真空離心濃縮儀的維護(hù)工作有幾步

更新時(shí)間:2023-01-16點(diǎn)擊次數(shù):1816
  真空離心濃縮儀,綜合利用了離心、抽真空和加熱等手段,有效地蒸發(fā)溶劑,高效率回收生物或分析樣品。廣泛地應(yīng)用到生命科學(xué)和化學(xué)、制藥等領(lǐng)域。它具有批次處理樣品量大、幾乎不受容器限制、低溫保證樣品活性、蒸發(fā)速度快、不污染環(huán)境等眾多優(yōu)點(diǎn),逐漸被廣大科研、生產(chǎn)、檢測(cè)單位所熟悉。
  而在日常的使用過程中,使用者也應(yīng)該注意以下離心濃縮儀的日常維護(hù)工作,為儀器的正常運(yùn)行保駕護(hù)航。
  1、加熱介質(zhì):使用蒸餾水和去離子水,這將防止在水浴壁上產(chǎn)生水垢。注意不要使用有機(jī)溶劑作加熱介質(zhì)。
  2、除藻劑:不加熱時(shí),在水浴的水中加以除藻劑,可防止生物污染。不應(yīng)使用酸性除藻劑,并應(yīng)確保所用除藻劑不會(huì)影響所要處理的樣品。
  3、換水:水浴中的水建議一周一換,最長(zhǎng)不超過一月。
  4、酸性環(huán)境:當(dāng)接觸或暴露于酸性材料、蒸汽或樣品后,應(yīng)當(dāng)立刻清洗,用適度的碳酸氫鈉溶液或其它相似溶液中和,再用清水沖洗。長(zhǎng)時(shí)間接觸酸性物質(zhì),將會(huì)損壞儀器。如必須長(zhǎng)時(shí)間接觸酸性物質(zhì),則應(yīng)采取保護(hù)措施。
  5、針頭:每次使用完針后都應(yīng)清洗,盡量減少針的污染??墒褂糜袡C(jī)溶劑沖洗、高壓消毒和索氏提取等技術(shù)。
  6、浸沒:浴底耐水但不防水。絕不能將水浴浸泡在任何液體中,或放置在可能發(fā)生浸泡的地方。
