Laboratory rollers and mixers are instruments that are specially designed to create homogenous mixtures of two or more substances. Generally, one will find roller mixers in laboratories that conduct research on areas such as biotechnology, life sciences, and waste water treatment. However, laboratory mixers are also extensively used in other industries. They are found in labs of companies related to pharmaceuticals, food and beverage, electronics, and cosmetics. Suffice to say, laboratory roller mixers are an important product that is must have for any lab.
Basic Design and Features
Laboratory roller mixers consist of motor driven rollers that create a rocking and rolling action. They also have a paddle or a blade that supports the mixing process. This helps to create gentle movement that allows the substances in specimen bottles to amalgamate. Some of the general features that you will find in roller mixers are:
Continuous and quiet operation
Light weight and portable
Industrial grade manufacturing
Easy to clean and decontaminate
Some laboratory instrument manufacturers also design their roller mixers with features like tilting from side to side or moving up and down to ensure proper mixing.
Considerations for Purchasing Laboratory Mixers
A basic understanding of the design and features of roller mixers can be helpful in choosing one for a laboratory. However, making a decision simply based on the above information would not be wise. Like everything else related to research and development, laboratory equipment needs to be chosen by considering a few important aspects.
Choosing the Right Machine: Many a time, lab equipment sourcing personnel get confused between roller mixers and shakers. While they may seem similar, these are two different products and so are their applications.
Shakers are products that use vibrations from the platforms n which the specimen bottles are placed, thus creating the mixture. As mentioned earlier, rollers use a paddle to mix the substances together. In terms of chemical processing, these two methods will produce different results. One has to see the end result and then choose the right type of product.
Handling Liquid Viscosity: This is an important point that needs to be considered. Usually, laboratory mixers are used to mix blood samples and immiscible liquids. Every liquid will be different in terms of volume, weight, and mixing capability. The roller mixer needs to have the right settings to effectively mix two different liquids.
Roller Mixer Capacity: It is important to choose a laboratory mixer with the right number of specimen holders. This will allow you to meet your work demands in a timely fashion. Generally, one will find four to six rollers in one product. However, there are roller mixers that can mix an entire rack of bottles.
Tube Size Handling: Laboratories use different types of tubes and bottles in various sizes. Glass and plastic Bijoux and Universals tubes and bottles are generally used in the rolling mixing process. The product should have the versatility to handle all these types of bottles.
Speed and Variability: While roller mixers can be used on a continuous basis, every project has deadlines that need to be met. Once the previous points have been satisfied, the speed of the mixing process has to be taken into consideration. It should not only be able to mix the liquids at a particular speed, it should also have a feature that allows for speed variability. High speed mixing can also result in a change in temperature, so that should also be considered.
The best way to choose the right mixer product is to have a complete understanding of a laboratory’s requirements. With that information in hand, it will be extremely easy to find roller mixer that will meet all the above mentioned features.
