Generally, lab stirrers or mixers are widely used in biology and chemistry laboratories. Although these instruments are robust, they exist in many models and devices. This is common in other types of lab equipment, such as submersible stirrers. The following are some of the factors to consider when buying lab stirrers.

Temperature Changes 

If you intend to use samples sensitive to temperature changes, it is essential to pay attention to some stirrer aspects when purchasing. For samples that need heat application during the mixing procedure, you should consider buying stirrers with a hot plate mounted to the instrument to maintain a controlled temperature. Alternatively, you can also choose to immerse the vessel inside a water bath for samples mixed using an overhead stirrer. Many brands now produce stirrers with a mounted temperature sensor to keep track of temperature changes, allowing users to monitor the temperature.

The Volume of the Sample

Since volumes of samples differ, it is essential to pay attention to the volume of the stirrer or mixer when purchasing it. Moreover, it is crucial to ensure the rotor speed and sizes of the available agitator are sufficiently robust to mix the sample’s highest and lowest volumes when it comes to purchasing overhead stirrers. If you intend to buy a magnetic stirrer, you should ensure the plate is adequately large to accommodate the maximum volume of sample needed.

Sensitivity of the Samples on Time or Agitation

Since labs are always developing in terms of size and scope, the capacity to automate a process can save time for the stirrer user to finish other activities. Due to this reason, most overhead and magnetic stirring systems can be programmed to undertake particular stirring patterns based on the requirements of the process and samples.

Purchasing the right stirrer for your activity enhances the effectiveness of the process. If you intend to buy lab stirrers, the above tips can be useful.
