Lab Sieve

What is a Lab Sieve?

Lab sieve is a device used to separate and classify particles of different sizes by passing them through a mesh or perforated surface, usually used in laboratories for particle size analysis and quality control testing of materials, sieves are usually made of fixed mesh or sieve Composed of a frame and a disc that collects material passing through the sieve, the mesh or sieve is selected according to the size range of the particles to be measured, ranging from 125mm to 20μm.

Lab sieve diameters include 75mm, 100mm, 200mm, 300mm, 400mm, and are usually made of high-quality materials such as stainless steel or brass to ensure durability and long-lasting performance. They are available in a variety of sizes and meshes, depending on the specific application and size range of the particles being measured.

What is the function of lab sieve?

Lab sieve is a piece of equipment used in scientific laboratories for particle size analysis and quality control purposes. A laboratory sieve is designed to separate particles according to their size by passing the material through a mesh or sieve with a specific opening.

1. Particle size analysis: they are used to determine the particle size distribution of materials (e.g. powders, granules and aggregates).

2. Quality control: They are essential for quality control processes in industries such as pharmaceutical, food, construction and mining to ensure that materials meet specified particle size requirements.

3、Research and Development: Lab sieve is used in R&D laboratories for product development, formulation and optimization, where knowledge of particle size distribution is critical.

4、Environmental analysis: In environmental laboratories, lab sieve is used to analyze soil samples, sediments and other environmental materials to understand their composition and properties.

What is a lab sieve used for?

Soil Science: Analyzing soil texture and particle size distribution.

Mining and Metallurgy: Grading minerals and ores based on particle size.

Pharmaceutical Industry: Ensuring the consistency and quality of powders and granules.

Food Industry: Evaluating the texture and particle size of food products.

Chemical Engineering: Separating different components of mixtures based on particle size.

Types of lab sieve

Lab sieves are categorized based on their mesh material, construction, and intended use. Here are some common types:

Based on Mesh Material:

Wire Mesh Sieves: The most common type, constructed with woven wire mesh. They offer excellent particle separation and are suitable for a wide range of applications.

Perforated Plate Sieves: Feature perforated plates with holes of specific sizes. They are typically used for larger particles and offer durability in harsh environments.

Electroformed Sieves: Made by electroplating metal onto a substrate to create a precise mesh pattern. They are highly accurate and ideal for fine particle analysis.

Based on Construction:

Single-Sieve: A single sieve with a specific mesh size.

Lab Sieve Set: A stack of sieves with decreasing mesh sizes, used for analyzing a sample over a wide range of particle sizes.

How does lab sieve work?

Working principle of lab sieve is to place mixed particles or powder samples on the sieve through the pore size of the sieve, and then mechanically vibrate or manually shake the sieve, so that the particles are separated through the sieve holes according to size, and the smaller particles pass through the sieve. The larger particles are blocked on the screen to achieve separation and screening of particles, thereby achieving the purpose of classifying particles of different sizes.
