Due to its unique physical and chemical properties, quartz tubes are widely used in the field of measuring instruments. Quartz tubes have the advantages of high purity, high transparency, low coefficient of expansion, high temperature resistance, corrosion resistance, etc. These characteristics make them an ideal material for many precision measuring equipment. So what are the main applications of quartz tubes in measuring instruments?

1. Optical rotation standard quartz tube

Optical standard quartz tube is a measuring standard instrument used for calibrating polarimeters and polarimeters. It is made of quartz crystal and has the characteristics of small temperature coefficient, stable performance, high processing accuracy, small size and convenient use. Its technical specifications comply with the recommendations of the International Legal Metrology Organization and are widely used in sugar, pharmaceutical, medical, chemical, beverage and other industries.

Purpose: It is used to calibrate the indications of various polarimeters and sugar meters to ensure the long-term stability of the instrument and the accuracy of the measurement results.

- Technical parameters:

- Dimensions: 120mm x 30mm.

The nominal value of optical rotation and sugar content has various specifications, such as ± 5 °, ± 17 °, ± 34 °, etc.

The difference between the standard value and the nominal value shall not exceed ± 1 °, and the directional error shall not exceed ± 0.003 °.

2. High-precision quartz tube automatic detection system

High-precision quartz tube detection is essential for the production and calibration of measuring instruments. The quartz tube automatic detection system uses photoelectric encoder and laser measurement sensor to detect the bubble, gas line, diameter and wall thickness of the quartz tube.

- Detection content:

- Detect the bubbles and gas lines of the quartz tube.

Measure the diameter and wall thickness of quartz tubes with an accuracy of up to 5mm.

System components:

- Includes Photoelectric Encoder, Laser Measurement Sensor and Control Unit.

The Control Unit is capable of processing and storing measurement data and displaying the results to the user via an electronic graphic display.

3. Laboratory measuring instruments

Quartz tubes are also commonly used in laboratories to make measuring instruments such as chemical reactors, pipes, and gauges. These instruments need to have high temperature resistance, corrosion resistance, and high transparency to ensure the accuracy and safety of experiments.

- application field: chemical industry, laboratory instruments.

- Characteristics: acid resistance, alkali resistance, high temperature resistance, corrosion resistance.

4. Applications in other measuring instruments

Quartz tubes can also be used to make other measuring instruments, such as liquid level gauges and sight glasses. These instruments take advantage of the high transparency and corrosion resistance of quartz tubes to accurately measure the level of liquids in industrial environments.

- application fields: industrial processes, vacuum systems.

Characteristics: high transparency, high temperature resistance, corrosion resistance.

Quartz tubes are widely used and important in measuring instruments. Their characteristics such as high purity, high transparency, low coefficient of expansion and corrosion resistance make them an ideal material for many precision metrology devices. Whether it is a polarizing standard quartz tube used to calibrate polarimeters, or a measuring instrument used in laboratory and industrial environments, quartz tubes provide measurement support with high precision, high stability and high reliability.

Luverre Quartz can manufacture customized quartz tubes in various shapes, such as spiral, square, round, with processing including cutting, bending, welding, etc., and available in different colors, such as transparent quartz tubes, opaque quartz tubes, milky white quartz tubes, red quartz tubes, and so on.
