滴定管尖嘴处套接移液枪枪头的应用

Application of Buret Beak Socket Connection with Pipette Tip

在常量滴定管尖嘴处套接移液枪枪头,不仅可以更加精细的控制滴定管排出液滴的体积,而且可以有效控制排出液滴体积的恒定性,大幅度降低因滴定管中液体液面下降而导致的排出的液滴体积的标准偏差,有效提高滴定精度,减小实验误差。这种方法方便快捷、成本低、稳定性好、易操作,尤其适用化工企业中的常量和半微量滴定,且不受滴定管规格的限制。

The constant buret beak socket connects with pipette tip, which not only can more carefully control the volume of the droplet, but also can effectively control the constancy of the drop- let volume. It can effectively reduce the standard deviation due to the liquid level drops of burette, improve the accuracy of titration and reduce the experiment error. The application of this method is convenient and quick ,the cost is low and the stability is well ,the operation is easy. It is especially suitable to the constant titration and half of microtiter in chemical factory, which is not restricted by burette specifications.
