① Small particle materials fall into the lower sieve frame through the sieve holes of the upper sieve
② Large particle materials are trapped in the upper sieve mesh
③ After a set period of vibration, each layer of sieve intercepts materials within the corresponding particle size range
④ Remove the sieve frame, weigh each layer of material separately, and calculate the particle size distribution ratio (such as the percentage of material weight in a certain sieve layer to the total weight)

Sample screening laboratory specific testing
- Commodity name： Sample screening laboratory specific testing
Product Introduction
Standard test screening machine - a laboratory tool for precise screening
The standard test screening machine generates high-frequency vibrations in the vertical or horizontal direction through a vibration source (some models use three-dimensional vibration, which is a combination of vertical, horizontal, and torsional motion). The material placed inside the screening frame is subjected to vibration:
- Product Features
High screening accuracy
Paired with standard test sieves (sieve size in accordance with international or domestic standards, such as 1S0, ASTM, GB/T, etc.), the mesh material is mostly stainless steel (304 or 316), and the aperture error is extremely small (such as within ± 3%), ensuring the accuracy of particle size analysis.
Standard Operations
Accurate control of vibration time, frequency and other parameters can be achieved to ensure consistent test conditions and reproducible results, meeting the laboratory's requirements for data reliability
Compact
Small in size (usually desktop design), occupying less laboratory space, suitable for screening small samples (several grams to several hundred grams)
Stable operation
Reasonable design of vibration source, uniform amplitude, avoiding local accumulation of materials on the screen, and improving screening efficiency; The shock absorption system reduces the vibration interference of equipment on the surrounding environment
High safety
Some models are equipped with protective covers to prevent material splashing; The specialized models for the food and pharmaceutical industries adopt a blind spot design, which is easy to clean and meets hygiene standards such as GMP

Product Details
Usage steps
1. Determine the standard screening tool to be selected based on the inspected material and corresponding standards.
2. Stack the standard screening tools on the tray seat in ascending order of aperture, from bottom to top, and position the standard screening with grooves or positioning screws.
3. Place the inspected material into the top standard sieve (or cover the top of the standard sieve), and then press the standard sieve with the sieve head fitted on the screw column. Tighten the nut on the screw column to tighten the standard sieve. (Note: Apply consistent force on both sides and lock them with locking screws.)
4. Place the timer switch in the appropriate position (note to read the timer instructions, different settings set different times), then turn on the power switch, and the inspection screen will start working.
5. After the standard inspection sieve stops working, unscrew the nut on the screw column, move the sieve head away, and carefully remove the standard sieve tool.
6. Cut off the power supply.
