低溫恒溫槽的使用及維護
低(di)溫恒溫槽需(xu)要(yao)定(ding)期清潔(jie)儀器,及時(shi)(shi)保(bao)持(chi)臺面板的清潔(jie);及時(shi)(shi)觀察油箱中(zhong)的液位。液位過低(di)時(shi)(shi),及時(shi)(shi)添(tian)加液體介質;考慮(lv)到(dao)安全系數,我們規定(ding)恒溫槽在(zai)100℃以上時(shi)(shi)應作內循環(huan)℃. 如(ru)按客戶要(yao)求(qiu)改為外(wai)循環(huan),客戶應特別注意出(chu)口管連接牢固(gu),嚴防脫落,以免燙(tang)傷(shang)。
低(di)溫恒溫槽使用注意(yi)事項(xiang):
1.在使(shi)用低(di)(di)溫(wen)(wen)恒(heng)溫(wen)(wen)槽前,向(xiang)槽中加入液(ye)體介(jie)(jie)質(zhi)。介(jie)(jie)質(zhi)液(ye)位應低(di)(di)于工作(zuo)臺(tai)約30mm,否則通電時(shi)會損(sun)壞加熱器;2.低(di)(di)溫(wen)(wen)恒(heng)溫(wen)(wen)槽中液(ye)體介(jie)(jie)質(zhi)的選擇應遵循以下原則:
工作(zuo)溫度5~85℃時℃, 液體(ti)介質(zhi)為水;
工(gong)作溫度85-95時℃, 液(ye)體介質可為(wei)15%甘油(you)水(shui)溶液(ye);當(dang)工(gong)作溫度高于95℃, 液(ye)體介質為(wei)油(you),所選油(you)的開(kai)杯閃點應(ying)大于50℃; 3.低溫節溫器(qi)制冷開(kai)關(guan)關(guan)閉后,再次(ci)打開(kai)制冷開(kai)關(guan)的間(jian)隔時間(jian)應(ying)為(wei)10~20分鐘(視環境溫度而(er)定)。
4.電(dian)(dian)源:220V AC 50Hz,電(dian)(dian)源應(ying)(ying)(ying)(ying)大于(yu)儀(yi)器(qi)總功率,且電(dian)(dian)源必須(xu)有(you)(you)良(liang)好的“接地(di)”裝置(zhi);5.儀(yi)器(qi)應(ying)(ying)(ying)(ying)放置(zhi)在干(gan)(gan)燥(zao)通(tong)風處(chu),儀(yi)器(qi)周(zhou)圍300mm范(fan)圍內(nei)不(bu)得有(you)(you)障礙物;6.培養箱工(gong)作(zuo)溫(wen)度高(gao)時,不(bu)應(ying)(ying)(ying)(ying)打開(kai)上蓋,手不(bu)應(ying)(ying)(ying)(ying)進(jin)入(ru)培養箱,以防燙(tang)傷;7.低溫(wen)恒(heng)(heng)溫(wen)槽應(ying)(ying)(ying)(ying)置(zhi)于(yu)干(gan)(gan)燥(zao)通(tong)風處(chu),儀(yi)器(qi)周(zhou)圍300mm范(fan)圍內(nei)不(bu)得有(you)(you)障礙物。低溫(wen)恒(heng)(heng)溫(wen)浴(yu)工(gong)作(zuo)溫(wen)度較低時,手不(bu)要進(jin)入(ru)浴(yu)內(nei),以防凍傷。使用完(wan)畢,關(guan)閉所有(you)(you)開(kai)關(guan),切斷電(dian)(dian)源。低溫(wen)恒(heng)(heng)溫(wen)槽應(ying)(ying)(ying)(ying)定期清(qing)洗(xi),保持(chi)工(gong)作(zuo)臺和操(cao)作(zuo)面板的清(qing)潔。
8.使(shi)用完畢,關(guan)閉(bi)所有開關(guan),切斷電源(yuan);
