    Description

    新缓冲试剂带商标



    试剂
    精度:±0.01pH      pH值:4.00、6.86、9.18

    配置时极易造成配置误差,为确保配置精度要注意三个方面事项:

    1、粉剂要完全倒入,为避免配置误差,最好用水冲洗一遍塑料袋

    2、配置用水的电导率要控制在2us/cm以内,一般用蒸馏水或超纯水即可

    3、250ml是指25°C时的水体积

    配置时要注意器皿的清洁,要防止细菌进入溶液,以便延长保存时间,配置好的缓冲剂要保存在棕色密封瓶,保存期不宜超过五天。


     
    缓冲液的使用:250mL的缓冲液可以分多次使用,
    在仪器进行标定时用三个塑料(玻璃)小容器,
    分别倒入4.00、6.86和9.18缓冲液,并做好标记。
    缓冲   液使用量只要能够全部淹没玻璃电极即可。
    使用过的缓冲液应倒掉不要重复使用。剩余部分存放
    在20-25℃阴凉干燥处。
