Electromagnetic sieve shaker EMS-08 monitor: Efficient and quiet particle size analysis

Particle size distribution analysis is a fundamental and critical quality control test in industries such as pharmaceuticals, food, chemicals, and minerals. The EMS-08 Monitor Electromagnetic Sieve Shaker by Electrolab is an advanced instrument, designed to provide an efficient, accurate, and extremely quiet sieving process, helping laboratories achieve reliable and highly repeatable results.

Key features of the EMS-08 Monitor sieve shaker

This product is equipped with unique technologies to optimize the particle size analysis process.

Efficient 3D sieving motion

The EMS-08 Monitor produces a unique tri-dimensional movement, combining a vertical motion with a gentle rotation of the material across the sieve surface. This motion ensures that particles are spread over the entire screen, which accelerates the sieving rate and leads to higher separation efficiency.

Quiet and maintenance-free electromagnetic drive

The heart of the shaker is an electromagnetic drive that has no rotating parts. This design allows the machine to operate extremely quietly (noise level <71 dB with material), requires no routine maintenance, and has a long service life, making it ideal for a laboratory environment.

Flexible control and smart programming

Users can easily program the sieving time (1-99 minutes) and 15 different amplitude levels via the 16×2 LCD. The instrument supports two operating modes: continuous and intermittent. The intermittent mode is particularly useful for clearing blocked apertures, which increases sieving efficiency for difficult powders.

User-friendly and versatile design

The device is fitted with a special clamping device that ensures the sieves are held firmly and allows them to be quickly removed and replaced. The EMS-08 Monitor can accommodate up to 16 sieves of 100mm diameter and is suitable for both dry and wet sieving procedures (with an optional accessory).

Frequently asked questions (FAQ)

1. What is the EMS-08 Monitor sieve shaker used for?
It is used to separate the particles of a powder or granular sample into different size fractions by using a stack of sieves with progressively smaller mesh sizes. The results help determine the particle size distribution of the sample.

2. What is the advantage of the 3D motion over standard vibratory motion?
The 3D motion helps particles travel across the entire sieve surface instead of just concentrating in the middle. This prevents the mesh from “blinding” (getting clogged) and ensures all particles have a chance to pass through the screen, leading to a more accurate and faster separation.

3. What is the difference between continuous and intermittent sieving modes?
Continuous: The shaker vibrates non-stop for the entire set duration.
Intermittent: The shaker vibrates for a short period, then pauses (for 0.5 sec), and repeats. This pause helps dislodge particles that are stuck in the mesh openings, which is very effective for fine or irregularly shaped powders.

4. Is the machine noisy?
No. Thanks to the electromagnetic drive technology, the machine is very quiet. The measured noise level is less than 71 dB even at maximum amplitude with sieves and material, which is significantly quieter than mechanical sieve shakers.

5. Can I use the machine for wet sieving?
Yes, you can perform wet sieving by purchasing the optional wet sieving attachment, which is designed for 200mm diameter sieves.
