Laboratory sieve shaker for accurate particle size analysis
In material processing industries, there’s a crucial need for precise particle size determination. Traditional methods often fall short, especially when dealing with larger sample volumes or varying material characteristics, leading to inefficiencies and inconsistent results.

Ensure reliable sieving in dry and wet conditions
The AS 450 basic by RETSCH is a laboratory sieve shaker designed to provide reliable and accurate particle size analysis for both dry and wet sieving applications. It covers a size range from 25 µm to 125 mm and handles sample loads up to 15 kg, making it suitable for processing larger quantities of material. The unit features a 3D throwing motion driven by an efficient electromagnetic drive, ensuring optimum use of the open sieve area and uniform sample distribution across the sieving surface. It also includes digital settings for time and amplitude with a memory function for storing one program. This model is specifically built for ease of use and maintenance-free operation with a robust steel housing. It’s ideal for industries such as construction materials, geology, and chemical processing.
