Embodiment Construction

[0064] The accompanying drawing is the best embodiment of the high-precision control titration device, and the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0065] attached by figure 1 As shown, a high-precision control titration device includes a base 1 , a support column 2 , a glass burette 3 , a titration speed control device 5 , and a hanging liquid removal device 6 . The upper end surface of the base 1 is concaved with a shaking chamber 1a, and the shape of the shaking chamber 1a is circular.

[0066] The support column 2 is vertically fixed on the edge of the base 1, the glass burette 3 is vertically arranged above the shaking chamber 1a, and an upper end fixing sleeve rod 4a is arranged between the support column 2 and the glass burette 3. The left side of the fixed sleeve rod 4a at the upper end is fixedly connected with the glass burette 3, and the right side is sleeved on the support column 2 and can mov...

Abstract

The invention relates to a high-precision regulating titration device, comprising a base, a supporting column, a glass burette, a titration speed regulating device, a hanging liquid removing device, and an eccentric turntable. The supporting column is supported on the base; the glass burette is arranged beside the supporting column; the hanging liquid removing device is arranged at the tail end ofthe glass burette; and the titration speed regulating device is arranged outside the piston of the glass burette. The high-precision regulating titration device is reasonable in design and convenientto operate, accurate regulation of titration speed can be achieved by adjusting the speed regulating gear set, and meanwhile the beaker can be automatically shaken.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and in particular relates to a high-precision control titration device. Background technique [0002] The capacity of the burette is generally 50mL, and each large division of the scale is 1mL, and each large division is divided into 10 small divisions, so each small division is 0.1mL. The accuracy is one percent. It can be accurate to 0.01ml. A burette is an elongated tubular container with a stopcock at one end and a scale indicating the measurement. Generally, the reading on the upper scale is smaller, and the reading on the bottom is larger. It is an indispensable experimental equipment in the process of chemical experiments. [0003] On April 10, 2017, the Chinese patent published an adjustable speed sulfuric acid titrator with the application number 201720368053.8, including a titrator base, a circular automatic rotator is fixedly installed on the titrator base, and the c...
