Lab Sieve

What is a lab sieve

Lab Sieve is an experimental instrument used for screening and particle size analysis of granular materials. It usually consists of a series of sieves with different apertures, which are stacked in order of aperture size. Through sieves with different apertures, particles of different sizes can be separated to obtain information on particle size distribution. This is of great significance for research and production in the fields of materials science, chemistry, food, and medicine.

What are the uses of lab sieves?

1. Particle size analysis: It is one of the most important uses of lab sieves. In materials science research, the particle size distribution of metal powders, ceramic powders, etc. is determined by screening, so as to study the relationship between the physical and chemical properties of materials and particle size. For example, when studying the properties of nanomaterials, a lab sieve is needed to accurately analyze the particle size range of nanoparticles.

2. Quality control: In laboratories in the chemical, pharmaceutical, food and other industries, it is used to perform quality inspections on raw materials and products. In the pharmaceutical process, drug powders are screened to ensure that their particle size meets the requirements of the preparation and to ensure the quality and efficacy of the drug. In the food industry, it is used to detect the particle size of food raw materials (such as flour, powdered sugar, etc.) to ensure the taste and quality of the product.

3. Sample preparation: Provide samples with uniform particle size for subsequent experiments. In soil science research, Lab sieves are used to sieve soil samples to remove larger particles and impurities to obtain fine particle samples suitable for analyzing soil microorganisms, nutrient content, etc.

How does lab sieve work?

The sample to be tested is spread evenly on the sieve, and the particles are moved on the sieve by means of vibration or sieving machine. Particles of different particle sizes will pass through sieves of different apertures and eventually be sieved into particles of different grades.

The structure of lab sieve

Sieve frame: usually made of stainless steel, durable and not easy to deform.

Sieve mesh: woven from metal wires of different mesh sizes, the larger the mesh size, the smaller the aperture.

Chassis and cover: used to fix the screen to prevent material splashing during screening.

Classification of Lab sieves

1. Classification by screen shape

Circular Lab sieve: The sieve frame and screen are circular. The structure of this shape of Lab sieve is relatively symmetrical. The force of the material is uniform during the screening process, which is conducive to fine screening. When analyzing samples with high particle size requirements, circular Lab sieves can provide more accurate results.

Square Lab sieve: The sieve frame and screen are square, and its advantage is that the screening area is relatively large and can handle more materials. It has advantages when performing preliminary screening of larger batches of samples or screening materials with a wide particle size distribution. For example, in the preliminary screening of soil samples, square Lab sieves can more efficiently remove large particle impurities.

2. Classification by mesh material

Lab sieves of different materials: such as stainless steel wire woven mesh Lab sieve, perforated plate Lab sieve, plastic mesh Lab sieve, etc. Stainless steel wire woven mesh Lab sieve is suitable for fine screening of most materials; perforated plate Lab sieve is used for heavier and larger particles; plastic mesh Lab sieve has unique advantages in screening some materials with special chemical properties.

Advantages of Lab sieves

1. Accurate particle size analysis: It can accurately determine the content of particles of different particle sizes in the sample. Through screening, the particle size distribution curve of the sample is obtained, which intuitively reflects the particle size characteristics of the sample.

2. Efficient classification: It can quickly separate particles of different particle sizes to improve work efficiency. The purity of each level of particles after separation is high, which is conducive to subsequent experiments.

3. Strong customizability: Lab sieves are available in a variety of specifications to meet different experimental needs. Screens with different apertures can be customized according to experimental needs.

4. Simple operation: No special training is required. Some lab sieves have automation functions to improve work efficiency.
