冷(leng)凍幹燥機凍幹制品(pin)時(shi)升華時(shi)溫(wen)度(du)限(xian)制(zhi)

冷凍幹燥機凍幹制品(pin)時(shi)，升華時(shi)受到(dao)溫(wen)度(du)限(xian)制(zhi)，冷(leng)凍幹燥機擱(ge)板(ban)的溫(wen)度(du)應根(gen)據制(zhi)品(pin)的溫(wen)度(du)、凍幹箱真空度(du)、冷凝器的溫(wen)度(du)來確定。為(wei)了(le)提高壹階(jie)段(duan)的升華(hua)速度(du)，可將(jiang)擱(ge)板(ban)溫(wen)度(du)壹次升高至制品允(yun)許的上限(xian)溫(wen)度(du)以(yi)上；待(dai)大(da)量升華(hua)階(jie)段(duan)基本(ben)結(jie)束(shu)時(shi)，再將(jiang)板溫(wen)降至允(yun)許的上限(xian)溫(wen)度(du)，但是為(wei)了(le)避免擱(ge)板(ban)溫(wen)度(du)過高而(er)產生變(bian)性或燒壞，擱(ge)板(ban)溫(wen)度(du)應限(xian)制(zhi)在某(mou)壹安全(quan)值(zhi)以(yi)下。制品(pin)升(sheng)華時受(shou)下列幾(ji)種(zhong)溫(wen)度(du)限(xian)制(zhi)：（1）制(zhi)品的凍結(jie)部(bu)分(fen)的溫(wen)度(du)應低(di)於產品共(gong)溶(rong)點(dian)溫(wen)度(du)；（2）產品幹燥部(bu)分(fen)的溫(wen)度(du)必須低(di)於其(qi)崩解溫(wen)度(du)或容(rong)許的上限(xian)溫(wen)度(du)；（3）上限(xian)擱(ge)板(ban)溫(wen)度(du)。冷凍幹燥機Pilot5-8E應用(yong)於凍幹活性物(wu)質原(yuan)料更便捷。全(quan)自動(dong)系統，壹鍵啟(qi)動(dong)，遠(yuan)程(cheng)控制(zhi)系統手(shou)機監測(ce)系統全(quan)程(cheng)監控(kong)無需人員值(zhi)守。捕水(shui)能(neng)力(li)強(qiang)，適合各(ge)種(zhong)蛋白核(he)酸多(duo)糖(tang)原(yuan)料凍幹，適合聚合物(wu)納米(mi)材(cai)料石墨烯水(shui)凝(ning)膠(jiao)材(cai)料凍幹。購(gou)買冷(leng)凍幹燥機含(han)凍幹工藝(yi)免(mian)費開(kai)發(fa)服務。
