu chungechunge lwemikhiqizo lwakhiwe futhi lwakhiqizwa ngokuhambisana nezidingo ze-US EPA, ezinezindawo ezinhle zokugcina. I-septum nekepisi lepulasitiki kuhlanganiswe ndawonye ukuze kugwenywe ukuhwamuka ngokweqile futhi kugcinwe ibhodlela lesampula livalwe kahle.

Izigqoko ze-vial zochungechunge lwesitoreji zenziwe ngekhwalithi eyinhloko ye-polypropylene, ehlanganisa emisha nokulula okonga isikhathi. Isivalo se-vial esingenakhemikhali esikhiqizwe yile ndlela sihlanganisa ngempela i-septum nesivalo sepulasitiki ezingeni lamangqamuzana, okungagwema ukuhwamuka ngokweqile futhi kugcine isampula lebhodlela livalwe kahle.
