Tsarin Shiri na Oxalic Acid Daidaitacce
Tsarin shirya maganin dole ne ya bi ƙa'idodin kimiyyar sinadarai na dakin gwaje-gwaje. Da farko, zaɓi kwantena da aka yi da polyethylene mai yawan yawa (HDPE), wanda ke ba da juriya ga oxalic acid idan aka kwatanta da robobi na yau da kullun. Ana iya amfani da kwantena na gilashi na ɗan lokaci, amma ajiya na dogon lokaci na iya haifar da fitar da sodium ion, wanda ke shafar daidaiton maganin.

Oxalic Acid – Zibo Anhao Chemical Co., Ltd.
Kamfanin Zibo Anhao Chemical Co., Ltd. amintaccen mai kera kuma mai samar da sinadarin oxalic acid mai tsarki (ethanedioic acid, CAS 144‑62‑7) wanda hedikwatansa ke Zibo, Shandong, China. Ana samun sinadarin oxalic acid ɗinmu a cikin nau'ikan da ba su da ruwa (C₂H₂O₄, MW 90.03) da kuma nau'ikan dihydrate (H₂C₂O₄·2H₂O, MW 126.07), wanda ke da mafi ƙarancin tsarkin kashi 99.6%. Yana bayyana a matsayin lu'ulu'u masu haske marasa launi ko farin foda mai lu'ulu'u, ba shi da ƙamshi, kuma yana narkewa sosai a cikin ruwa da ethanol.
