Speed-Controlled Rotary Stirrer

A speed stirrer drives the stirring paddle to rotate via a motor, ensuring uniform mixing of liquids or materials. It is used in applications such as laboratory sample preparation, paint dispersion, and chemical reactions to ensure thorough contact and reaction of materials.
Selection
When selecting, consider matching the sample viscosity with the rotational speed range, determine the size of the stirring paddle based on the container dimensions, choose a heating type if temperature control is required, pay attention to the compatibility between motor power and load, and ensure the protection rating is suitable for the operating environment.

Lab Mixer Selection - Viscosity Determines Torque
This article mainly discusses how to select a laboratory mixer based on the viscosity of the material. The higher the viscosity, the greater the torque required. Low-viscosity liquids are suitable for high speed and low torque, while high-viscosity materials require low speed and high torque.
Practical Guide to Selecting Rotors and Speeds for Rotational Viscometers
A rotational viscometer measures viscosity by detecting the resistance encountered by a rotor rotating in the sample. When selecting a rotor, it is necessary to consider the estimated viscosity range of the sample, ensuring that the torque reading falls within 10% to 90% of the instrument's measurement range, while also taking into account the sample volume and rheological properties.

If the standard disintegrator procedure for fiber dissociation is not done correctly, the first step of paper strength testing is already compromised.
Fiber disintegration is the first step in paper strength testing. If the operation is not standardized, such as inaccurate concentration, excessive time, or incorrect rotational speed, it can lead to fiber breakage or uneven dispersion, resulting in inaccurate strength data for the prepared hand sheets.
