PCR仪的维护与保养  发帖心情 Post By:2008/8/5 11:24:56

    虽然PCR仪器不是一种计量仪器,但其主要作用原理与基本计量要素密切相关,要求较高,一旦失控,仪器将不能正常工作,所以PCR仪器也需要定期检测和维护,这对依赖自然风降温的PCR仪器尤为重要。在仪器的维护保养中,需要注意以下问题:
 
    1)PCR仪器需要定期检测,视制冷方式而定一般半年至少一次。
 
    2)PCR反应的要求温度与实际分布的反应温度是不一致的,当检测发现各孔平均温度差偏离设置温度大于1—2‘C时,可以运用温度修正法纠正PCR实际反应温度差。
 
    3)PCR反应过程的关键是升、降温过程的时间控制,要求越短越好,当PCR仪的降温过程超过60s,就应该检查仪器的制冷系统,对风冷制冷的PCR仪要较彻底地清理反应底座的灰尘;对其他制冷系统应检查相关的制冷部件。
 
    4)一般情况如能采用温度修正法纠正仪器的温度时,不要轻易打开或调整仪器的电子控制部件,必要时要请专业人员修理或利用仪器电子线路详细图纸进行维修。
 
    下面介绍一些具体的保养维护方法。
 
1.样品池的清洗
    先打开盖子,然后用95%乙醇或10%清洗液浸泡样品池5min,然后清洗被污染的孔;用微量移液器吸取液体,用棉签吸干剩余液体;打开PCR仪,设定保持温度为50~C的PCR程序并使之运行,让残余液体挥发去除。一般5~10min即可。
 
2.热盖的清洗
    对于荧光定量PCR仪,当有荧光污染出现,而且这一污染并非来自样品池时;或当有污染或残迹物影响到热盖的松紧时,需要用压缩空气或纯水清洗垫盖底面,确保样品池的孔镜干净,无污物阻挡光路。
 
3.仪器外表面的清洗
    清洗仪器的外表面可以除去灰尘和油脂,但达不到消毒的效果。选择没有腐蚀性的清洗剂对PCR仪的外表面进行清洗。
 
4.更换保险丝
    先将PCR仪关机,拔去插头,打开电源插口旁边的保险盒,换上备用的保险丝,观察是否恢复正常。
