Laboratory Roller Mixer

The laboratory blood roller mixer is a small, benchtop instrument that consists of a motor-driven roller and a platform. The platform is usually made of plastic or metal, and it has several grooves that hold tubes or bottles containing blood samples. The roller, on the other hand, is made of rubber and rotates continuously to agitate the samples.

The roller mixer was created specifically for the manufacture of homogeneous blood. Platelet, RBC, and white blood cell counts are frequently performed on a hematology analyzer. Additionally, it is employed in creating solutions containing viscous materials, mixing blood samples, and minimally aerated liquid-solid suspensions. Particularly crucial general-purpose laboratory mixing tools that support a wide range of studies are laboratory mixers and agitators.

Shakers, hotplate stirrers, rocking platforms, orbital shakers, and tube rollers are available for different mixing requirements. We'll examine all the variations and factors in this guide to assist you in choosing the mixer that will best serve your lab's needs.

Working Principle

The rotor disc revolves between 200 and 900 times per minute. The feed is loaded, and gravity pulls it downward. The feed material comes into close contact with the stationary and spinning blades due to the rotator disc's revolutions, which reduces the material's size. The same process is repeated until the desired size is achieved, with the smaller particles passing past the screen and the larger ones being caught once more by the rotating blades. The size of the rotor, the distance between the revolving and stationary blades, and the sieve opening all affect the form and size of the particles.


  • 80–100 mesh particles are the end outcome.
  • Size reduction of pharmaceuticals produced from medicinal plants and animal tissues is used for stiff and fibrous substances.
  • Additionally, it is employed in manufacturing rubber, plastics, and recycled paper.


One of the advantages of using a laboratory blood roller mixer is that it provides consistent and reproducible results. The device ensures that the samples are mixed uniformly and that any variations in the mixing process are eliminated. This consistency is crucial in laboratory applications, where the accuracy and reliability of the results are of utmost importance.

The laboratory blood roller mixer is also easy to use and maintain. The device is simple and straightforward, and it requires minimal training to operate. It is also easy to clean and maintain, and regular maintenance can extend its lifespan and ensure that it operates efficiently.

Another advantage of the laboratory blood roller mixer is that it is compact and space-saving. The device is designed to be small and lightweight, and it can be easily placed on a laboratory bench without taking up too much space. This makes it ideal for small laboratories that have limited space.


The first step in selecting a mixer is determining what performance requirements your lab needs. The factors to consider while selecting include the container capacity, speed range, viscosity range, operating temperature, introduction techniques, and temperature control. If you plan to use a mixer that has a container, there is another factor to take into account. Laboratory mixers come in various designs, each with a specific function.

The capacity to automate any procedure can free up technician and researcher time, allowing them to focus on other responsibilities since laboratories constantly expand in scope and scale. This enables them to program many contemporary magnetic and overhead stirring systems to follow predetermined stirring patterns. Modification is based on the requirements of the samples and the process.

The proper size stirrer or mixer volumes can differ from sample to sample. Ensure the rotor speed and agitator shaft sizes for overhead stirrers are sturdy enough to mix the lowest and maximum needed volumes. Making sure the plate size of magnetic stirrers or vortexes is large enough to fit the maximum volume of the sample needed will guarantee that you choose the best mixer.


Roller mixers build tube rollers for delicate mixing of collecting or conical tubes. Samples must be properly blended with the preservative added to line the tube for the best diagnostic outcomes. These rollers hold specimen tubes horizontally in place while rotating between rotors. In settings where the risk of a spilled tube is high, such as clinical laboratories, medical research, and doctor's offices, they are perfect.

There are a few things to consider when buying samples that are sensitive to temperature changes. You can buy a stirrer with a hot plate attachment to the system to manage the temperature for samples that need heat application during the mixing operation. You can purchase a stirrer with a temperature sensor to keep track of temperature changes, enabling researchers to watch the samples' temperatures in real time.
