一、玻璃器皿可以放微波爐加熱
玻璃器皿常被用來盛裝食物,有時需要加熱食物,很多人直接將玻璃器皿放入微波爐,實際上這是比較危險的,因為普通玻璃器皿不能用于加熱烹飪使用環境,它的耐熱能力較差,通常只能承受60℃左右的溫度,急速加熱可能導致玻璃炸裂;未經處理的鋼化玻璃器皿放入微波爐有自爆傷人風險,還可能析出金屬成分危害人體健康;只有正規玻璃器皿品牌廠家生產(chan)的,以硼硅酸玻(bo)璃、微(wei)(wei)(wei)晶(jing)玻(bo)璃、氧化鈦(tai)結(jie)晶(jing)玻(bo)璃為(wei)原(yuan)料的耐熱玻(bo)璃器(qi)皿(min)和微(wei)(wei)(wei)波加(jia)熱專用玻(bo)璃器(qi)皿(min)可以放微(wei)(wei)(wei)波爐加(jia)熱。
二、玻璃器皿有哪些分類
玻(bo)(bo)(bo)璃(li)器(qi)(qi)皿(min)就(jiu)是(shi)用(yong)玻(bo)(bo)(bo)璃(li)所造的器(qi)(qi)皿(min),它的種(zhong)類(lei)眾多,按(an)用(yong)途(tu)可(ke)分(fen)(fen)為玻(bo)(bo)(bo)璃(li)酒具、玻(bo)(bo)(bo)璃(li)水杯、玻(bo)(bo)(bo)璃(li)餐具等(deng)日用(yong)玻(bo)(bo)(bo)璃(li)器(qi)(qi)皿(min)以及燒杯、儲存(cun)瓶等(deng)實驗(yan)室用(yong)化學玻(bo)(bo)(bo)璃(li)器(qi)(qi)皿(min);按(an)成(cheng)分(fen)(fen)可(ke)分(fen)(fen)為鈉鈣玻(bo)(bo)(bo)璃(li)器(qi)(qi)皿(min)、水晶玻(bo)(bo)(bo)璃(li)器(qi)(qi)皿(min)、微晶玻(bo)(bo)(bo)璃(li)器(qi)(qi)皿(min)、耐熱玻(bo)(bo)(bo)璃(li)器(qi)(qi)皿(min)、有(you)色玻(bo)(bo)(bo)璃(li)器(qi)(qi)皿(min)等(deng);按(an)成(cheng)型(xing)(xing)方(fang)法分(fen)(fen)可(ke)分(fen)(fen)為吹制成(cheng)型(xing)(xing)、壓制成(cheng)型(xing)(xing)、離心成(cheng)型(xing)(xing)、自由成(cheng)型(xing)(xing)等(deng)。
三、玻璃器皿的洗滌方法
玻(bo)(bo)璃(li)器(qi)(qi)(qi)皿需(xu)(xu)(xu)要(yao)(yao)定期清(qing)(qing)洗(xi)(xi)(xi)(xi),尤其(qi)是實(shi)(shi)(shi)驗(yan)(yan)室(shi)用(yong)的(de)玻(bo)(bo)璃(li)器(qi)(qi)(qi)皿,如果不清(qing)(qing)洗(xi)(xi)(xi)(xi)干凈,會影響實(shi)(shi)(shi)驗(yan)(yan)的(de)效果。新買的(de)玻(bo)(bo)璃(li)器(qi)(qi)(qi)皿需(xu)(xu)(xu)要(yao)(yao)浸泡(pao)鹽酸溶液除去游離的(de)堿性物質,再用(yong)清(qing)(qing)水沖洗(xi)(xi)(xi)(xi);舊的(de)玻(bo)(bo)璃(li)器(qi)(qi)(qi)皿清(qing)(qing)水沖洗(xi)(xi)(xi)(xi)即(ji)可,如果需(xu)(xu)(xu)要(yao)(yao)滅菌(jun)則需(xu)(xu)(xu)要(yao)(yao)進(jin)行(xing)高溫滅菌(jun)處理。實(shi)(shi)(shi)驗(yan)(yan)室(shi)玻(bo)(bo)璃(li)器(qi)(qi)(qi)皿清(qing)(qing)洗(xi)(xi)(xi)(xi)一(yi)般(ban)有(you)人工(gong)清(qing)(qing)洗(xi)(xi)(xi)(xi)、超聲(sheng)波清(qing)(qing)洗(xi)(xi)(xi)(xi)和(he)實(shi)(shi)(shi)驗(yan)(yan)室(shi)洗(xi)(xi)(xi)(xi)瓶機清(qing)(qing)洗(xi)(xi)(xi)(xi)三種方法,其(qi)中(zhong)實(shi)(shi)(shi)驗(yan)(yan)室(shi)洗(xi)(xi)(xi)(xi)瓶機清(qing)(qing)洗(xi)(xi)(xi)(xi)最實(shi)(shi)(shi)用(yong),但成本相(xiang)對(dui)更高。
四、玻璃器皿滅菌方法
實驗(yan)室用的玻璃器(qi)皿在進(jin)行實驗(yan)之前通常要進(jin)行滅(mie)(mie)菌(jun)(jun)(jun)處理(li)玻璃器(qi)皿的滅(mie)(mie)菌(jun)(jun)(jun)流程(cheng)分(fen)為清(qing)洗、包扎、滅(mie)(mie)菌(jun)(jun)(jun)三個(ge)步(bu)驟,一般(ban)采(cai)用物(wu)理(li)方法滅(mie)(mie)菌(jun)(jun)(jun),包括(kuo)干(gan)熱滅(mie)(mie)菌(jun)(jun)(jun)法和濕熱滅(mie)(mie)菌(jun)(jun)(jun)法兩種:干(gan)熱滅(mie)(mie)菌(jun)(jun)(jun)主(zhu)要是利用恒溫干(gan)燥箱和酒精燈火焰燒(shao)灼(zhuo)滅(mie)(mie)菌(jun)(jun)(jun);濕熱滅(mie)(mie)菌(jun)(jun)(jun)法包括(kuo)高(gao)壓蒸(zheng)(zheng)汽(qi)滅(mie)(mie)菌(jun)(jun)(jun)法、煮沸(fei)滅(mie)(mie)菌(jun)(jun)(jun)法、巴(ba)氏消毒法、流通蒸(zheng)(zheng)汽(qi)滅(mie)(mie)菌(jun)(jun)(jun)法及(ji)間(jian)歇蒸(zheng)(zheng)汽(qi)滅(mie)(mie)菌(jun)(jun)(jun)法。
