1. Overview of glass capillary tubes
A glass capillary tube is a slender, hollow, tiny glass tube. Glass capillary tubes have a characteristic called the capillary effect, that is, in a tiny tube, the surface tension of a liquid or gas will cause it to form a curved surface inside. Glass capillaries can accurately measure physical quantities such as surface tension, viscosity and density of liquids and gases.
2. Application scope of glass capillary tube
1. Chemical industry
Glass capillaries are widely used in the chemical industry, mainly for measuring the interaction between chemical and biological molecules, such as surface tension, viscosity, surfactant concentration, etc.
In the pharmaceutical field, glass capillaries can be used to purify and identify the chemical and physical properties of different compounds, such as viscosity, surface tension, wettability, and flexibility.
3. Laboratory field
In the laboratory field, glass capillary tubes are used for laboratory and scientific research. For example, glass capillaries can be used in chemical experiments to control the rate of dosing of liquid reagents and to measure the viscosity of samples.
3. Characteristics of glass capillary tubes
1. High precision
The very fine dimensions of glass capillaries enable extremely high measurement accuracy.
2.Easy to operate
The operation of the glass capillary tube is relatively simple, and the measurement work can be completed through simple experiments.
3. Small volume
The volume of glass capillary tubes is very small, which can avoid wasting materials and increasing experimental costs in the laboratory.
4.Long service life
Glass capillary tubes are made of high quality glass and have a long service life.
In short, glass capillary tubes have a wide range of applications and play an important role in chemical industry, pharmaceuticals and laboratories. Its characteristics of high precision, easy operation, small volume, and long service life make it an important tool for measuring and controlling physical quantities of liquids and gases.
