Addgene Comments
Using FLEX vectors in vivo: LoxP sites in FLEX plasmids are known to recombine during DNA amplification and viral vector production, which may result in a minority of Cre-activated (i.e., "flipped") viral vectors. Addgene has measured this occurs in 0.01-0.03% of viral vectors in our typical production protocol. This can lead to a small number of cells exhibiting Cre-independent transgene expression in vivo. To address this, we recommend titrating to find the optimal AAV dosage required for Cre-dependent transgene expression and function in vivo. This may include reducing the viral vector dosage in order to reduce the likelihood of Cre-independent expression.

便携式pH计主要用于现场和野外测方式,要求较高的精度和完善的功能。
实验室pH计是一种台式高精度分析仪表,要求精度高、功能全,包括打印输出、数据处理等等。
工业pH计是用于工业流程的连续测量,不仅要有测量显示功能,还要有报警和控制功能,以及安 装、清洗、抗干扰等等问题的考虑。
2.据ph计仪器精度分类:可分为0.2级、0.1级、0.05级、0.01级,数字越小,精度越高。
3.根据元器件类型分类:可分为晶体管式、集成电路式和单片机微电脑式,现在更多的是应用微电脑芯片,大大减少了仪器体积和单机成本;但芯片的开发成本很贵。
4根据读数指示分类:可分为指针式和数字显示式二种。指针式pH计现在已很少使用,但指针式仪表能够显示数据的连续变化过程,因此在滴定分析中还有使用。
5.看PH计有没有附带功能,比方说带标配RS232接口,还有一个很重的是温度补偿是自动
还是手动,自动温度补偿的PH计要比手动温度补偿的PH计要方便些,二者之间的价格你就明白了吧。
斜率的计算是和电极测量你所配制的溶液的电位有关系的。
三个标准缓冲液,标定的时候一般选择两个就行,如果三个都参与标定,斜率会相应的有差别。
电极的话,分立的电极是参比和测量各一支,分别接在仪器后面,使用时一起测量。复合电极,有的是参比和测量复合电极,应该只有一个球泡。还有一种三复合电极,是参比,测量,还有温度都集于一支电极上,上面除了玻璃球泡,那个小黑的是测量溶液温度的。
进口品牌JENCO的性价比比较高。
按测量精度
可分0.2级、0.1级、0.01级或更高精度。
按仪器体积
分为笔式(迷你型)、便携式、台式还有在线连续监控测量的在线式。
根据使用的要求
笔式(迷你型)与便携式pH酸碱度计一般是检测人员带到现场检测使用。
选择pH酸碱度计的精度级别是根据用户测量所需的精度决定,而后根据用户方便使用而选择各式形状的pH计。
◆按便携性分的,分为:便携式pH计,台式pH计和笔式pH计。
◆按用途分为:实验室用pH计,工业在线pH计等。
◆按先进程度分为经济型pH计,智能型pH计,精密型pH计或分为指针式pH计,数显式pH计。
◆笔式pH计,一般制成单一量程,测量范围狭,为专用简便仪器。
便携式和台式pH计测量范围较广,常用仪器,不同点是便携式采用直流供电,可携带到现场。实验室pH计测量范围广、功能多、测量精度高。
工业用pH计的特点是要求稳定性好、工作可靠,有一定的测量精度、环境适应能力强、抗干扰能力强,具有模拟里量输出、数字通讯、上下限报警和控制功能等。向左转|向右转
玻璃电极在初次使用前,必须在蒸馏水中浸泡一昼夜以上。
平时也应浸泡在蒸馏水中以备随时使用。玻璃电极不要与强吸水溶剂接触太久,在强碱溶液中使用应尽快操作,用毕立即用水洗净,玻璃电极球泡膜很薄,不能与玻璃杯及硬物相碰;玻璃膜沾上油污时,应先用酒精,再用四氯化碳或乙醚,最后用酒精浸泡,再用蒸馏水洗净。注意电极内要充满氯化钾溶液,应无气泡,防止断路。应有少许氯化钾结晶存在,以使溶液保持饱和状态,使用时拨去电极上顶端的橡皮塞,从毛细管中流出少量的氯化钾溶液,使测定结果可靠。
另外,pH测定的准确性取决于标准缓冲液的准确性。酸度计用的标准缓冲液,要求有较大的稳定性,较小的温度依赖性。
测定时把复合电极插在被测溶液中,由于被测溶液的酸度(氢离子浓度)不同而产生不同的电动势,将它通过直流放大器放大,最后由读数指示器(电压表)指出被测溶液的pH值。酸度计能在0~14pH值范围内使用。酸度计有台式、便携式、表型式等多种,读数指示器有数字式和指针式两种.
1、校正:先将仪器斜率调节器调节在100%位置,再根据被测溶液的温度,调节温度调节器到该温度值。
2、定位:把复合电极插入仪器,选择一种最接近样品pH值的缓冲溶液,把电极放入这一缓冲溶液里,摇动烧杯,使溶液均匀.待读数稳定后,该读数应是缓冲溶液的pH值,否则就要调节定位调节器。用于分析精度要求较高的测定时,要选择两种缓冲溶液(即被测样品的pH值在该两种缓冲溶液的pH值之间或接近)。待第种缓冲溶液的pH值读数稳定后,该读数应为该缓冲溶液的pH值,否则调节定位调节器。清洗电极,吸干电极球泡表面的余液。把电极放入第二种缓冲溶液中,摇动烧杯使溶液均匀,待读数稳定后,该读数应是第二种缓冲溶液的pH值,否则调节斜率调节器。
3、测量:经过pH标定的仪器,即可用来测定样品的pH值。这时温度调节器、定位调节器、斜率调节器都不能再动,用蒸馏水清洗电极,用滤纸吸干电极球部后。把电极插在盛有被测样品的烧杯内,轻轻摇动烧杯,待读数稳定后,就显示被测样品的pH值。复合电极的主要传感部分是电极的球泡,球泡极薄,千万不能跟硬物接触。测量完毕套上保护帽,帽内放少量补充液(3mol/L的氯化钾溶液),保持电极球泡湿润.仪器采用CMOS集成电路,不用时插入短路插头。检修时电烙铁要有良好的接地,以保护仪器。
