保存：RT，避光溴化鋅號：7699-45-8儲存條件：
避光、干燥陰涼處封閉貯存,嚴禁與有毒、有害物品混放、混運。本品為非危險 產(chǎn)品可按一般化學品運輸,輕搬動輕放,防止日曬、雨淋！受熱、受潮、受光后易喪失活力,保存期短,因此貯存和運輸條件比較苛刻。
運輸：汽車運輸、EMS郵政快遞，申通快遞等， 款到上海3天內(nèi)發(fā)貨； 
售后：如您對我們的產(chǎn)品服務(wù)及技術(shù)指標有特殊要求，請及時通知我方。 
存儲：應(yīng)貯存在干燥清潔避光的環(huán)境中，嚴禁與有毒物質(zhì)混放，以免污染（保質(zhì)期為兩年）。 
主要優(yōu)級純、分級純和化學純3種：
（1）優(yōu)級純（GR：Guaranteed reagent），又稱一級品或保證試劑，99.8%，這種試劑純度Z高，雜質(zhì)含量Z低，適合于重要精密的分析工作和科學研究工作，使用綠色瓶簽。
（2）分析純（AR），又稱二級試劑，純度很高，99.7%，略次于優(yōu)級純，適合于重要分析及一般研究工作，使用紅色瓶簽。
（3）化學純（CP），又稱三級試劑，≥ 99.5%，純度與分析純相差較大，適用于工礦、學校一般分析工作。使用藍色（深藍色）標簽。
（4）實驗試劑（LR：Laboratory reagent），又稱四級試劑。
