Rotatory mixers are laboratory instruments that mix samples by rotating them in a horizontal or vertical circular motion. They typically feature a platform or tray where containers are securely placed. As the platform rotates, the contents of the containers are evenly mixed or kept in suspension. These mixers are useful for applications such as sample preparation, reagent mixing, and maintaining consistent solutions. They often come with adjustable speed settings to accommodate different mixing needs and container sizes.

• The rotatory mixers are designed to mix samples by rotating the samples platform in 360 degree through a single axis.
• The sample fixture is simple and easy to use.
• The Rotators employ the step motors which have much accurate speed regardless the input voltages.  The minimum speedcan be set at 1 rpm.  The rotating direction can be clockwise or anticlockwise.
• The Rotators can be used in some biological samples which need gentle manner to avoid the disruption of the cells, such as blood samples etc.
• The AE-RM-30 has unique motion mode: Angular reciprocal movement. The machine can move right-to-left or left-to-right at five different angleswith variable speed (1 to 40 rpm).

🔬 How It Works?

The AE-RM-20 Series rotatory mixers operate by rotating the sample platform in a smooth 360° motion around a single axis, ensuring uniform suspension and mixing. Equipped with step motors, the mixers deliver stable and precise speeds down to 1 rpm, regardless of voltage fluctuations. The AE-RM-30 model enhances functionality with angular reciprocal movement, allowing left-to-right or right-to-left oscillations at adjustable angles, ideal for sensitive biological samples.

💡 Advantages

• High Precision Control – Step motor technology ensures speed accuracy even with varying voltages.

• Versatile Mixing Options – Choose between continuous rotation (AE-RM-20) or reciprocal angular motion (AE-RM-30).

• Gentle Handling – Perfect for biological samples like blood that require careful, non-disruptive mixing.

• Digital Timer – Set up to 9 hours 59 minutes for long or short mixing cycles.

• Compact & Lightweight – Easy to place in any laboratory setup without taking excessive bench space.

🔍 Recommended Models by Use Case

• AE-RM-20 – Best for general lab applications, routine sample preparation, reagent mixing, and solution maintenance.

• AE-RM-30 – Recommended for specialized biological research, including blood or cell suspensions, requiring angular reciprocal movement to minimize sample disruption.

🧪 Ideal For
