Mikro Air Jet Sieve

The Mikro Air Jet Sieve™ — Model MAJS-x is a highly accurate and reliable particle size analyzer designed for determining the particle size distribution of dry powder ranging from 20 μm to 4,750 μm.

Operation: The Mikro Air Jet Sieve - Model MAJS-x is easy to operate and quickly determines particle size with a short series of sieve test screens. The system utilizes the pneumatic sieving principle that enhances the accuracy and reproducibility of particle size analysis. Use of this device has become a preferred method for such tasks as quality assurance of incoming raw materials and the confirmation of final product specifications.

While negative pressure draws the particles below a defined particle size down through a sieve screen, a positive airflow is introduced upwards through a rotating wand. This airflow deagglomerates and disperses undersized particles and carries them through to the vacuum collector.

Precise particle size can be quickly determined at sizes from 20 to 4,750 μm. The unique rotating wand method also helps to reduce the need for tapping and increases reproducibility with controlled measurements of pressure drop and duration. Additionally, the operation is cleaner, quieter, and requires less space than other types of similar analytical equipment.
